Standard Motor Kit

The Standard Motor Kit is intended to motorize casement and awning windows with crank-operated window hardware. If you are motorizing a skylight you must use a Skylight Motor Kit.

Wintrol has been motorizing casement and awning windows for more than 20 years. It's been our experience that one of the most difficult things a person faces when motorizing their casement or awning window, is correctly identifying which installation kit he or she will need to connect the motor to the window's operator hardware. There are literally 100's of different hardwares used in the United States alone. To make matters even more interesting, there have been several window manufacturers who have "evolved" their hardware, making subtle changes that rendered some installation kits "non-fitable" from one year to the next.

In an effort to assist in the process of identifying your window's operating hardware, we have supplied a number of pictures below. While you may not find an exact representation of your window’s hardware, you should find something similar. If you read the notes next to each picture you will find tips and clues you can follow to correctly determine if an installation kit is available to meet your needs.

Standard Motor Kit

This kit contains:
A 24 VDC drive motor.
An installation kit containing all mounting hardware. The kit is specific to the hardware that actuates the window or skylight being motorized.
A Wintrol Motor Cover or Truth Motor Cover in one of three colors (bronze, off-white, or champagne).

Note: The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Note: A Control Switch is not included in this kit. If you don't already have a Control Switch it must be purchased as a separate item (LC-I Control Switch or LC-II Control Switch) or as a kit (LC-I Control Switch Kit or LC-II Control Switch Kit).

A Control Switch is required to operate a Standard Motor Kit. However, since a Control Switch can control up to three motors, one Control Switch can operate up to three matching windows or one window with up to two Motorized Locks. If the windows are used as a group, each window will move, in sequence, to the same position during an open or close operation. Independent control of a single window in a group is not possible.

To see how the Standard Motor Kit integrates with all of our other components to form a complete system for motorizing your casement, awning, and skylight windows, take a look our wiring diagram. It should give you a basic guideline for planning and creating your own motorized window system. You can also see the Standard Motor Kit Installation Instructions below to give you an overview of the steps needed to install your Standard Motor Kit.

If you have reviewed the information below and you are still not sure what operator hardware your casement or awning window uses or if it can be motorized, open your window far enough to see the hardware, take a close-up digital picture, and send it to us at for assistance. After 20 years in the business we pretty much know all the casement and awning hardware being used. If you have a digital picture of any "oddball" operator hardware, we would very much like to see it so we can continue to add to our list of identified mechanisms.

Below are some casement and awning window operator mechanisms that can be motorized with our Standard Motor Kit.

Truth Side-Drive Operators

You can click on the picture to the left for larger view of this operator.

This is a casement window operator by Truth Hardware. A single arm swings through a track while pushing the window open or pulling the window closed. If you look closely at the arm that is visible when the window is open, you will find "Truth" stamped into it. Some of the hardware of this style has a plastic cover over shaped steel parts instead of a cast body as you see here. You can be certain if you count 12 ridges around the spindle when the crank handle is removed.

When motorizing windows with an side-drive (offset) design, the Wintrol Motor Cover will provide more complete coverage of the motor. You can look at all of the Truth side-drive operators to help you fully identify your casement or awning window hardware.

Please be sure Wintrol supports motorizing your casement or awning window operator hardware before you order the Standard Motor Kit.

Truth Center-Drive Operators

You can click on the picture to the left for larger view of this operator.

This is a common operator for awning windows by Truth Hardware. A pair of arms spread across a track or operate an elbow mechanism to provide the push and pull for opening and closing these windows. If you look closely at the arm that is visible when the window is open, you will find "Truth" stamped into it. Some of the hardware of this style has a plastic cover over shaped steel parts instead of the cast body as you see here. You can be certain if you count 12 ridges around the spindle when the crank handle is removed.

When motorizing windows with a center-drive (centered) design, the Truth Motor Cover will provide more complete coverage of the hardware. You can look at all of the Truth center-drive operators to help you fully identify your casement or awning window hardware.

Please be sure Wintrol supports motorizing your casement or awning window operator hardware before you order the Standard Motor Kit.

Pella Operator

You can click on the picture to the left for larger view of this operator.

If you look closely, you will find Pella has their name molded into the operator mechanism somewhere on or near the hand crank. Pella operators also have 11 ridges around the spindle that you can count when the handle is removed. Wintrol motorizes Pella windows on a regular basis. The Standard Motor Kit for these windows includes a Wintrol Motor Cover and a mounting bracket which is designed to fit the shape of the sill molding.

There are two types of Pella operating hardware for casement and awning windows. The first type, shown in the picture, has a fold-down handle. The second type has a fixed handle. Pella's Large Commercial Awning Window may be equipped with a Truth Center-Drive Operator. Be sure that you order the correct Standard Motor Kit from the options below.

Andersen Operator

You can click on the picture to the left for larger view of this operator.

This is a current Andersen operator used on casement windows. Installation kits for Anderson windows are special order only. Andersen has 12 ridges around the spindle that you can count when the handle is removed. Unfortunately, Andersen has incrementally increased the diameter of their spindle several times over the last decade. It can be difficult to determine which spindle you must fit. Note: The Truth Adapter will not fit. If you must motorize the Andersen window, please contact Wintrol for advice and costs.

Below are some casement and awning window operator mechanisms that cannot be motorized with a Standard Motor Kit at this time.

Oblique Operator #1

You can click on the picture to the left for larger view of this operator.

This is a casement window operator most commonly found on aluminum or vinyl windows. Please note the angle of the drive spindle exiting this hardware. Wintrol does not support motorizing this hardware. The oblique angle of the spindle does not allow the motor to properly align with the window to enable a bracket and cover to function as intended. Furthermore, should the thought cross your mind that some form of universal joint might allow you to install a motordrive - it's been tried and the results were unacceptable.

Oblique Operator #2

You can click on the picture to the left for larger view of this operator.

Standard Motor Kit Installation Instructions

You can download the Motor System Installation Instructions (1.26MB) to familiarize yourself with the Standard Motor Kit installation. The installation instructions are in Adobe PDF format and require Adobe's free Acrobat Reader. If you don't have Acrobat Reader you can download it from Adobe's website.

Step 1 - Gather Your Tools

#2 Philips head screwdriver
1/8" (3.0 mm) bladed screwdriver
1/10" (2.5 mm) bladed screwdriver
Electric drill motor
Drill bits (1/4" and 1/16")
An awl for marking mounting holes
Class II, low voltage wire for the motors, switches, and transformers
An assortment of wire nuts

Step 2 - Run Electrical Wires

Use Class II stranded wire for all connections.
Use the table below to select the wire size for transformer and motor connections. Stranded wire is recommended for all transformer and motor connections.
Run the wires to the motors, switches, and transformers. Low voltage wires should be at least 12" away from high voltage (120 VAC or higher) wires to avoid any electrical interference.

Class II Wire Size	Total Distance Transformer To Farthest Window
18 AWG stranded	50 ft (15 m) maximum
14 AWG stranded	100 ft. (30 m) maximum
12 AWG stranded	150 ft. (45 m) maximum

Step 3 - Prepare the Window

The window must operate smoothly. Lubrication or cleaning of the hardware may be required.
If it is convenient, install the motor while the window is open one or two turns. This will make verifying the correct automatic startup closure easier to determine.

Step 4 - Install Spline Adapter

Install spline adapter 1. Make sure the window is open one or two turns.

2. Remove the handcrank from the window hardware.

3. Install the spline adapter (B) on the operator shaft. The Allen wrench is included in the installation kit.

Step 5 - Install Motor On Window

Install window motor 1. Install the motor by slipping it over the spline adapter as shown. The motor can be installed "flat side down" or "flat side up". Select the orientation that best fits your window. Note: When mounting the motor "flat side down" cover the screwhole with tape to prevent grease leakage.

2. For casement and awning window installations, position the bracket for the best motor alignment.

3. Using the motor as a template, establish the location for the mounting bracket (C).

4. Drill 1/16" pilot holes for the mounting screws to avoid splitting the sill before installing the screws. Due to the high torque of the motor, two screws must be used when mounting the bracket to wood or plastic. Do not fully tighten the screws yet.

5. If the motor wires are going to be hidden by the window frame, drill a 1/4" hole in the sill to run the motor wires through.

6. Secure the motor with the bracket. Be sure to use both the rubber isolation grommet (D) and the push-on fastener (E).

Step 6 - Align Motor

Align motor 1. Align the motor to the window. In some applications shimming may be required for proper alignment.

2. Tighten the screws in the bracket.

3. Tighten the setscrew in the black plastic alignment collar (F). Caution: Do not over-tighten the setscrew.

Step 7 - Install Screen Interlock

Install screen interlock 1. Install the screen interlock (G) as shown using the #6 x 3/8 PH screw (H) supplied.

WARNING: The screen interlock must be correctly installed. It is intended to prevent personal injury and/or window damage during operation. The correct installation of the screen interlock is the responsibility of the installer.

Step 8 - Connect Motor Wires

Connect motor wires 1. Connect the motor wires per the wiring diagram.

2. Secure the wires to the motor with tape.

Step 9 - Install Motor Cover

Install motor cover 1. Some applications will include a Truth Motor Cover that attaches with a screw, as seen in the diagram to the top left.

2. Install the Truth Motor Cover using a #6 x 3/8 PH screw (I) found under the cover button (J). WARNING: Use of a longer screw will damage the motor.

3. Some applications can use Wintrol's Motor Cover, as seen in the diagram to the bottom left.

4. Install the Wintrol Motor Cover using the Velcro strips included with the Wintrol Motor Cover. Refer to the diagrams just below.

Install Wintrol motor cover 5. As seen in the diagrams to the left, in some applications you can mount the motor closer to the sill and enable Wintrol's Motor Cover to dress completely down to the woodwork. Note: When mounting the motor "flat side down" cover the screwhole with tape to prevent grease leakage.

6. The Wintrol Motor Cover has two thin alignment posts. These posts level the cover when mounting the motor "flat side down" (top diagram). If the motor is to be mounted "flat side up" (bottom diagram) the alignment posts should be removed.

7. The use of Velcro to retain the cover permits the installer to easily adjust the Wintrol Motor Cover's fit and maximize coverage of the motor.

8. To install, pull the fuzzy-side of the Velcro away from the prickly-side (attached to cover), remove the backing tape, and place of each side of the motor as indicated in the diagrams.

Step 10 - Install Rain Sensor

Note: The Rain Sensor is available only on the LC-II Control Switch.

Do Not use the Rain Sensor if the window is being used as a smoke vent or if "Open & Hold" is required. Refer to Open & Hold Switch Installation.
Install the Rain Sensor with the "grid" exposed. To avoid water pooling, do not mount flat.
The Rain Sensor can be mounted outside (maximum sensitivity) or inside the vent edge (minimum maintenance).
A Rain Sensor can be connected to every LC-II Control Switch, RS Module, and IR Receiver in your system. However, when RS Modules or IR Receivers are used the Rain Sensor could be connected to one of them and not to the LC-II Control Switch.
Use 22 AWG, 2-conductor, shielded, twisted-pair wire, 50 ft. (15 m) maximum. Run low voltage wires at least 12" away from high voltage wires to avoid any electrical interference. Connect the shield to GROUND (G). Refer to the wiring diagram for more information.

Step 11 - Install LC-I Control Switch and LC-II Control Switch Jumper Setting

The LC-II Control Switch is pictured. The LC-I Control Switch does not have the option connector. The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Install jumper setting
Jumper Block

1. Verify the jumper setting on the Control Switch is correct for your application.
A - For windows with Motorized Locks.
B - For skylights.
C - For windows without Motorized Locks (no jumper installed).

Step 12 - Connect LC-I Control Switch and LC-II Control Switch

The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Connect LC Control Switch 1. The Control Switch can control up to three matching windows, OR three matching skylights, OR one window with up to two Motorized Locks.

2. Connect the Control Switch per the wiring diagram and the connectors table below. There must be one transformer for each Control Switch.

3. Mount the Control Switch in a single gang electrical box.

LC-I Connectors

Symbol	Connection	Description
P	Power	Input from 24 VAC transformer. There must be one (1) transformer for each LC-I Control Switch.
MC	Motor Common	The common (ground) connection to all motors.
M1	Motor #1	The "hot" output connection to motor #1.
M2	Motor #2	The "hot" output connection to motor #2.
M3	Motor #3	The "hot" output connection to motor #3.

LC-II Connectors

Symbol	Connection	Description
P	Power	Input from 24 VAC transformer. There must be one (1) transformer for each LC-II Control Switch.
O	Open	The unit(s) will open when this input is connected to ground (G). If this contact is continuous the unit(s) will be held open (Open & Hold) with all other inputs ignored, except the Rain Sensor (R). If this contact is momentary (one second minimum) the unit(s) will open and wait for a close command. Any additional open commands will be ignored. If the unit(s) is opened by a momentary open signal and closed by the Rain Sensor, the unit(s) will not reopen when the Rain Sensor dries off. If the unit(s) is opened by a continuous open signal and closed by the Rain Sensor, the unit(s) will reopen when the Rain Sensor dries off.
C	Close	The unit(s) will close when this input is connected to ground (G). If this contact is continuous the unit(s) will be held closed (Close & Hold) with all other inputs ignored, except Open & Hold which has the highest priority. This is an important mode of operation! For example, you may want to use this as a "vacation" mode for home automation systems where all unit(s) should close, and remain closed, while you are on vacation. If this contact is momentary (one second minimum) the unit(s) will close and wait for an open command. Any additional close commands will be ignored.
G	Ground	Signal ground.
F	Feedback	This connection is not an input. When the LC-II Control Switch determines that the unit(s) are closed this output signal will be driven to approximately 24 VDC with respect to ground (G). Conversely when this output is at 0 VDC, the unit(s) is open. It must be stressed that this output must not be used as the sole means of determining window position for security purposes.
R	Rain Sensor	Rain Sensor inputs (2). Moisture on the Rain Sensor will cause the unit(s) to close.
MC	Motor Common	The common (ground) connection to all motors.
M1	Motor #1	The "hot" output connection to motor #1.
M2	Motor #2	The "hot" output connection to motor #2.
M3	Motor #3	The "hot" output connection to motor #3.

Step 13 - Connect Transformer

The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Connect transformer 1. Install a Free-Air Transformer (pictured to the left) on a 4" x 4" junction box in a cool, dry location. The surrounding air temperature must not exceed 150° F (65° C). A Plug-In Wall Transformer can be plugged into any convenient wall socket.

1. Connect the transformer per the wiring diagram. There must be one transformer for each Control Switch.

Note: Installation must meet local and National Electrical Codes (N.E.C).

Note: Connecting the transformer directly to the motor can cause damage.

Step 14 - Powering Up the System and Testing

Note: Before powering up the system all motors must be installed and correctly wired per Steps 1 through 13.

The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Because some windows open clockwise when the handcrank is turned and some open counter-clockwise it is important to determine which direction the window travels when power is applied.

Upon connecting power to the transformer wait 15 seconds without pushing any buttons. The system should automatically close all windows. Windows already closed should remain closed.
- If any of the units open, power should be disconnected and the motor wires to those units must be reversed either at the motor or at the switch.
- If any of the units fail to open or close, see the Troubleshooting Guide below.
If all windows closed correctly, press the "Reset" button on the front of the Control Switch. After a few seconds the Control Switch will automatically open each window to its full range of available travel. The Control Switch will then close each window. This procedure may take several minutes. Once the windows have closed again, the system is ready for normal operation.
After the system has been "Reset", momentarily pressing "Open" will open all units, one at a time, to the automatic vent position (approximately 80% of available travel). The units may be opened further for cleaning or servicing by holding the "Open" button after the vent position is reached. "Close" will completely close all units from any position. Note: Special open positions can be attained by pressing the button for the opposite direction of travel while the motor is running. This will halt the moving unit and move all other units to the same approximate position.
Each screen interlock must be checked when the unit is running. The motor should stop when the screen interlock is disconnected. Correct installation is the responsibility of the installer. Note: The system must be reset after each test.

Troubleshooting Guide

The term "Control Switch" refers to either the LC-I Control Switch or the LC-II Control Switch.

Symptom	Possible Solution
Unit does not operate, no sound from the motor.	1. Press the "Reset" button on the Control Switch to reinitialize the system. 2. Refer to the wiring diagram and check the connections. 3. Check for power at the transformer for 110-125 VAC input and 24 VAC output. 4. Check the screen interlock connection.
Unit makes a noise, but the window will not move or operates erratically.	1. Press the "Reset" button on the Control Switch to reinitialize the system. 2. Be sure the window is unlocked. 3. Be sure the window will operate freely without the motor attached. 4. Remove the motor cover and test. Be sure the cover screw length is #6 x 3/8 PH. 5. Control Switch may be incorrectly wired to the motor. Refer to the wiring diagram.
Unit runs slowly.	1. Due to gear reduction in different operators, the speed will vary.
Unit makes excessive noise during operation.	1. Check that the rubber isolation grommet was installed. Refer to Step 5, Install Motor On Window. 2. Be sure the motor cover is tight. 3. The unit will be louder on a metal window frame.
Unit does not close completely.	1. Press the "Reset" button on the Control Switch to reinitialize the system. 2. Be sure the window will operate freely without the motor attached. 3. Disconnect the power and refer to Step 14, Powering Up the System and Testing. 4. Check the jumper setting for the application. Refer to Step 11, Install Control Switch Jumper Setting.
Unit runs continuously in one direction when bench testing.	1. The motor must be connected to a window for correct operation. Note: Connecting the transformer directly to the motor can cause damage.
Unit closes when the "Open" button is pressed.	1. Motor leads are reversed. See Step 14, Power Up the System and Testing.

Optional Control Input Instructions

Only the LC-II Control Switch has the Optional Control Inputs available. The LC-I Control Switch does not have the Option Connector.

Control Input Priority

Momentary contact closure will cause the system to respond to the last command given.
Continuous contact closure will override any momentary contact closure.
A continuous contact closure to open has a higher priority than any contact closure to close.
The Rain Sensor, since it is not a contact closure, will close the unit(s) even if the unit(s) are held open by a continuous contact open command. When the Rain Sensor dries off the unit(s) will again open.

Open & Hold Switch Installation

This feature is designed for use with thermostat and smoke vent systems. Note: DO NOT use Open & Hold Switches with a Rain Sensor because the Rain Sensor will override the Open & Hold Switch.
Use a SPST (Single-Pole, Single-Throw) continuous contact relay or switch for this low voltage control application.
Connect the controlling contact between the OPEN (O) and GROUND (G) connectors on the LC-II Control Switch.
When this contact is held closed the unit(s) will open, and remain open, regardless of the state of any other inputs, except for the Rain Sensor.

Close & Hold Switch Installation

This feature can be used when leaving a building to close the unit(s) and prevent any unattended device (such as a thermostat) from opening the unit(s). It can also be used for a security system interface. This feature should not be relied upon for security system purposes.
Use a SPST (Single-Pole, Single-Throw) continuous contact relay or switch for this low voltage control application.
When an IR Receiver is NOT used, connect the controlling contact between the CLOSE (C) and GROUND (G) connectors on the LC-II Control Switch and/or the RS Module. When using an IR Receiver the contacts should be between the CLOSE & HOLD (F) and GROUND (G) connectors on the IR Receiver.
The "Close & Hold" feature overrides all inputs except "Open & Hold".
