Thank you very much for selecting our thermostat control and air conditioning (AC) of 12 volt window motors, including single hung window motors, louvres, and awning window openers with stainless steel chain. Note that you can also use these in RV applications.

Please read this manual prior to installation and before use for correct application and maintenance.

Please Note: The temperature sensor probe MUST BE CONNECTED to terminal 3 and 4, otherwise you will get an "Error" (Er) message on the display.

We have separated the instructions to provide for a A. Quick Start Guide - please see B. Detailed Notes at the end of this page.

A. Quick Start Guide for Powered Motors:

Main Features:

Fahrenheit or Celsius can be displayed.
Automatic switching between heating and cooling modes.
Control the temperature by setting the upper limit and difference.
Using an accurate thermometer, the thermostat can be calibrated.
Compressor output delay protection for refrigeration.
Alarm sounds when temperature exceeds the limit or temperature sensor fails.

Operation:

If the measured temperature is greater than the temperature set value, the thermostat commences COOLING - the COOL LED is turned on, and the relay is activated.
If the measured temperature is less than the temperature set value, the COOL LED is turned off, and the relay turns off.

If the measured temperature is less than the temperature set value - DIFFERENCE set value, the thermostat commences HEATING - the HEAT LED is turned on, and the relay turns on.
If the measured temperature is greater than the temperature set value - DIFFERENCE set value, the HEAT LED is turned off, and the relay turns off.

Please Note: After SAVE (Power button), the controller will display "Er" for 3 seconds (if there is an error), and the alarm will sound. Press any button to disable alarm.

To Set Compressor Delay (Pt-compressor 0 to 10 minutes delay):

For window motors, this is disabled (0 minutes), but can be set to a maximum of 10 minutes. Please see instructions above if you need to change this, but the display will change to "Pt".

To Set Calibration of Measured Temperature:

This is normally done with an accurate thermometer. If you take a reading from the thermometer, you can set the thermostat to the same setting. Here are the steps:

Hold down the S button for a minimum of 3 seconds
You should see a tS displayed (SET LED is lit)
Press and release the UP button until you see CA displayed
Press and release the S button
Adjust the UP or DOWN keys until the desired temperature is displayed
Press and release the POWER button to SAVE the setting (measured temperature will be set)
The system will change to the measured temperature

Please Note: After SAVE (Power button), the controller will display "Er" for 3 seconds (if there is an error), and the alarm will sound. Press any button to disable alarm.

To Set Fahrenheit or Celsius:

We have not included this in the Quick Start guide because we normally pre-program this setting. Please see the "B. Detailed Instructions" below, if you need to change this.

B. Detailed Instructions for Automating Thermostats:

Error Messages on LED Display:

Please Note: The temperature sensor probe MUST BE CONNECTED to terminal 3 and 4, otherwise you will get an "Error" (Er) message on the display.

If the temperature sensor is disconnected, or short circuit, or open circuit (temperature sensor probe is possibly defective), the thermostat controller starts sensor error mode and disables the system. The buzzer alarm sounds and the screen displays Er - you can press any key to silence the alarm.

The system will return to normal working status and the measured temperature will be displayed.

Over-Temperature Alarm:

When the measured temperature exceeds the measured temperature range, the system starts the over-temperature error alarm mode and disables the thermostat controller. The buzzer alarm sounds and the screen displays HR - you can press any key to silence the alarm.

The system will return to normal working status when normal temperature range is detected (the measured temperature will be displayed).

Safety Precautions:

The thermostat and motors are powered by 12 volts DC, so there is no shock hazard.

Ensure that the product is used within specifications, especially especially the relays. Our single/double hung motors and awning window motors use a maximum of 2 amps, and our heavy duty actuators use a maximum of 4 amps. The relays are rated at a maximum of 10 amps of current.

Do not allow metal fragments, wire clippings, fine metal shavings or file residues to enter the thermostat during installation - otherwise it could fail.

Do not allow the thermostat to be used in the presence of flammable and explosive gases.

If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur. Always consider the application conditions and use the output relays within their rated load and electrical life expectancy.

To Restore Default Settings:

If the thermostat controller is changed from Celsius to Fahrenheit (or system is changed from Fahrenheit to Celsius), all the settings are changed to the default values:

When the set temperature is degrees Fahrenheit:

tS - temperature set value: 50.00 °F
dS - difference value: 3.00 °F
Pt - compressor delay: 3 minutes
CA - calibration: 0 degrees

When the set temperature is degrees Celsius:

tS - temperature set value: 10.00 °C
dS - difference value: 1.00 °C
Pt - compressor delay: 3 minutes
CA - calibration: 0 degrees
