Diagram and Description

Wall locations

The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.

Do not install thermostats at the following places:

• Close to hot or cold air ducts
• With direct sunlight
• With an outside wall behind the thermostat
• The areas that do not require conditioning
• Where there are dead spots or drafts (in corners or behind doors)
• Where there might be concealed chimneys or pipes

Installation Tip
Pick an installation location that is easy for the user to access. The temperature of the location should be representative of the building.

SUBBASE INSTALLATION

Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

Caution: Equipment damage hazard
Do not operate the cooling system if the outdoor temperature is below 50° F (10° C) to prevent possible compressor damage.

• Insert the awl into the slot and pry up the front part of the panel to open it.
• For horizontal mount put one screw left and one screw right.

WIRING

Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can cause electrical shock or equipment damage.

Wiring

1. If you are replacing a thermostat. Take notice of the terminal connections on the cases, the wiring connections may not be colour-coded. For example, the green wire may not be connected to the G terminal.
2. Loosen the terminal block screws. Insert wires then retighten terminal block screws.
3. Place non-flammable insulation into the wall opening to prevent drafts.

Warning:
All components of the control system and the thermostat installation must conform to Class II circuits per the NEC Code.

Caution:
Do not over-tighten terminal block screws, as this can damage the terminal block, and keep the thermostat fitting on the sub-base correctly or it will cause system operation issues.

• Max Torque = 6in-lbs

Terminal Designation

• C Common wire from the secondary side of the cooling system transformer
• O Heat pump changeover valve energizes in cooling
• B Heat pump changeover valve energizes in heating
• W Heat relay
• RH Transformer power for heating
• RC Transformer power for cooling

Operation

1. COOL/HEAT/OFF: press the” COOL/HEAT/OFF ” key once to turn on the system. The mode is cool and” ” is displayed. Meanwhile, the room temperature, setting temperature, and the clock will be also displayed. Change to the heat mode by the second pressing and” ” is displayed. Press again to turn off the system and “off” is displayed.
2. Setting temperature: when power is on, press” “or” “to set the temperature. Press “ “to lower the setting temperature, and press” “to raise the setting temperature.
3. Fan mode: When powered on, press it to choose the fan on and press it again to change the fan to auto mode.
4. Run key: When power is on, press the key to run the program that has been set. Meanwhile “Run On” is displayed. In the programming mode or changing the system parameter, press “RUN” to exit and save the changed parameter.
5. Hold key: When powered on, press the “Hold” key to keep the setting temperature. It won’t run the program and display “Hold”. For example: now the setting temperature is 60°F, after pressing the “HOLD” the system will lock the setting temperature to be 60°F.

Programming setting
When powered on(in cool /heat mode), hold “SET” for 3 seconds to enter the programming mode:

1. The first is to set the system clock. When the clock area is flashing, press” ” or” Q” to change the clock. And if you hold “ ” or “ “, the adjustment will be faster.
2. Press” SET” again to set the week. When the week flashes, press” ” or” ” to change the week.
3. Press” SET” again to set the Wake time for Monday. When the clock area is flashing, press” ” or” ” to adjust the time.
4. Press” SET” again to set the Wake temperature for Monday. When the clock area is flashing, press “ ” or” ” to adjust the temperature.
5. Repeat pressing the” SET”, then you can set the time and temperature of Leave, Return, and Sleep, from Monday to Sunday by turn.
6. After finishing the setting, press the” RUN “to cancel the setting interface and save the parameter. (if there’s no operation within 30 seconds when setting, the system will exit the setting interface and abandon the changed parameter.)

EXAMPLE:
Heating/Cooling Schedule Plan(Factory default program setting)

System parameter setting
When power is off, hold the ” SET ” key for 5 seconds to enter the parameter- changing interface. The room temperature area displays each symbol of the parameter, and the system clock area displays each parameter of the parameter values. Repeat to press the ” SET ” key to cycle display each parameter. Press “ ” or” ” to adjust each parameter. After finishing changing, press the ” RUN “key to exit the setting interface and save the set parameter. (if there’s no operation within 30 seconds when setting, the system will exit the setting interface and abandon the changed parameter.)

1. Select the cooling cycle rate
   The FA setting is used to produce shorter cooling cycles. The SL setting produces a longer cooling cycle. Both settings produce very accurate temperature control and can be set to your personal preference.

2. Select the heating cycle rate
   The FA setting is used to produce shorter heating cycles. The SL setting produces a longer heating cycle. Both settings produce very accurate temperature control and can be to your personal preference.

3. Select °F or °C readout
   Changes the display readout to Centigrade or Fahrenheit as required. The default setting is “°F”.

4. Select compressor lockout delay
   To protect the compressor from short cycling, you can select a compressor off- time cycle between O and 5 minutes. When the thermostat compressor time delay occurs, the Cool On or Heat On display will flash during the compressor lockout. The default setting is “5”.

5. Select temperature recalibration
   This feature allows you to adjust the displayed room temperature up to 5° higher or lower. Your thermostat can be accurately calibrated to match your previous thermostat. The current or adjusted room temperature will be displayed on the display. The default setting is “0”.

6. Choose traditional mode or heat pump mode
   Users can choose traditional mode or heat pump mode according to their condition. When the heat pump mode is set, the compressor will have a force- minute delay to restart.

7. Choose the reversing valve of the heat pump
   Users can choose the reversing valve working on the heat mode or the cool mode. In heat pump mode, please check the reversing valve to see whether it is in the O or B position, and enter the system to set the reversing valve to the position you need.

8. Intelligent Recovery Option
   The thermostat has an intelligent recovery function that brings your room temperature to exactly the pre-set time by turning on the Heating earlier. Select 1 to activate the intelligent recovery function, and Select to deactivate the intelligent recovery function. The default setting is “O”.

9. Heat fan control
   This function is the control and choice for the heat fan. If the user uses the Gas or Oil heating system, please choose “Gas”(system controls fan operation) If the user uses the Electric heating system, please choose “Electric”(thermostat controls fan operation).
