Installation & Wiring
Location:
Thermostat is suggested to be installed indoor, a place with around 1.5m height above the floor
where represents the average room temperature. It should be away from direct sunlight, any cover, or
any heat source, to avoid false signal for temperature control.
CAUTION: Cut off power supply at circuit breaker or fuse before installation to avoid fire, shock
or death!
Step 1: Remove the steel frame from the device, and secure it onto the junction box with two screws.
Step 2: Insert all wires into the right terminals and tighten screws. The wiring diagram is shown below.
Step 3: Attach the wired device on “A” points of the steel frame as shown first, and then push the
whole device into junction box.
Step 4: Confirm the device is well mounted, power on and it is ready to operate.

and then press or to set the parameters of flashing item. Press “M” ,or wait for 15s to save the
value and return to display.
Working Mode Setting
Touch “M” to enter working mode setting, the current mode flashing. Press or to switch
among Cooling , Heating & Ventilation mode, then press “M”, or wait for 15s to
confirm the choice.
Temperature setting
Touch or to set local temperature value. Hold the buttons can set continuously. Press
“M” , or wait for 15s to save and return to room temperature display.
Fan Speed setting
In normal display, press to switch among the fan speed :“ Low, Medium, High, Auto” ; Then
press “M”, or wait for 15s to confirm the choice.
Note: In Ventilation mode, no Auto speed choice.
Fan Manually control
If fan speed is manually set , the device still auto control the fan in such situation:
Cooling Mode：
Room temperature ≤ setting temperature, valve closes and fan stops;
Room temperature ≥ setting temperature +1 ℃, valve and fan opens.
Heating Mode：
Room temperature ≥ setting temperature, valve closes and fan stops;
Room temperature ≤ setting temperature -1 ℃, valve and fan opens.

Parameter Setting
Power Failure Memory
Under the shutdown state, press & hold will enter interface for power failure memory
selection，“PAGE”displays. Press or to change setting value, then press “M” to confirm and
return.
After power failure:
000 (default) indicates device will be in shutdown state (“OFF”) when power on again;
001 indicates device will be in working interface when power on again;
002 indicates device will stay the status before power failure when power on again.
Temp. Calibration/ Temp. Setting Range
Under the shutdown state, press & hold will enter interface for temperature calibration,
“-ERR”displays. The calibration range is among -5.0 ~ +5.0 ℃.
Press or to change setting value, then press “M” save and enter interface for temp.
