Installation & Wiring g
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.

 Valve Output Voltage Display
In the state of power on/off，long press to enter into valve output voltage interface, the valve output voltage
value will be displayed in the area of temperature. Output range:0~10V.
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.
