1. Remove the packing material from the thermostat. Gently pull the control panel straight off
the base. Forcing or prying on the thermostat will cause damage to the unit.
2. Connect wires beneath terminal screws on power supply module using appropriate wiring
schematic. See figure 4
3. Push power base into 86mmX86mm conduit box.
4. Using two mounting screws mount the power base to the wall. Place a level against bottom
of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will
not affect thermostat operation.)
5. Replace control panel on the power base by snapping it in place

WARNING: ELECTRICALSHOCK HAZARD

Turn off power at the main service panel by removing the fuse or switching the appropriate
circuit breaker to the OFF position before removing the existing thermostat.
IMPORTANT:
Thermostat installation must conform to local and national building electrical codes and
ordinances.

CHECK THERMOSTAT OPERATION
Switch on the thermostat
Fan operation
1. Push fan button, display will show and Auto, separately means fan rotate in HIGH,
MED, LOW, or AUTO speed.
2. If you select AUTO speed, fan operation will change speed according to the difference
between the room temperature and setting temperature. If room temperature is 3℃higher
than setting temperature in cooling or3℃lower than setting temperature in Heating. Fan
will run in High speed. If room temperature is 2℃- 3℃higher than setting temperature in
cooling or 2℃-3℃lower than setting temperature in Heating. Fan will run in Medium speed.
If room temperature is 0℃-2℃higher than setting temperature in cooling or 0℃-2℃lower
than setting temperature in Heating. Fan will run in Low speed.
Heat system operation
1. Press system switch to into Heat mode ( )
2. Press “ ” to adjust the thermostat setting above the room temperature. The heating
system should start to operate.
3. Press “ “ to adjust the thermostat setting below the room temperature. The heating
system should stop operating.
Cooling system operation
1. Press system switch to into Cool mode ( )
2. Press “ “ to adjust thermostat setting below the room temperature. The cooling system
should start to operate.
3. Press “ ” to adjust temperature setting above the room temperature. The cooling system
should stop operating
Internal sensor & external sensor control mode
Internal sensor is room’s temperature sensor; external sensor is fan coil unit’s temperature
sensor.
Terminals 8 & 9 connected with external sensor for measuring room temperature. Internal
sensor & external sensor can automatic exchange. When you connected with external sensor, the
internal sensor will lose function, the measuring room temperature is external sensor’s surface
temperature. When you didn’t connect with external sensor, the measuring room temperature is
internal sensor’s surface temperature. It means you can only select one sensor for measuring
room temperature.
CONFIGURATION
The configuration menu allows you to set certain thermostat’s operating characteristics to
your system or personal requirements.
Switch off the thermostat and hold the sleep operation Button ③for over 4 seconds till power
on again means you have entered the first configuration menu item. There are 8 menu items. press
button ③to change to the next item. To exit the menu and return to the normal operation, switch

off the thermostat and switch it on again. If no keys are pressed within 20 seconds the thermostat
will be switched off. To revert to factory default setting, press button ③for over 3 seconds in
configuration menu item, all the configuration setting has reverted to factory default setting.
