Mounting Steps
The thermostat adopt pre-guide and limited snap-fit design. It is easy to mount.
- Release front cover by inserting a head screw-driver into bottom crack.
- Insert the wires and then fix these wires with screws. Suggested wire-stripping length is 7-9mm.
- Mount backing plate into wall-cassette, put screws and then fix thermostat. Make sure that the thermostat is fixed without deformation. Suggested torque is 0.2~0.4N.m (2.0~4. 1kgf.cm).
- Re-mount the front cover via snap-fit connection.
Sensor failure
Please select work mode of sensors correctly. When it shows EO/E1 error, thermostat will stay power-off till the error is eliminated. EO: built-in sensor is short-circuited or disconnected.
E1: floor sensor is short-circuited or disconnected.
Connecting Diagram
The thermostat operates in full capacity in areas with the altitude of less than 2500 above sea level. Power rating of external load should be less than or equal to 80% rated power of the thermostat in areas with altitude of 2500m to 4200m.
