2Insert the wires and then fix these wires with screws. Suggested wire- stripping length is 7-9mm.
3Mount 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).

4Re-mount the front cover via snap-fit connection.

Installation instructions

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.
