Before installation

1. Make sure that all the parts and tools needed for the installation are available.
2. Make sure that heating load is equivalent to the thermostat power endurance.
3. Measure the insulation resistance and circuit resistance of the heating load controlled by the thermostat.

Installation, figures 1, 2 and 4

1. Mount the thermostat as the cover of a 1-component mounting box or as a part of a multiple component instrument panel.

2. Place the sensor cable in a dry protective tube between heating cables.
   NOTE! Make sure that there is not water in the protective tube.

3. Connect the earthing wires (PE) to the separate connector.

4. Connect the thermostat to the mains and load according to figures 1 and 2.
   • Connect the supply conductors. The stripping length is 9 mm.
   • Connect the sensor cable to the sensor marked connector. The stripping length is 7 mm.
   • The thermostat has spring connectors. Disconnected the conductors from the spring connectors by twisting and pulling at the same time.
   • Use a residual circuit breaker according to local installation regulations.

5. Install the thermostat into the mounting box with screws.

6. Install the thermostat lid, cover plate and adjustment knob. Cover the thermostat from potential dust during construction work.

Commissioning and operation, figure 3
