Calibrating
When indoor temperature reaches steady state, user could calibrate the heating thermostat to make the temperature reading be the same as the real room temperature.
Restriction of Control Knob Adjusting Range
The lock mechanism under the controlknob can be used to restrict the adjusting temperature range. User can lock the adjusting range (e.g.20-25℃) as long as loosing the screw C (shown in Fig.2).
Mounting of Outer Sensor
Please place the casing under the floor with the outer sensor in, the terminal of which should be thickened and placed on the top of the concrete layer. Sensor cable can be extended to 50m with other cables if necessary. If multi-core cable is used as extended cable, extra cable core should not be used for power supply (e.g. power supply for heating cable) for avoiding the interference of voltage signal to the heating thermostat. If there is shielded cable in the extended cable, shielded cable should not be connected to ground but to terminal 7. It is recommended that the extended cable and casing should not be shared with others.
