Mechanical Thermostat

This room thermostat is only used in heating systems to maintain the selected room temperature. If the room temperature falls below the selected setpoint, the heating contact will open. If the room temperature exceeds the selected setpoint, the heating contact will close.

Temperature control is based on internal sensor. An external sensor (SENSOR 10K ) can be connected without any additional external power supply.

Compatibles with both NC and NO actuators, such as Gas boiler or oil buners

Mounting, Installation and Commissioning

The room thermostat should be located where the air temperature can be sensed as  accurately as possible, without getting adversely affected by direct solar radiation or other heat or refrigeration sources. Mounting height is about 1.5 m above the floor.

The unit can be fitted to most commercially available recessed conduit boxes or directly on the wall. Only authorized personnel may open the unit to perform service. The unit must be isolated from the mains supply before opening. When installing the unit, first remove the cover of room thermostat, and then fix the thermostat body to wall. Then make the calibration as below. Use a sensible thermometer with this thermostat, in some atmosphere and be sure about the real temperature of room. Then remove plastic round cover of set point.

For example, the room temperature is 20 °C indicated on sensible thermometer. You must turn set point till you hear click voice. Then put the set point cover by matching 20 °C with arrow on cover of room thermostat. The thermostat must be mounted on a flat wall. The local electrical regulations must be complied with. If there are thermostatic radiator valves in the reference room, set them to their fully open position. The diaphragm is filled with environmentally friendly gas. The thermostat housing is made of plastic.
