Proper heating and ventilation
Function of a thermostatic valve
The thermostat regulates the room temperature through the thermostatic valve. Level 3 corresponds approximately to a targeted room temperature of 20 degrees Celsius. The valve constantly compares the current room temperature (actual temperature) with the temperature set on the thermostat (target temperature). Differences are automatically adjusted. For example, if the room temperature is 14 degrees and the temperature setting on the thermostat is 20 degrees, the heating temperature is increased until the room has reached a temperature of 20 degrees.
Correct use of heating thermostats
Lowering the room temperature by just one degree can save around 6 percent of heating energy. For this reason, the thermostat should be set to a maximum level of 3. The room will not warm up any faster if level 5 is set. At level 5, the room temperature is instead increased up to 28 degrees Celsius in the most unfavourable scenario, which leads to overheated rooms and considerably higher energy consumption.
Ventilate properly and keep radiators clear
Office doors should generally be kept closed to avoid heating corridor areas unnecessary. For "shock ventilation", first turn the thermostat to the "star" or "snowflake" setting and then open the windows fully for 3 to 5 minutes. After closing the windows, the thermostat should be set to a maximum level of 3. Under no circumstances should ventilation be carried out with the windows tilted and/or the heating on. If ventilation is carried out with the heating on, the automatic control function would cause the thermostat to try to compensate the cold outside temperature reaching the valve and unnecessarily turn up the heating. In addition, the heat would escape directly through the open window instead of heating up the room. Radiators should not be blocked with furniture or covered with curtains, as this affects the thermostat function and hinders the heat circulation.
