Functional description
The controller compares the current room temperature with the setpoint temperature
and controls the heating and cooling devices according to the current demand. The
setpoint temperature is determined by the set operating mode and can be varied with
the adjustment dial (2). The selected operating mode and the current controller status
are indicated by the status LED (3) (see figure 1).
4 Operation
Operating modes and Status LED
Each heater requires a certain time to bring a cooled room to the desired temperat-
ure. For this reason, in the event of brief absence, the room temperature can be
lowered only slightly, e.g. by 2 K, and at night by somewhat more, e.g. 4 K. The con-
troller has various operating modes available for this.
