Temperature
setpoints
In automatic operating modes, temperature setpoints can be individually adjusted for
every comfort period and for the continuous operating modes. The temperature setpoint
of economy mode is the same in automatic and continuous operation.
Protective function
In the frost protection mode, the room temperature is constantly monitored. If it falls
below the adjusted setpoint, heating is switched on to maintain the adjusted frost pro-
tection setpoint temperature
.
24-hour operating
mode
The controller generates the 24-hour operating mode from the current 24-hour pro-
gram. It automatically selects the switch-on time of the first heating period and the
switch-off time of the last heating period to generate and display a complete heating
period. The comfort temperature used by the controller is the currently stored standard
setpoint of the continuous operating mode
. The self-generated 24-hour operating
mode is maintained until another operating mode is selected.
