Operation and Control
By turning further to the right, parameters (temperature, humidity setpoints etc.) can be
selected as in the normal operating mode.
If no settings (temperature setpoint etc.) are made for the ON phase, the controller takes
over the values from the normal operating mode.
For reasons of safety, you should always check that a switch-on time is only programmed in
the desired time blocks and days.
If the controller is in standby mode or the week time switch is in the ON phase, the tempera-
ture setpoint can be directly accessed by briefly pressing the SET key. By turning the control
to the right, you get to the temperature monitoring, humidity and CO
2
settings. By turning to
the left, you can return to the settings for the individual time blocks.
