control".
The following operating states may apply:

H Economy mode (reduced room temperature, e.g. night)

Based on the current operating status, certain components are either operational or non-operational, and the
nominal values which control the various functions change.
Room setpoint temperatures can be adjusted in the "Nominal values".
In some cases the reason for the current operating status is displayed, e.g. "flowtemp set point". The control
unit is in normal mode, as the "flowtemp set point" function is active.
