9.3 Operating modes in the heating circuit
9.3.1 Room operating modes
The room operating mode determines the state of a heated room. A differentiation is to
be made between preselected room operating mode and the state of the room
operating mode. Room operating mode
is only available as a preselection.
The user can preselect the following operating modes for space heating:
Preselection
Use
Auto Factory setting. The room operating mode changes
automatically according to the time program
Comfort The room is constantly maintained at the Comfort setpoint. This
operating mode is selected when the room is constantly
occupied
Precomfort The room is constantly maintained at the Precomfort setpoint.
This operating mode is selected when occupancy of the room
can be expected
Economy If the room is not used for a number of hours, or if a reduced
room temperature is desired, the recommended operating mode
is Economy.
Normally, this is the operating mode selected for the night
Protection In Protection mode, the room will be heated only when there is
risk of frost, causing water pipes to freeze, etc. The room
temperature will be maintained at a level above 0 °C
Depending on the state of the room operating mode, some other room temperature
setpoint will apply. The flow temperature setpoint, the heating limit and the optimization
functions will be influenced, depending on the current room temperature setpoint.
