Temperature PI control
For an adequate regulation of the indoor temperature, comfort, standby, eco and build-
ing protection modes may be used.
Comfort
when present,
Standby
during short absences,
Eco
as a night-time mode and
Frost/heat protection
(building protection) during longer absences.
The settings for the temperature control include the set point temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).
The
mode
may be switched with two 8 bit objects of different priority. Objects
"... HVAC mode (Prio 2)" for switching in everyday operation and
"... HVAC mode (Prio 1)" for central switching with higher priority.
The objects are coded as follows:
Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others are used to activate comfort mode or frost/heat pro-
tection mode. The comfort object then blocks the eco/standby object, and frost/heat
protection objects have the highest priority. Objects
"... Mode (1: Eco, 0: Standby)",
"... comfort activation mode" and
"... frost/heat protection activation mode"
Select the mode to be activated after reset (e.g. power failure, reset of the line via the
bus). (Default).
Then configure a block of the temperature control by the blocking object.
