Output variables
Effective set room temp.
The effective (=current) set temperature as defaulted by the input
variable + Offset value or by frost protection mode.
Heating
Status ON if heating mode is active.
Cooling
Status ON if cooling mode is active.
Open valve
Status ON if heating or cooling mode is active.
Close valve
Status ON if neither heating nor cooling mode is active.
Frost protection mode
Status ON if the room temperature is below T.room frost.
T.room < T.room set
(heating)
Status ON if the actual room temperature is lower than the set room
temperature + Offset value + Diff.
T.room > T.room set
(cooling)
Status ON if the actual room temperature is higher than the set room
temperature + Offset value + Diff.
T.floor < set max.
(heating)
Status ON if the actual floor temperature is lower than the set floor
temperature + Floor max. Diff.
T.floor < set min. (heating)
Status ON if the actual floor temperature is lower than the set floor
temperature + Floor min. Diff.
T.floor > set max. (cooling)
Status ON if the actual floor temperature is higher than the set floor
temperature + Floor max. Diff.
T.floor > set min. (cooling)
Status ON if the actual floor temperature is higher than the set floor
temperature + Floor min. Diff.
Aver.off < max. heating
Status ON if the condition is met (including + Diff.).
Aver.off > min. cooling
Status ON if the condition is met (including + Diff.).
Aver. OT for shutdown
The adjusted outside temperature
Heating delay
Display of a countdown of the delay for changeover to heating mode
Cooling delay
Display of a countdown of the delay for changeover to cooling mode
➢ There are different output variables for Heating, Cooling, Open valve and Close valve.
Which ones are used depends on the hydraulic conditions of the system.
➢ If enable = Off, all statuses are set to OFF.
➢ If enable heating = Off, the frost protection function is deactivated as well.
