FLOOR TEMPERATURE
The parameters for the floor temperature limit the floor temperature by means of maximum and
minimum thresholds. These thresholds interact with the set room temperature differently in heating
mode and cooling mode.
Heating mode
If the floor temperature falls below the minimum threshold min. Diff. on, heating mode will be
activated and cooling mode blocked regardless of the room temperature until the floor temperature
exceeds the threshold min. Diff. off (logical OR operation with the set room temperature for
heating).
If the floor temperature exceeds the maximum threshold max. Diff. off, heating mode will be
blocked and cooling mode activated regardless of the room temperature until the floor temperature
falls below the threshold max. Diff. on (logical AND operation with the set room temperature for
heating).
Cooling mode
If the floor temperature falls below the minimum threshold min. Diff. on, cooling mode will be
blocked and heating mode activated regardless of the room temperature until the floor temperature
exceeds the threshold min. Diff. off (logical AND operation with the set room temperature for
cooling).
If the floor temperature exceeds the maximum threshold max. Diff. off, cooling mode will be
activated and heating mode blocked regardless of the room temperature until the floor temperature
falls below the threshold max. Diff. on (logical OR operation with the set room temperature for
cooling).
N.B.: For cooling mode, the effective meaning of the terms Diff. on and Diff. off is the opposite of
their apparent meaning.
Parameters in the Average sub-menu
When outside temperatures form the basis of the shutdown conditions, fluctuations in those
temperatures can sometimes be undesirable. The option of adjusting the outside temperature is
therefore available for the purposes of shutdown. The following entries are found in this sub-menu:
