4.5.4 Buttons 3/4
This pair of buttons is permanently preset to "
temperature shift
" and cannot be used for any other
purpose. Depending on the use of the internal temperature controller (as "Controller" or "Extension
unit"), there are differences in the settings.

–
Temperature shift as a controller
If the temperature controller is selected as "Controller", the setting "Setpoints for Standby/Night"
has an effect on the type of temperature shift for buttons 3/4.
Important:
The temperature shift refers to the controller in the unit. There are no communication
objects for the buttons 3/4.

Buttons 3/4: Temperature shift as controller (1)
Functional principle:
This function shifts the current setpoint within the set limits. When the “
-
“ button is pressed, the
setpoint is sent
subtracted from the last value by the set increment, and when the “+” button is
pressed, it is sent added to the last value by the set increment.
