Window status:
The room temperature controller provides different ways of switching into the frost/heat protection . Besides
switching by means of the corresponding operating mode switch-over object, the frost/heat protection can be
activated by a window contact. Among these options, the window contact has the higher priority.
A telegram with the value = "1" (opened window) to object 34 will activate the frost/heat protection. In this case the
operating mode cannot be deactivated by the operating mode switch-over objects (with the exception of the
KONNEX forced-control object).
Only a telegram with the value = "0" (closed window) will reset the window status and deactivate the frost/heat
protection. Subsequently, the operating mode that was set before the opening of the window or tracked via the
bus during the time the window was open will be activated.
Operating mode after reset:
In the ETS it is possible to determine via the "Operating mode after reset" parameter on the "Controller General"
parameter page which operating mode is to be activated following a return of bus voltage or a programming
operation with the ETS. The following settings are possible:
- "Comfort mode":
- "Standby mode":
- "Night mode":
- "Frost/heat protection":
- Restore operating mode before reset":
The objects associated with the activated operating mode will be updated after a reset.
