Condensate alarm active
Options: - Yes
- No
If the parameter "Condensate alarm active" is activated, the room
thermostat has a 1-bit communication object that can be used to send
telegrams from a container for condensate water. When an ON telegram
arrives, the room thermostat changes to the heat protection mode. Heat
protection is deactivated when an OFF telegram is received. This prevents
condensate, which can collect during cooling, from overflowing the
condensate container.
This parameter is only available if the "Cooling" or "Heat and cool" control
functions are used.
If a condensate collector alarm is detected, it is shown in the display
(fault symbol plus abbreviation).
The frost protection object is sent in the event of a condensate alarm if
the flag is set to send. If the condensate alarm is corrected and there is
no dewpoint alarm, the device switches from heat protection back to the
operating mode from the "operating mode after reset and Off" parameter.
Dew-point alarm active
Options: - Yes
- No
If the parameter "Dew-point alarm active" is activated, the room thermostat
has a 1-bit communication object that can be used to send telegrams from
a dew point sensor. When an ON telegram arrives, the room thermostat
changes to the heat protection mode. Heat protection is deactivated when
an OFF telegram is received. This prevents the condensate that forms
during incipient condensation when cooling is switched on from causing
damage.
This parameter is only available if the "Cooling" or "Heat and cool" control
functions are used.
If a dewpoint alarm is detected, it is shown in the display (fault symbol plus
abbreviation).
The frost protection object is sent in the event of a dewpoint alarm if the flag
is set to send. If the dewpoint alarm is corrected and there is no condensate
collector alarm, the device switches from heat protection back to the
operating mode from the "operating mode after reset and Off" parameter.
