10.24.117 Alarm functions
10.24.118 Alarm functions - Condensate water alarm
Options: Deactivated
Activated
If a fan coil device is used, condensation may form during operation as a result of excessive
cooling and/or humidity. The associated condensate is typically collected in a container. To
protect the container against overflowing, and thus prevent potential damage to devices and/or
the building, the container alerts the "Condensation alarm" object (receiving only) that the
maximum fill level has been exceeded. This causes the controller to switch to a protective
mode. This is indicated by the corresponding icon on devices that have a display. Local
operation is blocked. Operation is only possible again after the alarm has been deactivated.
Notice
This parameter is only available when the "Control function" parameter is set
either on "Cooling," "Cooling with additional stage," "Heating and cooling" or
"Heating and cooling with additional stages".
10.24.119 Alarm functions — Dew point alarm
Options: Deactivated
Activated
When refrigerating machines are used, dew may appear on the refrigerant supply lines during
operation as a result of excessive cooling and/or humidity. The dew indicator signals the dew
formation via the "Dew point alarm" object (receiving only). This causes the controller to switch
to a protective mode. This is indicated by the corresponding icon on devices that have a display.
Local operation is blocked. Operation is only possible again after the alarm has been
deactivated.
Notice
This parameter is only available when the "Control function" parameter is set
either on "Cooling," "Cooling with additional stage," "Heating and cooling" or
"Heating and cooling with additional stages".
10.24.120 Alarm functions - Frost alarm temperature for HVAC and RHCC status (°C)
Options: Setting option between 0 - 20
The RHCC status and HVAC objects have a frost alarm bit. It the input temperature of the
controller drops below the temperature set in this parameter, then the frost alarm bit is set in the
status objects. It is reset when the temperature is exceeded.
