Room temperature
The current room temp, from the internal or the external sensor.
11
Change-over temperature or fan release temperature
The current change-over temperature. Shows NaN! if no sensor is connected.
20
Room temperature (internal)
The value from the internal temperature sensor.
21
Room temperature (external)
The value from the external temperature sensor. Shows a value if a temperature sensor is
configured for Temp/AI, NaN! otherwise.
22
The value from the external change-over temperature sensor. Shows a value if a change-
over sensor is configured for Temp/AI, NaN! otherwise.
25
AI Temp Raw
Raw value of the terminal (before any filters). Shows NaN! if no sensor is connected.
27
AI Temp
Value of the Analog input after filters and scaling. Shows NaN! if no sensor is connected.
