▪ If the desired leaving water temperature is weather dependent, the full time
outdoor temperature measurement is important. This is another reason to install
the optional outdoor ambient temperature sensor.
INFORMATION
The external outdoor ambient sensor data (either averaged or instantaneous) is used
in the weather-dependent control curves and in the automatic heating/cooling
changeover logic. To protect the outdoor unit, the internal sensor of the outdoor unit
is always used.
