Outdoor ambient temperature
▪ In the outdoor unit, the outdoor ambient temperature is measured. Therefore,
the outdoor unit must be installed on a location:
- At the north side of the house or at the side of the house where the most heat
emitters are located
- That is NOT exposed to direct sunlight
▪ If this is NOT possible, we recommend to connect a remote outdoor sensor
(option EKRSCA1).
▪ Setup: For installation instructions, see the installation manual of the remote
outdoor sensor, and the addendum book for optional equipment.
▪ Configuration: Select outdoor sensor [9.B].
▪ When the power saving functionality of the outdoor unit is active (see "Power
saving function" [
4
226]), the outdoor unit is turned down to reduce standby
energy losses. As a result, the outdoor ambient temperature is NOT read out.
▪ 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.
