Victorum Combi
Overview
Connecting the Outdoor Sensor
The Outdoor Sensor monitors the outside air
temperature and is installed on the exterior of
the dwelling on a north facing wall, if possible.
Otherwise, the sensor must be kept away from
direct sunlight.
The exterior wall material must be considered,
as materials like Zinc can act as a heat sink.
This can affect the senor reading, producing
higher readings.
The outdoor sensor requires a two core
0.75mm2 cable and it is not polarity sensitive.
The sensor is connected to ‘B1’ and ‘Gnd’ on the
controller.
Connect the Positive (+) and Negative (-)
respecting the polarity at both the touchscreen
and transformer.
