Material damage
Protect the cables to the outdoor unit against UV
radiation. Use a UV-resistant cable or a cable in a
UV-resistant hose.
Material damage
Protect the cables to the outdoor unit against dam-
age from rodents.
8.4.9 Temperature sensor
Note
The maximum line length for sensor leads is 50 m.
Note
Sensor leads must be routed separately from 230 V
and 400 V cables. If a minimum distance of 20 cm
cannot be maintained, then shielded cables should
be used. The shielding should be connected to the
earth rail of the heat pump.
Outdoor temperature (T-AU):
»
Fit the outdoor temperature sensor to the outside wall
of the building (on the north-west side) at a height of
approx. 2.5 m. Make sure that the outdoor tempera-
ture sensor is not exposed to direct sunlight or wind,
as this will impair the control characteristics.
