The temperature sensors to be connected to the heat pump man-
ager must correspond to the sensor characteristic curve illus-
trated in Fig.9.1 on pag. 17. The only exception is the outdoor
temperature sensor included in the scope of supply of the heat
pump (see Fig.9.2 on pag. 17)

DIN 44574
Outdoor temperature sensor
9.5.2 Mounting the outdoor temperature
sensor
The temperature sensor must be mounted in such a way that all
weather conditions are taken into consideration and the meas-
ured value is not falsified.
On the external wall of a heated room used as living space,
if possible on the north or north-west side of the building
Do not install in a "sheltered position" (e.g. in a wall niche or
under a balcony)
Not in the vicinity of windows, doors, exhaust air vents,
external lighting or heat pumps
Not to be exposed to direct sunlight at any time of year
Sensor lead: Max. length 40 m; min. core cross-section
0.75 mm²; external diameter of the cable 4-8 mm.
