9.5 Characteristic curve
temperature sensor indoor unit
9.5.1 Sensor characteristic curves
The temperature sensors to be connected to the heat pump
manager must correspond to the sensor characteristic curve il-
lustrated in Fig. 9.1 on page 27. The only exception is the out-
side temperature sensor included in the scope of supply of the
heat pump (see Fig. 9.2 on page 27)
Fig. 9.1: Sensor characteristic curve NTC-10
Fig. 9.2: Sensor characteristic curve NTC-2 according to DIN 44574 Out-
side temperature sensor
9.5.2 Mounting the outside temperature
sensor
The outside temperature is measured via the heat source inlet
sensor on the outdoor unit. Optionally, a separate outdoor tem-
perature sensor can be mounted.
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.
Install on the external wall of a heated room, 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, ex-
ternal lighting or heat pumps
Not to be exposed to direct sunlight at any time of year
