7.5 Temperature sensor

The following temperature sensors are already installed or must
be installed additionally:
 Outside temperature (R1; NTC-2) is supplied with the heat
pump manager.
 Secondary circuit return temperature (R2; NTC-10) in-
stalled
Flow rate monitoring (- R3.1; PT1000) installed

7.5.1 Sensor characteristic curves
The temperature sensors (NTC-10) to be connected to the heat
pump manager (controller -N1) must correspond to the sensor
characteristic curve illustrated in Fig. 7.8 on page 19. The only
exception is the outside temperature sensor included in the
scope of supply of the heat pump (NTC-2) (see Fig. 7.9 on
page 19)
