Temperature sensors

The following temperature sensors are already installed or must be installed additionally:
• Outside temperature (R1; NTC-2), supplied with the heat pump manager
• Secondary circuit return temperature (R2; NTC-10), installed
• Flow rate monitoring (R3.1; PT1000), installed
7.3.1

Sensor characteristic curves

The temperature sensors (NTC-10) to be connected to the heat pump manager (controller -N1) must correspond to the
illustrated sensor characteristic curve
outside temperature sensor included in the scope of supply of the heat pump (NTC-2)
curve NTC-2 in accordance with DIN 50350 Outside temperature sensor, p. 27] .
