Installation 3.2
3.2 Temperature Sensor (Heating Controller N1)
Depending on the type of heat pump implemented, the following
temperature sensors are already installed or must be additionally
mounted:
External temperature sensor (R1) (see Chap. 3.2.3 on p. 6)
Temperature sensor for heating circuit 1, 2 and 3 (R2, R5
and R13)
(see Chap. 3.2.4 on p. 6)
Flow temperature sensor (R9), used as flow sensor for air-
to-water heat pumps
Outlet temperature sensor for the heat source in the case of
brine-to-water and water-to-water heat pumps
Hot water temperature sensor (R3)
Temperature sensor for the regenerative heat accumulator
(R13)
The heating controller N1 is available in 2 versions:
Heating controller with integrated display (WPM 2006)
(see Chap. 3.2.1 on p. 5)
Heating controller with removable operating element
(WPM 2007)
(see Chap. 3.2.2 on p. 5)
3.2.1 Heating Controller with Integrated Display (WPM 2006)
All temperature sensors to be connected to the heating controller
with integrated display must correspond to the sensor
characteristic curve shown in Fig. 3.3 on p. 5.

44574 for connecting temperature sensors to the heating controller
with integrated display
3.2.2 Heating controller with removable operating element (WPM 2007)
All temperature sensors to be connected to the heating controller
with removable display must correspond to the sensor
characteristic curve shown in Fig. 3.5 on p. 5. The only exception
is the external temperature sensor included in the scope of
supply of the heat pump (see Chap. 3.2.3 on p. 6)
