3.2 Temperature sensor (heating controller N16)
All temperature sensors to be connected to the heat pump
controller have the sensor characteristic curve illustrated in Fig.
3.3 on p. 3. The only exception is the external temperature
sensor included in the scope of supply of the heat pump (see
Chap. 3.2.1 on p. 3) It matches the NTC2 sensor characteristic
curve.
Depending on the connection type, the following additional
temperature sensors must be installed:
External temperature sensor (Chap. 3.2.1 on p. 3)
Regulation sensor for flow temperature (mixer circuit)
Hot water temperature sensor
Room climate control system for temperature and humidity
measurement

3.2.1 Mounting the external temperature sensor
The temperature sensor must be mounted so that all weather
conditions are taken into consideration and the measured value
is not falsified.
Installation:
On the external wall of a heated room used as living space,
if possible on the north or north-west side of the building
Not in a “sheltered position” (e.g. in a wall recess 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 15 m; min. core cross section
0.75 mm²; outer diameter of the cable 4-8 mm.

mounting
3.2.2 Mounting of the sensor for the mixed heating circuit
Mounting of the sensor for the mixed heating circuit is only
required if a second heating circuit is operated with a mixer, or if
the “silent cooling” cooling function is used.
The regulating sensor can be installed as pipe-mounted sensor.
Remove paint, rust and scale from heating pipe.
Coat cleaned surface with heat transfer compound (apply
sparingly).
Attach sensor with hose clip (tighten firmly as loose sensors
can cause malfunctions) and thermally insulate.
