7.4 Temperature sensor

The following temperature sensors are already installed or must

be installed additionally:

Outside temperature sensor (R1) supplied (NTC-2)

Return temperature secondary circuit (R2) installed

(NTC-10)

Return temperature primary circuit (R24) installed (NTC-

10)

Flow temperature secondary circuit (R9) installed (NTC-10)

Flow temperature primary circuit (R6) installed (NTC-10)

7.4.1 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. 7.2 on page 6. The only exception is the outside

temperature sensor included in the scope of supply of the heat

pump (see Fig. 7.3 on page 6)

Fig. 7.3:Sensor characteristic curve NTC-2 according to DIN 44574 Out-

side temperature sensor

7.4.2 Mounting the outside temperature

sensor

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.

On the external wall of a heated room used as living space,

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

7.4.3 Installing the strap-on sensor

It is only necessary to mount the strap-on sensors if they are in-

cluded in the scope of supply of the heat pump but have not yet

been installed.

The strap-on sensors can be fitted as pipe-mounted sensors or

installed in the immersion sleeve of the compact manifold.

Mounting as a pipe-mounted sensor

Remove paint, rust and scale from heating pipe.

Coat the cleaned surface with heat transfer compound (ap-

ply sparingly).

Attach the sensor with a hose clip (tighten firmly, as loose

sensors can cause malfunctions) and thermally insulate.
