Heat pump manager 7.2.4
7.2.2 Heat pump manager WPM 2007plus/ WPM EconPlus with removable control panel
All temperature sensors to be connected to the heat pump man-
ager with removable control panel must correspond to the sensor
characteristic curve shown in Fig. 7.6 on page 77. The only ex-
ception is the outside temperature sensor included in the scope
of supply of the heat pump (see Chapt. 7.2.3 on page 77)

7.2.3 Installing the external sensor
The external sensor must be mounted in such a way that all
weather conditions are taken into consideration and the meas-
ured 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
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
7.2.4 Installing the return sensor
It is only necessary to mount the return sensor if it is included in
the scope of supply of the heat pump, but is not integrated.
The return sensor can be fitted as a pipe-mounted sensor or in-
stalled in the immersion sleeve of the compact manifold or the
dual differential pressureless manifold.
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.
