12.1 Sensor installation

12.1.1 Contact sensor AVF 6 (included in the pack supplied)

f Connect an additional return sensor in combination with the f
following heat pump types:
- WPL 13 E/cool
- WPL 10 I
- WPL 10 AC(S)
- WPL 15-25 AC(S) (only in combination with a buffer cylinder)
- WPL 08-22 (S) Trend (only in combination with a buffer
cylinder)
For systems without a buffer cylinder
f Fit the sensor in the heating circuit return as a contact sensor f
and if necessary, downstream of any overflow valve installed.
For systems with a buffer cylinder
f Fit the sensor as a return temperature sensor in the buffer f
cylinder.
Installation:
The electrical connection is made at the user interface, specifically
at the "T/Buffer" terminal.
f Clean the pipe. f
f Apply heat conducting paste. f
f Secure the sensor with a cable tie. f
12.1.2 Outside temperature sensor AFS 2 (included in the pack
supplied)
The temperature sensors have a significant influence on the func-
tion of your heating system. Therefore ensure sensors are correctly
positioned and well insulated.

f Install the outside temperature sensor on a north or f
north-eastern wall. Minimum clearances: 2.5 m above the
ground, and 1 m to the side of windows and doors. The
outside temperature sensor should be freely exposed to the
elements but not placed in direct sunlight.
f Never mount the outside temperature sensor above win- f
dows, doors or air ducts.
