10.5 Sensor installation
10.5.1 Contact sensor AVF 6 (included in the pack supplied)
 Connect an additional return sensor in combination with the
following heat pump types:
- WPL 13 E/cool
- WPL 18 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)
- WPL 07-17 ACS classic (only in combination with a buffer
cylinder)
Note
 For spread control and heat metering with the
WPL07-17ACSclassic in conjunction with the HM(S)
(Trend) hydraulic module, observe the operating and
installation instructions for this module.
For systems without a buffer cylinder
 Fit the sensor in the heating circuit return as a contact sensor
and if necessary, downstream of any overflow valve installed.
For systems with a buffer cylinder
 Fit the sensor as a return temperature sensor in the buffer
cylinder.
Installation:
The electrical connection is made at the user interface, specifically
at the “T/Buffer” terminal.
