Wiring the controller PCB
The controller has an automatic sensor recognition
function. You must configure the connected heating cir-
cuits in accordance with the system combination. In the
following you will find various options for operating the
heat pump.
6.6.1
Connecting the VR 10 standard sensor
Additional sensors are required as flow, return, collector
or cylinder sensors, depending on the configuration of
the system. The VR 10 standard sensor is so designed
that it can be used as an immersion sensor, e.g. as a cyl-
inder sensor in a cylinder sensor tube, or as a flow sen-
sor in a hydraulic switch. Using the enclosed cable tie
you can also attach it as a contact sensor to the heating
flow or return pipes. We recommend that the pipe to-
gether with the sensor be insulated to ensure optimum
temperature measurement.

6.6.2 Shutting out of the heating circuit from the
cooling operation
You can activate the stop valves to the heating circuits
which should be excluded from the cooling operation
(e.g. bath) via the connection terminal "SK2-P" (see
Fig. 6.7, item

).
