6.7 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.

6.7.1 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.
