9 Sensor equipment

The temperature sensor is preassembled on the fixed setpoint controller.
In inflow temperature control, assembly takes place on the inflow of the heating
cycle, in the in return flow temperature regulation it is assembled on the return
flow of the boiler. The recommended assembly location is approx. 0.5 m behind
the heating pump. The heating tube should be cleaned well and heat-conducting
paste should be applied during the assembly of the temperature sensor on the
heating pipe. Alternatively, the temperature sensor can also be used as an immer-
sion sensor.
