What is a heating circuit?

A heating circuit describes the circuit taken by the heating water from the boiler via the radiators and

back again. Multiple heating circuits can be connected to one boiler; for example, one heating circuit

for radiators and another heating circuit for underfloor heating. The radiators are supplied with a

higher flow temperature than the underfloor heating system. The flow temperature is the temperature

of the heating water generated by the boiler that flows into the heating circuit.

With the RC35 programming unit, you can operate and control multiple heating circuits [1]. In

addition to the RC35, a separate “remote control” (e.g. RC2x) can also be installed for additional

heating circuits [2]. A remote control is advisable if you want to control different heating systems

(e.g. radiators/underfloor heating) and/or different temperature levels.

1 Both heating circuits are controlled by one programming unit.

2 Each heating circuit has its own programming unit / remote control unit.
