Here the system heats to the set night temperature in setback
heating mode.
The heating circuit pumps operate constantly.
The heating program is only switched on in automatic mode; night
setback is not available in manual mode.
2.5 What are heating circuits?
A heating circuit describes the circuit taken by the heating water
from the boiler via the radiators and back to the boiler (Fig. 1 on
page 5). Several heating circuits may be connected to one boiler,
for example one heating circuit for supplying radiators and a further
heating circuit for supplying an underfloor heating system. In this
case, the radiators are supplied at a higher flow temperature than
the underfloor heating system.
With the RC30 you can operate and control the two heating circuits
independently (Fig. 2, Item 1). If the second heating circuit is used
to supply a separate flat or area of the building, a separate room
controller RC20 can also be installed (Fig. 2, Item 2). This allows
you to operate the second heating circuit as an "independent"
system.

heating circuits (1) or RC30 plus RC20 as a remote control for
