4.3.9 Mixing groups with a direct group heated at
high temperature
In this configuration, the first controller controls
groups 1 and 2. The second controller only sends
a heat requirement to the boiler, but does not
control a valve or group pump.

4.3.10 Floor heating with direct radiator group

In this configuration the controller controls groups
1 and 2. Here, group 2 is the radiator group that
does not have a valve. This means that the
radiators will also heat up when the floor heating
is on. This can be desirable depending on the
system. For group 2 choose rotary switch position
4. (see para. 4.7.9)

4.3.11 Cascade configuration with two mixing groups

In this configuration, the CelciaMC4 (or RemticMC)
controls both boilers. It uses the central heating
temperature it receives from the c-Mix. This
ensures the control of the groups. The calorifier is
controlled by the DHW regulation of the boiler.
