Underfloor heating

In this configuration it is assumed that the
underfloor heating is controlled by the c-Mix.
You can also make the underfloor heating
autonomous — the c-Mix will only switch the
underfloor heating on and off.
4.3.7 Calorifier group with hot water circulation
pump
For this configuration, you can only connect 1
group to the c-Mix. Instead of group 1, the hot
water circulation pump is controlled for the DHW
standby function.
4.3.8 Connecting several c-Mix modules

- You can connect a maximum of four c-Mix
modules to each other thus enabling you to control
a maximum of eight central heating groups with a
single boiler.
- In this configuration, use the Remeha iSense as
the controller. This controller is able to control two
groups.
The OT2 input is used to connect the next c-Mix.
g
When using an external sensor, it must be
connected to the c-Mix that is directly connected to
the boiler. The external sensor on the boiler may
also be used.
