wards all information to the controllers. Vice versa,
the hot water, temperature and ECO settings are
forwarded to the boiler from controller 1 only.
5.5 hot water function of c-Mix
In order to prevent the jamming of valves and
pumps, these are switched on once per week for a
short period when they have not been in use for a
week. The boiler is not switched on here.
It is important with this control that the maximum
boiler temperature is at least 20°C higher than the
required hot water temperature. If this is not the
case, the calorifier may be unable to attain the
required hot water temperature.

short period when they have not been in use for a
