The feeder module supplies the heating and
cooling distributors.

tures can be set up easily. It is also easy to operate several
heating circuits with different transfer capacities for heatings, underfloor and wall heatings or hot water systems in
Direct heating circuit modules D/D.plus
These preset modules are perfect to supply the
heating. The flow temperature of the heating
circuit is determined by the flow temperature
of the feeder module. The direct heating circuit
module is available in two versions, i.e. D and
D.plus.

Mixer heating circuit modules M/M.plus
These regulated modules are perfect to supply both heating and hot water systems. The
flow temperature is regulated by a 3-way valve.
Therefore, an individual flow temperature can
be set.
For instance, a low flow temperature is necessary for the operation of an underfloor heating.
The mixer heating circuit module is available in
two versions, i.e. M and M.plus.
