The heating circuit module allows for the
connection of a small, water-controlled
heating circuit (e.g. underfloor heating in
the bathroom, towel dryer, etc.) up to a max.
heat consumption of 500 watts. The mod-
ule is connected to the heating battery of
the service water tank. The room tempera-
ture sensor records the room temperature
in the area in which the heating circuit is
installed. For this room, an individual tem-
perature setpoint can be specified on the
control unit.
As an alternative, instead of the heating
circuit, an electrical additional heating (IR
panel, electric underfloor heating. electric
radiator, etc.) can also be activated via this
function by means of an external relay.
In the [settings] > [additional functions] the
heating circuit must be activated.
Observe the maximum electrical
load. Electric radiators must be
supplied and fused separately.
