HEATING CIRCUIT FLOW SENSOR B1
Mixing heating circuit flow sensor B1 is the control sensor of the
heating network. Sensor B1 is placed on the heating circuit out-
put line at a distance of approx. 1 m from the 3-way mixing
valve.
Connection, connector p, BX11/M
HEATING CIRCUIT FLOW SENSOR B12
Mixing heating circuit flow sensor B12 is the control sensor of
the heating network. Sensor B12 is placed on the heating circuit
output line at a distance of approx. 1 m from the 3-way mixing
valve.
Connection: Controller 2, connector p, BX11/M
If the first heating circuit (Heating circuit 1) of the heating sys-
tem is a pump heating circuit (i.e. not equipped with a 3-way
mixing valve), the flow sensor of Heating circuit 2 must be con-
nected to controller 1.
Connection: Controller 1, connector p, BX11/M
8.6 Connection of the domestic water
charging package (HWExE)
The domestic water charging package is connected to the GW
extension module (Domestic water). The domestic water charg-
ing package requires a circuit for hot water circulation. If the
heating system is not equipped for such a circuit, the jump wire
(H21/M) is to be replaced by a domestic water flow switch.

8.7 Connection of domestic water mixing
valve (HWEx)
The domestic water mixing valve is connected to the GW exten-
sion module (Domestic water). The domestic water mixing valve
requires a circuit for hot water circulation. If the heating system
is not equipped for such a circuit, the jump wire (H21/M) is to
be replaced by a domestic water flow switch.

8.8 Control of electric resistors in the ac-
cumulator / sequence controlled addi-
tional heating
The heat pump can be used for controlling electric resistors in
the accumulator or another sequence controlled heat source.
There are several different control modes for the electric resis-
tors. The electric resistors must be programmed site-specifically
according to the pertinent plant diagrams. For programming, see
section Site-specific definition / Programming of electric resis-
tors.
