a
Caution!
Material damage resulting from escaping
brine!
The screw couplings on the brine expan-
sion tank must be sealed with hemp.
Sealing with, e.g., seal can lead to leak-
age in the brine circuit.
• Fit the bracket for the brine expansion tank to the
wall using the wall plug and the screw.
• Unfasten the pre-assembled connection pieces from
the brine expansion tank (
57
).
• Wind hemp into the outer threads of the connection
pieces.
• Fit the first connection piece to the 3 bar expansion
relief valve (
42a
) enclosed with the heat pump.
• Using the second connection piece, fit the brine ex-
pansion tank (
57
) from the accessory kit to the pipe
(
1
) running from the heat source to the heat pump.
• Fix the brine expansion tank with the bracket.
• Fit the connection piece with the expansion relief
valve to the brine expansion tank.
• Fit the brine collecting tank (
65
) to the expansion re-
lief valve (
42a
) at zero pressure.
The brine collecting tank must not be completely
closed, as otherwise the functioning of the expansion
relief valve is not guaranteed.
• Provide all the pipes with vapour-proof thermal insula-
tion. The accessory kit contains the insulating mat
provided for the thermal insulation of the connection
plate.

Fitting the VRC DCF outside temperature
sensor
Fit the sensor in accordance with the enclosed installa-
tion instructions.
4.15
Fitting the VR 90 remote control unit
If you install several heating circuits, you can connect a
separate VR 90 remote control unit for each of the first
eight of them. It allows the operating mode and target
room temperature to be set, and takes into account the
actual room temperature measured by the built-in room
sensor, if necessary.
It is also possible to adjust the parameters for the asso-
ciated heating circuit (timer programme, heating curve
etc.) and to select the special functions (party, etc.).
In addition, it is possible to query the heating circuit and
to display service and fault messages.
For assembly of the VR 90 remote control unit, see its
enclosed installation instructions. Regarding installation
see Chapter 6.8.1.
4.16
Installing the VR 60 mixer module
With the mixer module, you can expand the control sys-
tem of the heating installation by two mixer circuits.
You can connect a maximum of six mixer modules.
A unique bus address is set on the mixer module by
means of a rotary switch. The setting of the heating
programme and all the required parameters is carried
out from the operating console. All heating circuit con-
nections (sensors and pumps) are made directly on the
mixer module using a ProE plug.
For assembly of the VR 60 mixer module, see its en-
closed installation instructions. Regarding installation
see Chapter 6.8.2.
