General
This accessory is used when
F1145/F1155/F1245/F1255/F1345/F370/F470/F750/VVM
310/VVM 320/VVM 500/SMO40 is installed in houses
with up to four different climate systems that require
different flow line temperatures, for example, in cases
where the house has both a radiator system and an
under floor heating system.
The water flow in the climate systems together should
not exceed 1700 l/h.
Caution
Underfloor heating systems are normally max
flow line temperature set between 35 and 45
°C.
Check the max temperature for your floor with
your floor supplier.
Caution
If the room sensor is used in a room with under
floor heating it should only have an indicatory
function, not control of the room temperature.

Pipe connections
General
When connecting extra climate systems, they must be
connected so that they have a lower working temper-
ature than the climate system 1.
Circulation pump and mixing valve
The extra circulation pump (GP20) is positioned in the
extra climate system according to the outline diagram.
F1145/F1155/F1245/F1255/F1345/F750/
VVM310/VVM320/VM500/SMO40
႑The mixing valve (QN25) is located on the flow line
after the heat pump/indoor module, before the first
radiator in the climate system 1. The return line from
the additional climate system must be connected to
the shunt valve and to the return line from the heat-
ing system 1, see image and outline diagram.
F370/F470
႑First drain the boiler water reservoir/heating system
if filled with water.
႑Unscrew the plugged connection that is on the
docking connection (XL8).
႑Install the supplied plastic pipe with coupling in the
docking connection (XL8).
႑The mixing valve (QN25) is located on the flow line
after the heat pump from its docking connection
(XL8). The return line from the extra climate system
is connected to the mixing valve and to the return
line from the heating system 1, see image and outline
diagram.
NOTE
Incorrect installation can affect the function.

Temperature sensor
႑The flow temperature sensor (BT2) is installed on the
pipe between the circulation pump (GP20) and mix-
ing valve (QN25).
႑The return line sensor (BT3) is installed on the pipe
from the extra climate system.
K
Install the temperature sensors with cable ties with the
heat conducting paste and aluminium tape. Then insu-
late with supplied insulation tape.
NOTE
Sensor and communication cables must not
be placed near power cables.

Electrical connection
NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be car-
ried out in accordance with the stipulations in
force.

powered when installing ECS 40/ECS 41.
The electrical circuit diagram is at the end of this In-
staller handbook.
Connecting communication
Ground-source heat pumps
This accessory contains an accessory card (AA5) that
must be connected directly to the heat pump on the
input card (terminal blockAA3-X4) in
F1145/F1155/F1245/F1255 or on terminal block X6
in F1345.
If several accessories are to be connected or are already
installed, the following instructions must be followed.
The first accessory card must be connected directly to
the input card's terminal block (AA3-X4) in
F1145/F1155/F1245/F1255 or on terminal block X6
on F1345. The following cards must be connected in
series with the previous card.
