1
Using the appropriate cable, connect the power circuit to the
main circuit breaker as shown on the wiring diagrams (inside of
door 2) and in
figure 2
.
2
Connect the earth conductor (yellow/green) to the earthing
screw next to the X10M terminal.
3
Fix the cable with cable ties to the cable tie mountings to ensure
strain relief. (Positions are marked with
in
figure 2
.)
Note: only relevant field wiring is shown.
4
If the backup heater capacity is to be set lower than the default
value (6 kW), this can be done by reconnecting wires according
to following figure. The backup heater capacity is now 3 kW for
V3 models or 2 kW for W1 models.
Connection of the thermostat cable
Connection of the thermostat cable depends on the application.

for
more information and configuration options on pump operation in
combination with a room thermostat.
Thermostat requirements
■
Power supply: 230 V AC or battery operated
■
Contact voltage: 230 V.
Procedure
1
Connect the thermostat cable to the appropriate terminals as
shown on the wiring diagram and installation manual of the room
thermostat kit.
2
Fix the cable with cable ties to the cable tie mountings to ensure
strain relief.
3
Set DIP switch SS2-3 on the PCB to ON. See
"10.2. Room
thermostat installation configuration" on page
29
for more
information.
Connection of the first set point and second set point contacts
The connection of the set point contact is only relevant in case dual
set point contact is enabled.
See also
"3.4. Typical application examples" on page 4
and
"Dual set
point control" on page 39
.
Contact requirements
The contact shall be a voltage free contact that ensure 230 V
(100 mA).
Procedure
1
Connect the contact of first set point and second set point to the
appropriate terminals as shown in the figure below
2
Fix the cables with cable ties to the cable tie mountings to
ensure strain relief.
3
Depending on the required pump operation set DIP switch
SS2-3 and field setting [F-00]. See
"10.3. Pump operation
configuration" on page 29
and field setting [F-00] in
"[F] Option
setup" on page 43
