Procedure
1 Using the appropriate cable, connect the power circuit to the
main circuit breaker as shown on the wiring diagram and in
figure 2.
2 Connect the ground conductor (yellow/green) to the grounding
screw on the X1M terminal.
3 Fix the cable with cable ties to the cable tie mountings to ensure
strain relief. (Positions are marked with
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.

Power input selection to transformer TR2
This selection is needed to ensure a stable 24 V AC output.
Procedure
1 Measure main input power.
2 Reconnect wire according to the result of measurement.

Connection of the thermostat cable
Connection of the thermostat cable depends on the application.
See also "Typical application examples" on page 7 and "Room
thermostat installation configuration" on page 23 for more information
and configuration options on pump operation in combination with a
room thermostat.

Connect the thermostat cable to the appropriate terminals as
shown on the wiring diagram and installation manual of the room
thermostat kit.
Fix the cable with cable ties to the cable tie mountings to ensure
strain relief.
Set DIP switch SS2-3 on the PCB to ON. See "Room thermostat
installation configuration" on page 23 for more information.
Power supply: 24 V AC
Maximum running current: 100 mA
Using the appropriate cable, connect the valve control cable to
the X2M terminal as shown on the wiring diagram.
NOTE Wiring is different for a NC (normal closed) valve
and a NO (normal open) valve. Make sure to
connect to the correct terminal numbers as
detailed on the wiring diagram and illustrations
below.

Fix the cable(s) with cable ties to the cable tie mountings to
ensure strain relief.
Using the appropriate cable, connect the valve control cable to
the appropriate terminals as shown on the wiring diagram.
Two types of 3-way valves can be connected. Wiring
is different for each type:
"Spring return 2-wire" type 3-way valve
The 3-way valve should be fitted as such that
when the 3-way valve is idle (not activated), the
space heating circuit is selected.
"SPST 3-wire" type 3-way valve
The 3-way valve should be fitted as such that
when terminal ports 9 and 10 are electrified, the
domestic hot water circuit is selected.
