Connecting the pump group to the PCB
>
Guide the pump cable for the pump group through the
cable duct to the right on the underside of the unit.
>
Uses the strain reliefs provided.
>
Connect the power supply network plug of the pump
group to the X18 slot on the PCB (
¬ fig. 8.3
).
>
Connect the control cable of the pump group to the X22
slot on the PCB (
¬ fig. 8.3
).
>
Lay the lines correctly.
>
Secure the lines using the strain reliefs in the electronics
box.
>
Close the electronics box (
¬ section 8.2
).
i
Ensure that the connection cables are securely
fastened to the plug terminals.

Connecting the controller
8.4.1
Fitting the controller
>
Fit the controller in accordance with the respective
installation instructions.
8.4.2 Connecting controllers to the electronic
system
b
Caution.
Risk of damage caused by incorrect
installation.
Connecting wires that have been stripped
too far may cause short circuits and dam-
age the electronics if a strand accidentally
comes loose.
>
Only strip the lines a maximum of 3 cm
to prevent short circuits.
>
Lay the lines correctly.
>
Use strain reliefs.
b
Caution.
Risk of material damage caused by incor-
rect installation.
Mains voltage at the incorrect plug termi-
nals on the ProE system may destroy the
electronics.
>
Do not connect a mains voltage to the
eBUS terminals (+/-).
i
Make sure that the conductors are securely fas-
tened to the plug terminals of the ProE plug.
>
Open the electronics box (
¬ section 8.2
).
>
Guide the supply lines of the components to be con-
nected (e.g. external controller, external sensor) through
the cable duct to the left on the underside of the unit.
>
Insert the supply lines into the electronics box.
>
Uses the strain reliefs provided.
>
Shorten the supply lines as necessary.
>
Strip the supply lines 2 - 3 cm, but not more than 3 cm.
>
Strip the conductor on the supply lines.
>
Fit conductor end sleeves on the stripped ends of the
conductors.
>
Connect the ProE plug to the supply lines of the control-
ler using a screwdriver.
>
Insert the ProE plug into the associated PCB slot
(
¬ fig. 8.4
).
>
Lay the lines correctly.
>
Secure the cable in the electronics box using the strain
reliefs.
>
If you do
not
connect a room/timer thermostat to the
boiler, bridge the input RT 24 V if no bridge exists.
>
If you connect
a
room/timer thermostat to the boiler,
remove the bridge at input RT 24 V, if a bridge exists.
>
If you connect a weather-controlled compensator or
room temperature control system via eBUS, then bridge
input RT 24 V, if no bridge exists.
>
Close the electronics box (
¬ section 8.2
).
