5.4.3
Carrying out the wiring
Caution.
Risk of material damage caused by incor-
rect installation.
Mains voltage at the incorrect plug terminals
on the ProE system may destroy the elec-
tronics.
▶
Do not connect any mains voltage to the
eBUS terminals (+/-).
▶
Only connect the mains connection cable
to the terminals marked for the purpose.
1.
Route the supply lines of the components to be connec-
ted through the cable duct provided on the underside of
the product.
2.
Use the strain reliefs provided.
3.
Shorten the supply lines as necessary.
4.
To prevent short circuits if a strand accidentally comes
loose, only strip the outer sheathing of flexible lines to a
maximum of 30 mm.
5.
Ensure the inner conductor insulation is not damaged
when stripping the outer sheathing.
6.
Only strip inner conductors just enough to establish
good, sound connections.
7.
To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
8.
Screw the respective ProE plug to the supply line.
9.
Check whether all conductors are sitting mechanically
securely in the terminals of the ProE plug. Remedy this
if necessary.
10. Plug the ProE plug into the associated PCB slot.
11. Secure the cable in the electronics box using the strain
reliefs.

3.
Use the strain reliefs provided.
4.
Plug the ProE plug for the mains power cable into slot
X18.
5.
Plug the ProE plug for the control cable into slot X22.
6.

Installing the controller
▶
Install the controller if necessary.
5.4.6
Connecting controllers to the electronic
system
1.
Open the electronics box. (

2.
Carry out the wiring. (

3.
If you connect a weather compensator or room thermo-
stat to the product via eBUS, bridge the input 24 V = RT
(X100 or X106) if no bridge exists.
4.
If you use a low-voltage controller (24 V), connect this
instead of the bridge 24 V = RT (X100 or X106).
5.
When connecting a maximum thermostat (contact ther-
mostat) for underfloor heating, connect this instead of
the bridge (Burner off) at the ProE plug.
6.
Close the electronics box. (

7.
In order to achieve the
Comfort
pump operating mode
(continuously running pump) for multi-circuit controllers,
change D.018 Pump operating mode (
→
Page 25) from
Eco
(intermittent pump) to
Comfort
.
8.
If a system separation is installed, set the pump to
Comfort D.018
and set the pump output to at least
4 (85%,
D.014
). This also applies for installing in
cascade.
