5.10.4 Installing the product in a wet room
Danger!
Risk of death from electric shock!
If you install the product in a room with high
levels of moisture, e.g. a bathroom, observe
the nationally recognised technical standards
for electrical installations. If you use the fact-
ory-installed connection cable, if installed,
with an earthed plug, there is a risk of death
from electric shock.
▶
Never use the factory-installed connection
cable with earthed plug when installing the
product in a moist environment.
▶
Connect the product using a fixed connec-
tion and an electrical partition with a con-
tact opening of at least 3 mm (e.g. fuses
or power switches).
▶
Use a flexible line for the mains connec-
tion line, which is routed through the cable
duct into the product.
1.
Open the electronics box. (

Page 14)
2.
Detach the ProE plug from the PCB slot for the mains
connection (X1).
3.
Unscrew the ProE plug for the factory-installed power
supply cable, if installed.
4.
Instead of the factory-installed power supply cable, if
installed, use a suitable three-core power supply cable
which complies with the relevant standards.
5.
Carry out the wiring. (

6.
Close the electronics box.
7.
Observe the flue-gas connection that is required on a
room-sealed air/flue system. (

5.10.5 Connecting controls to the electronics
1.
Install the control if necessary.
2.
Open the electronics box. (
→
Page 14)
3.
Connect the wiring in accordance with the wiring dia-
gram that is included in the appendix.
Conditions
: Connecting a weather-compensated control or room temperat-
ure control via eBUS
▶
Connect the control to the eBUS connection.
▶
Bridge the 24 V = RT connection (X100 or X106), if there
is not already a bridge.
Conditions
: Connecting a low-voltage control (24 V)
▶
Remove the bridge and connect the control to the
24 V = RT connection (X100 or X106).
Conditions
: Connecting a limit thermostat to underfloor heating
▶
Remove the bridge and connect the limit thermostat to
the "Burner off" connection.
4.
Close the electronics box.
5.
For multi-circuit controls, change
D.018
from
Eco
(in-
termittently operating pump) to
Comfort
(continuously
operating pump), see section "Adapting to the heating
installation".
5.10.6 Connecting the communication unit
The product can be connected to the Internet.
▶
Connect the communication unit in accordance with the
installation instructions enclosed with the communication
unit.
5.10.7 Replacing the gas family coding resistor, if
required
1.

2.
Remove the gas family coding resistor
(1)
(plug X24)
(factory setting: natural gas = yellow) and plug in the
coding resistor from the bag of small parts (liquefied
petroleum gas = grey).
3.
Close the electronics box.
4.
When starting up in the installation assistant or retro-
actively via diagnostics code
D.087
, set the correct gas
type.
5.10.8 Connecting additional components
You can actuate an additional component with the aid of the
auxiliary relay that is installed, and you can actuate two other
components with the multi-functional module.
5.10.8.1 Using the auxiliary relay
1.
Connect an additional component directly to the integ-
rated auxiliary relay using the grey plug on the PCB.
2.
Carry out the wiring.
3.
Activate the component via
D.026
, see section "Adapt-
ing to the heating installation".
5.10.8.2 Using the VR 40 ("2 in 7" multi-functional
module)
1.
Install the components in accordance with the respect-
ive instructions.
Conditions
: Components connected to relay 1
▶
Activate
D.027
, see section "Adapting to the heating
installation".
Conditions
: Components connected to relay 2
▶
Activate
D.028
, see section "Adapting to the heating
installation".
