Establishing the power supply
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 253 V, elec-
tronic components may be damaged.
▶
Make sure that the rated voltage of the
mains is 230 V.
≤ 30
mm
1.
Observe all valid regulations.
2.
Open the electronics box. (

3.
Set up a fixed connection and install a partition with
a contact gap of at least 3 mm (e.g. fuses or power
switches).
4.
Use a flexible line for the mains feed line, which is
routed through the grommet into the product.
5.
Carry out the wiring. (

5.6.4
Installing the product in protective area 1 or 2
Danger!
Risk of death from electric shock!
If you install the product in protective area 1
or 2 and you use the standard connection
cable with an earthed plug for this, there is a
risk of death from electric shock.
▶
Connect the product using a fixed connec-
tion and a partition with a contact open-
ing of at least 3 mm (e.g. fuses or power
switches).
▶
Use a flexible line for the mains feed line,
which is routed through the cable duct into
the product.
▶
Observe all valid regulations.
1.
If you install the product in protective area 2, it must be
operated as room-sealed. Installation method B53P is
not permitted in this case.
2.
Open the electronics box.
3.
The mains connection cable selected must meet the
requirements of the protective area.
4.
Carry out the wiring.
5.
Close the electronics box.

Conditions
: If you are connecting a weather-controlled
eBUS
controller or
a room-temperature-controlled
eBUS
controller:
▶
Connect the controller to the
BUS
plug.
▶
Bridge the plug
24 V = RT
if it has not been bridged
already.
Conditions
: If you are connecting a low-voltage controller (24 V):
▶
Connect the controller to the
24 V = RT
plug instead of
the bridge.
Conditions
: If you are connecting a safety thermostat for underfloor heat-
ing:
▶
Connect the thermostat to the
Burner off
plug instead of
the shunt.
3.
Close the electronics box.
4.
To trigger the
Comfort
pump operating mode (pump
