⇒
Remove the front panel from the boiler.
⇒
Carefully push the control (without wall socket, see
Fig. 4.1) with the pin rail into the plug connector on
the boiler.
⇒
Now fit the outside sensor (see Chapter 4.6).

5 Terminals for eBUS line and plug connection for pin rail
This is how to do it:
⇒
Pull the controller (
1
) off the wall socket (
2
). This
can be done by pushing a screwdriver into the two
retaining straps (see Fig. 4.1 arrows).
⇒
Mark the position on the wall. Observe the cable run
of the eBUS line when doing so.
⇒
Drill two holes 6 mm diameter to suit the fixing
apertures (
3
).
⇒
Insert the plugs supplied.
⇒
Insert the eBUS cable through the cable entry
apertures (
4
).
⇒
Use the screws supplied to fix the wall socket.
⇒
The electrical installation is carried out as
described in Chapter 5.1.
⇒
Carefully push the controller onto the wall socket
until it clicks in position. The pin rail on the back of
the controller must fit into the plug connector (

Fitting the outside sensor
The location of the outside sensor should meet the
following conditions:
– no especially carefully wind-protected location
– no particularly draughty location
– no direct sunlight
– no influence from heat sources
– N or NW facing facade
On buildings with up to 3 floors, the outside sensor
should be fitted at the 2/3 floor facade height, on
buildings with more than 3 floors, mount between the
2nd. and 3rd. floor.
a
Caution!
Dampness in the wall and in the unit!
Incorrect installation can lead to damage to the
unit and/or the wall of the building.
Observe the cable routing described and the
correct installation position of the outside
sensor.
h
Note!
The steps for installation are the same for both
outside sensors, with the following exceptions:
–
the VRC 693 requires a twin-core
connection cable
–
the VRC 9535 requires a 3-core
connection cable
