Mains supply 230V
Cable grip
Protect all cables against strain
with the enclosed cable grips
when the controller is folded
open.

Controller modules are only connected
with 3 lines (no +) of the bus system.
Control modules are connected with 4 li-
nes because these have to be supplied.
4.5.1 Safety measures relating to EMC assembly
1.
For regulator units with their own power supply, sepa
-
rate laying of power leads and sensor or bus-leads is
absolutely essential. If using cable channelling, only
that fitted with separator strips may be used.
2.
The mains connection for the heating system (boi
-
ler control panel regulator unit) must be designed as
an independent electrical circuit. Neither fluorescent
lamps nor any other equipment which might cause in
-
terference may be connected, nor may it be possible
to connect such equipment.
Fuse
Boiler room
emergency switch
Heat generator
Boiler room lighting and pwer
sockets must be in a separate
circuit
3.
The fresh air sensor must not be fitted in the vicinity
of transmitters and receivers (on garage walls near
receivers for garage door openers, amateur radio an
-
tennae, radio alarm installations or in the immediate
vicinity of transmitters etc.
Recommended cable cross-sections and maximum
permitted cable lengths:
Cables carrying mains supply voltages from actuators:
(burner, pumps, actuators etc.): min. 1mm
2
Maximum permissible length:
no restrictions, within the framework of the building’s in
-
ternal installations.
Sensor cables and cables carrying low voltages:
minimum 0.5 mm
2
Maximum permissible cable length: 50 m
Data bus lines:
4-wire bus, twisted, shielded, minimum 0.5 mm
2
Maximum permissible cable length: 100 m
