CONNECTION
6.1 General
The Remeha Selecta is equipped with an electronic control and safety unit incorporat-
ing ionisation-flame protection. The heart of the boiler control is a microprocessor, the
‘
abc
’-control, which both protects and controls the appliance.
6.1.1 Mains
voltage
The connection to the electricity main has to be made in accordance with the appropri-
ate regulations. The appliance is suitable for a 230V/50 Hz power supply, and is sup-
plied with a flying lead. This appliance should be fused at 3 A.
Note:
The boiler must have a permanent 230 volt power supply, which must not be
used to operate the boiler
6.1.2 Control
connections
All external control connections are made on the standard boiler connector
(X4, see
Fig. 16).
To gain access to this connector, remove the front of the boiler casing (
see
Par. 8.1, section 2
), lift and tilt the instrument panel down, making sure you engage
the 3 hooks on its base on the bottom of the case.
Fig. 19
shows the location of the
connector on the main pc board. The external connecting options are explained in the
following paragraphs.
Warning:
Under no circumstances should 230 volt connections be made directly on
to connector X4 as this will cause irreverseble damage to the electronic board. If 230
volts controls are required a simple relay kit is available from Broag,
see Par.3.4.
