Unlatching of the blind stop
– Remove the blind stop from the boiler control panel.
The blind stope is to be unlatched by means of a
screwdriver (see Fig. 4).
– The free cable end must be inserted into the control
panel through a vacant opening under the control
panel.
– The wires of the cable are to be connected in the
control panel to the free 5-pole terminal block (strip of
thermoplastic connectors) with the inscription KF.

control connection
(accessory)
Electrical connection between the controls and
boiler control panel:
The electrical connection between the controls and boiler
control panel is effected by means of the already installed
plug and cable. The codes on the plug will prevent the
positions from being interchanged when plugging in.
Subsequently the control unit is fitted in the slot of the
boiler control panel and attached with both fasteners by
means of a screwdriver.
In order to operate, turn the boiler temperature control
knob fully to the right up to the end stop and switch ”auto/
man/TÜV switch” in the auto-position.
For further information as regards the wiring please refer
to the installation manual of the respective
rapidomatic
®
control device.
The electrical connection to mains:
The electrical connection to the mains should be made
by means of the respective plugs on the rear of the
boiler. Viewed from the front of the boiler, the 230 V plugs
are located on the left hand side of the boiler rear cover,
the sensor plugs as well as a plug for the connection of a
motorised exhaust shutter (lower plug with the indication
MA) are located on the right hand side. It is
recommended first to disconnect one of the required
plugs (e.g. the mains plug) and connect each of the
cables in compliance with the plug description.
Subsequently the plug is reconnected. Then the wiring of
the next part (e.g. pump 1) is made, etc
