The boiler is provides with an input for a 0–10 V DC signal to control the
boiler temperature or the boiler output directly.
– To activate this function, set param. 618 to 4 or 5 (see table 7 for details)
– For a proper use of this input, disconnect all external controls from the
boiler (e.g. room control RRG) and set the heating curves to "1"
(parameters 532 and 533, see tab. 7).
Note: If any other relay module (e.g. CIST, CIR, CITF) is installed, the
CISP must be taken out!
It is essential to clean the boiler, heat exchanger and burner once a year by
an approved gas installer. The need to clean the boiler and burner can also
be indicated by a CO emission value that exceeds 200 ppm. Before starting
work, the gas valve must be closed and the electricity to the boiler turned
off.
The condensate siphon should be cleaned every one or two years. To do
this the upper screw connection on the siphon is loosened and the siphon is
pulled away downwards. Remove the siphon completely with hose from
the boiler, disconnect and rinse through with clean water. Re-assemble the
siphon in reverse order.
Remove the gas burner before cleaning the heating surfaces. To do this
disconnect the electrical wiring to the fan from the terminals and pull the
hose of the air pressure from the fan.
G Unscrew the screw connection of the gas supply pipe in front of the gas
solenoid.
G Pull off electrical wires and plugs from the gas solenoid, gas pressure
switch, ignition electrodes as well as the ionization electrode
G Loosen securing nuts of the burner (SW13) and pull out the burner
complete with mixing chamber, fan and gas solenoid forwards
G Clean burner pipes with soft brush.
