NOTE

For remote-reset, connect a push-button switch
(NO) between terminal 3 and neutral of the con-
trol box (terminals 15, 16, 17 and 18).

ELECTRICAL CONNECTIONS (B)

set by installer

All the wires to connect to the burner plugs 3)(B)
must be routed through the fairleads, supplied by
the manufacturer for insertion into the holes in
the plate, preferably those on the left side, after
having removed the thin diaphragm effectively
closing the aperture, as already explained
above.

down the burner when the boiler tempera-
ture or pressure exceeds the setpoint
value.

ates when TL is faulty.

NOTE

The RL 28/1 burner has been type-approved for
intermittent operation. This means it should
compulsorily be stopped at least once every 24
hours to enable the control box to check its own
efficiency at start-up. Burner halts are normally
provided for automatically by the boiler load
control system.
If this is not the case, a time switch should be fit-
ted in series to IN to provide for burner shut-
down at least once every 24 hours.

WARNING
Do not invert the neutral with the phase
wire in the electricity supply line.
