Directions for use
•
Automatic controls are safety devices and shall not be
opened. The manufacturer’s responsibility and guarantee
are invalid if the control is unduly opened.
•
A regulation shutdown must occur every 24hours to
enable the unit to check its own efficiency (systems for
non permanent operation)
•
Connect and disconnect the unit only after switching off
the power supply
•
Avoid exposing the unit to dripping water
•
Ventilation and the lowest temperature ensures the
longest life of the control
Electrical Installation
•
Live and Neutral should be connected correctly; a mistake
could cause a dangerous situation.
•
Before starting the system check cables carefully for
incorrect installation
•
The earth terminal of the control, the metal frame of the
burner and the earth on the mains supply must be well
connected

Operation
At every start, the control unit proceeds to a self-checking
of its own components. During the pre-purge or waiting
time (TW) the internal circuit makes a test of the flame signal
amplifier. Extraneous light or fault in the amplifier will result
in the simulation of a flame which will prevent the control
from starting.
At the end of the waiting or pre-purge time, the gas valve is
energised and the ignition device is operated. In this way, the
safety time (TS) begins.
If a flame is detected during the safety time, the ignition
device is inhibited and the gas valve remains energised.
If the control does not detect any flame signal during the
safety time, at the end of safety time (TS), the unit proceeds
to lockout and the gas valve and ignition device are switched
off.
If the established flame signal is lost, (during the safety time
or during operation thereafter) this will cause the ignition
device to be reactivated within 1 second.
If the burner does not light within 25 seconds of ignition
reactivation, the heater will enter failure lockout mode and
must be reset.
