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
