Gas boiler contact (Optional)
The cooker features (optional) a contact that switches on the gas boiler if the cooker goes in alarm state.
• The output must be connected to the terminal on the cooker – G6 (on relay NC contact)
• The output behaves as follows: when the cooker goes in alarm state, it de-energizes the relay that turns on the NC contact to
which you can conveniently connect the ignition contact of the gas boiler. Contact that activates as soon as the cooker goes in
switch-on mode.
Home automation (Optional)
The cooker may feature the option to manage an electronic board input contact and a signal output STOVE STATE in order to
interface the product with an advanced home automation system. Below is the description of home automaton system operation so
as to interface it even with programmable home automation systems.
• The input should be connected to the terminal on the board – G5
• The output must be connected to the terminal on the board – G6 (on relay NO contact)
• To turn on or off the cooker, you must give a pulse of at least 1s to the G5 input (contact closure for at least 1s); between one
pulse and the other must be a pause of at least 1 s.
• The output behaves as follows: upon each ignition, it activates for 2s, upon each switch-off it activates for 4s, in alarm mode it
remains always active (there is always a pause of 1s between one activation and the next; example if switch-on occurs right
after a shutdown the output behaves as follows: ON for 2s / OFF for 1s / ON for 4s).
• If an alarm is triggered, the home automation cannot reset it (to reset the alarm please refer to ALARMS chapter.
