Special functions
Network frequency self-learning
The board can automatically optimise the functioning times in relation to the network frequency measured (50 or
60 Hz).
Temporary shutdown
With ignition request in progress or burner functioning, it is possible to temporarily force a stop by continuous
pressing of the key for longer than 5s (yellow fast flashing).A new start-up cycle is allowed only when the key is
released.It is possible to activate the function in question also with the external release button.The function in
question can only be activated by accessing the INSTALLER MENU.

Protection in case of low voltage power supply
The power supply voltage must be at least 180Vac in order to allow a starting cycle to be performed.If the network
voltage falls below 156Vac, the appliance stops and signals the anomaly.The starting cycle can only be carried
out again if the power supply voltage exceeds 180Vac.
Protection in case of high power supply voltage
The power supply voltage must be at below 275Vac in order to allow a starting cycle to be performed.If the net-
work voltage exceeds 280Vac, the appliance stops and signals the anomaly.The starting cycle can only be carried
out again if the power supply voltage falls below 275Vac.
Functioning in manual mode for burner calibration
(delegated to authorised staff).
I
t the appliance is not in the block state, it is possible to force the MANUAL functioning mode by acting on the
button on the board or on the remote release button.In fact, by pressing the button 3 times (on the board or remo-
te reset) access the green fast flashing display; another press causes the activation of the MANUAL functioning
mode.In this phase, the appliance initiates the start-up cycle or remains functioning independently from the status
of the heat request thermostat and the functioning regulator. Once the functioning position has been reached, it is
