Indication during operation
Heating
A heating demand (generated by the Room Thermostat or Remote Timer Control) is in-
dicated by flashing of the hot air above the radiator on the display.
The display (detail 11 - fig. 1) shows the actual heating delivery temperature and, during
heating standby time, the message "d2".
Domestic hot water (DHW)
A DHW demand (generated by drawing domestic hot water) is indicated by flashing of
the hot water under the tap on the display.
The display (detail 11 - fig. 1) shows the actual DHW outlet temperature and, during
DHW standby time, the message "d1".
Comfort
A Comfort demand (reinstatement of temperature inside the boiler) is indicated by flash-
ing of the water under the tap on the display. The display (detail 11 - fig. 1) shows the

2.3 Lighting and turning off

Connection to the power supply
• During the first 5 seconds the display shows the card software version.
• Open the gas cock ahead of the boiler.

B
The antifreeze system does not work when the power and/or gas to the unit are
turned off. To avoid damage caused by freezing during long idle periods in win-
ter, it is advisable to drain all water from the boiler, DHW circuit and system; or
drain just the DHW circuit and add a suitable antifreeze to the heating system,
complying with that prescribed in sec. 3.3.
