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 (details 24 and 25 - fig. 1).
The heating graduation marks (detail 26 - fig. 1) light up as the heating sensor tempera-
ture reaches the set value.
Domestic hot water (DHW)
A DHW demand (generated by drawing domestic hot water) is indicated by flashing of
the hot water under the tap (details 12 and 13 - fig. 1).
The DHW graduation marks (detail 11 - fig. 1) light up as the DHW sensor temperature
reaches the set value.
Hot water tank exclusion (economy)
Hot water tank temperature maintaining/heating can be excluded by the user. If exclud-
ed, domestic hot water will not be delivered.
When hot water tank heating is activated (default setting), the COMFORT symbol (detail
15 - fig. 1) is activated on the display, and when off, the ECO symbol (detail 15 - fig. 1)
is activated on the display.

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.
