Programming indicator
It is displayed only in the automatic programming mode, indicating the
possibility to edit the time slot of both the CH circuit and of the boiler.
First alphanumeric indicator
Alphanumeric values indicating the current time during standard operation, or
the specific time during automatic programming of both the CH circuit and of
the boiler.
It indicates the fan speed (in rpm) during the “flue cleaning" function.
Flue cleaning function indicator
It flashes when the flue cleaning function is started (by pressing the reset key
for three seconds) and then remains steady on once the function is active.
During such function, the fan rpm is displayed by the first alphanumeric
indicator, while the flow temperature is displayed by the second indicator.
Temperature indicator
Respectively: sun=day or comfort, moon=night or reduced temperature.
When the automatic programming operation is active, the single indicators
are lit in a steady way to indicate the current temperature.
They will flash during the setting of the relevant temperatures.
Daytime temperature indicator
Daytime temperature time slot (sun) during the programmed operation.
Night-time temperature indicator
Night-time temperature time slot (moon) during the programmed operation.
COMFORT function indicator
Icon on, steady = function enabled;
Icon off = function disabled.
Boiler status indicator
Icons indicate the operating modes enabled:
- instantaneous
DHW;
- heating.
DHW indicator
It turns on while the boiler is fulfilling a DHW request.
It flashes when setting the DHW temperature with the key 5 (see previous
paragraph).
Central heating indicator
It turns on while the boiler is fulfilling a CH request.
It flashes when setting the CH water temperature with the key 9 (see previous
paragraph).
Fictitious ambient temperature indicator
In case an external probe is installed, this indicator flashes when the fictitious
ambient temperature is set with the key 9 (see previous paragraph).
Second alphanumeric indicator
This shows the following:
- flow water temperature during “heating” function;
- central heating water temperature setting;
- domestic hot water temperature during the “DHW” function;
- domestic hot water temperature setting;
- parameter value display
- boiler
diagnosis.
Centigrade degree indicator
When displayed simultaneously with the second alphanumeric indicator, it
shows the value expressed in centigrade degrees.
