4.6.2 Menu 02 - User adjustments

With this menu it is possible to do a number of settings as follows
- Set clock
Before operating with the boiler, it is necessary to set the current time and date so that there is a reference for
possible chrono programming. The electronic controller has a lithium battery, model CR2032 3 Volt, giving the
internal clock an autonomy of more than 4-5 years; with the boiler off, whenever the clock does not keep the time, or
a series of zeros is displayed at restart, the battery must be replaced by calling an authorised service centre.
- Standby mode
On activating this function, the boiler shuts down automatically after the water temperature has remained above the
SET value for a fixed time.
The next automatic relighting will be possible only when the water temperature falls below the set value entered in
the parameters table (default 2°C).
Manual commands from the control panel have priority over programming.
With the selection OFF the boiler does not activate the STANDBY mode and functions normally activating the
MODULATION function when the temperature exceeds the SET value.
- Initial load
Setting this function allows activation of gearmotor operation, with the boiler off or cold, for pellet preloading of 90
sec. It starts with button P1 and stops with button P4.
- Pellet type
With the function on, press the buttons P1 or P2 to increase or reduce pellet loading to optimise consumption and
combustion, depending on the type of pellets used.
- Initial load auger 2
Setting this function allows activation of gearmotor operation relevant to the supplementary hopper for a fixed
preload. It starts with button P1 and stops with button P4.
