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 reached the set value (Tset + ΔT) for
a given time.
The next automatic relighting will be possible only when the temperature falls below the SET temperature by a few degrees and
precisely (Tset - ΔT) where ΔT 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 time. It starts with
button P1 and stops with button P4.
Menu 03 – User setting
With this menu it is possible to carry out the following settings:
- Language
With this selection it is possible to select the dialogue language from those available entered in the menu, and namely: ITALIAN -
FRENCH - ENGLISH - GERMAN – SPANISH
- Buzzer
With this selection it is possible to activate/deactivate boiler acoustic signalling.
- Lighting
With this selection it is possible to change the brightness of the backlit display from a minimum of 0 to a maximum of 100.
- Heating Delta
With this selection, it is possible to set:
•
the range between the SET temperature and the actual boiler shutdown temperature;
•
the range between the SET temperature and the actual boiler relighting temperature.
This range can be set from a min. of 0.5°C to a max. of 20°C depending on the customer’s needs and/or the type of system.
- Boiler/Puffer Delta
With this selection, it is possible to set:
the range between the SET temperature and the actual boiler relighting temperature.
This range goes from a min. of 0.5°C to a max. of 20°C depending on the customer’s needs and/or the type of system.
- Pellet level
With the selection set to ON, the no pellets signal can be managed with:
- a message on the panel ‘NO PELLETS’;
- management of a supplementary pellet hopper (available on request).
With the selection OFF, the possible supplementary hopper is disabled and no message appears on the panel.
- DHW control
The selection ON allows to manage DHW from the storage tank or heat exchanger through the signal from the thermostat or flow
switch.
The selection EST allows domestic hot water to be controlled in the summer (with heating off), via the signal from thermostat or
probe. Selecting this item enables operation of just the DHW branch; standby is forced to ON and post-circulation follows that set in
the menu M-6-9.
The summer function can be displayed only if the menu M-6-8 is set to T-PUFFER or S-PUFFER.
Menu 04 – boiler status
With this selection it is possible to display the instantaneous boiler status giving the operating status of the various devices connected
to it; various pages placed in succession are available for monitoring.
Menu 05 – Technician settings
This selection is reserved for the Aico SpA service centre authorised technician.
Modification of the technical parameters of menu 05 must be done by authorised and competent personnel; any
changes made at random can cause serious damage for which Aico SpA declines any liability.
