Menu 05 – 3-Way Valve Threshold
5.
Allows setting temperature threshold for switch-over of 3-Way motorised valve installed in DHW system. Change-over happens after 30" from reaching
set temperature and with hysteresis of 2°C.
Example:
3-Way Valve Threshold = 55°C
The valve opens after 30" from reaching 55°C.
Valve closes if 52°C is reached.
Menu 06 – Acoustic alarm
6.
It allows enabling or disabling acoustic signal in case of alarm. Acoustic signal is only present on boiler board and not on external remote control.
Menu 07 – Initial load
7.
It allows pre-loading pellet for 90" with boiler off and cold. Start using key 1 and stop using key 4. It can be useful if the boiler is ignited once the tank has
been fully emptied or it is the first time it is filled.
Menu 08 – Stove state
8.
It allows displaying the instantaneous boiler's state showing the state of the various devices connected to it. Different pages displayed in succession are
available. As the reported data is reserved to Technical Assistance Centre we recommend not accessing this menu.
Menu 09 – Technical calibrations
9.
It allows to access all that reserved to Technical Assistance Centre. Access is protected by access key. Unauthorised access can cause serious damage to
the equipment, to persons and to the environment.
COMMISSIONING
Filling the system for the first time
After having connected the boiler, fill the system as follows:
Check pipe sealing of both the expansion vessel and the circulation pump;
Open "air vent valve" of boiler using the relevant key
Open the "load cock" to fill the system. Act very slowly to allow the air to escape the boiler through the "air vent valve"; the best working pressure
is 1.2 bar;
If necessary, very slowly loosen the pump bleeding plug, making the fluid flow for a few seconds;
Bleed all radiators and any other deaeration systems in order to ensure that there are no air bubbles.
When installation has been completed, for the first days of functioning it is recommended to check the tightness of all hydraulic joints.
The boiler system can be emptied from the "system drain cock" positioned near to the hydraulic connections behind the boiler
In intensely cold periods it is good practice that the heating system remains running. In the case of prolonged absence, anti-freeze must be added
to the heating water or the system must be completely emptied.
In a system subject to being emptied frequently it is indispensable that filling is performed with water that has been appropriately treated to eliminate
hardness that can lead to lime scale deposits.
Pellet loading and connection to the electric network
Perform the following operations:
Connect the boiler to the electric plant using the cable supplied;
Place the switch positioned on the rear of the boiler at "( "׀on);
Fill pellet tank; for commissioning we recommend using that reported in MENU 07 – INITIAL LOAD to avoid time required for filling the entire screw
feed channel (to be performed every time the boiler remains without pellets);
Switch the boiler on using the relevant ignition key on the Control Panel. See the instructions below.
It is recommended to use top quality pellets so as not to compromise the functionality of the boiler itself. Damaged caused by out-of-date pellets
are not covered by the warranty.
Boiler ignition cycle
Pressing button 4 (ON/OFF) for a few seconds allows to start the boiler ignition cycle. The display shows the wording "START", the flue gas intake device
and ignition resistance switch-on after a few moments. The boiler goes to useful pre-load phase "PELLET P-LOAD" to quickly fill the brazier with pellets
after 40 seconds. The boiler goes to "FLAME STAND-BY" after pre-load phase. Display shows the wording "FIRE PRESENT" with flame on. This phase is
used to allow the fire to evenly expand on the entire brazier. The boiler places itself in work mode at pre-set power after these phases.
In case of no pellet ignition, the boiler goes into "NO IGNIT-" alarm.
The alarm may occur also if the brazier is dirty; in this case, clean the brazier and re-start the boiler.
Summary:
The ignition cycle can last max 25 minutes and is divided into four phases:
1 - START
2 - P-LOAD PELLET
3 - FLAME STAND-BY
4 - FIRE PRESENT
The boiler goes to work phase at power set in ignition using buttons 1 and 2 after ignition cycle.
