Termostato - external chronothermostat
To use an external thermostat, contact an authorised technician
and for installation proceed as follows:
•
turn off the power by the main switch on the back and unplug
the power cable;
•
remove the side panelling to access the electronic controller;
•
referring to the wiring diagram, connect the two thermostat
wires to the respective board TERM terminals;
•
refit everything and check correct operation.
All the menu functions do not change for each of the settings and
signalling of the connection occurs with lighting up of the segment
LED on the status bar of the display.
If met, the thermostat shuts down the boiler, displaying the
STANDBY function on the panel (if on).
If an external thermostat-chronothermostat is used, it is advisable to deactivate the STANDBY mode and
deactivate the control unit CHRONO programming.
Activation of the external thermostat-chronothermostat is signalled by lighting up of the status bar segment LED on the display.
If met, the thermostat shuts down the boiler, displaying the STANDBY function on the panel (if on).
Idle period (end of season)
If the boiler is not used for long periods, and/or at the end of each season, it is advisable to proceed as follows:
•
remove all the pellets from the hopper;
•
disconnect the power supply;
•
clean thoroughly and, if necessary, have any damaged parts replaced by qualified personnel;
•
protect the boiler from dust with suitable covering;
•
store in a dry and safe place protected from atmospheric agents.
Boiler maintenance
Cleaning operations for all parts must be carried out with the boiler unplugged and cold;
Dispose of cleaning waste in accordance with the current local regulations;
The boiler must not be operated without its cladding;
Boiler cleaning is very important to prevent: poor combustion, deposits of ash and unburnt products in the brazier, reduced thermal
efficiency.
The boiler must only operate with the ash and fire door always closed.
The door seals must be checked periodically to prevent air from entering and ensure combustion chamber low pressure.
Routine cleaning is normally carried out by the customer following the instructions in the manual, whereas extraordinary maintenance,
at least once a year, must be performed by the authorised Service Centre.
Given below are the control and/or maintenance operations for correct boiler use and operation.
