SAFETY AND DETECTION DEVICES
Feed Screw safety thermostat
placed near the pellet hopper. It disconnects the electrical supply to the gear motor if the temperature detected is too high.
Overpressure valve
upon reaching the pressure stipulated on the plate, the system is triggered to discharge the water and consequently the water must be
topped up.
WARNING!!!! remember to carry out the connection with the sewage system.
Manometer
located on the rear left side (Esprit-Magic-Prestige) and beneath the front sheet metal top (Basic), it allows you to read the water pres-
sure in the thermal stove. With the thermal stove running, the recommended pressure is 1bar (see page. 38).
IF THE THERMAL STOVE BLOCKS, THE REASON WILL APPEAR ON THE DISPLAY AND THIS WILL BE SAVED.
Resistance
triggers pellet combustion. It remains on until the smoke temperature increases by 15 °C from that prior to ignition.
Smoke extractor
"pushes" the smoke into the flue and draws out combustion air via a vacuum.
Gear motors
activates the feed screw, which allows the pellets to be transferred from the hopper to the combustion chamber.
Pump (circulator)
"pushes" water toward the heating system.
Closed expansion tank
"absorbs" the variations in the volume of water contained inside the thermo-stove due to the heating effect.
A heating technician must evaluate the need to add a second tank to the existing one, depending on total amount of water in the system.
Venting valve:
positioned in the upper part, it allows for the "bleeding" of any air present during the loading of water inside the stove.
Drain tap
placed inside the lower part of the thermal stove. This is to be opened if the water inside the thermal stove must be emptied.
THE ELECTRONIC CIRCULATOR
The BASIC is equipped with a circulator with a new generation electronic
motor.
Electronic control of operation:
Pressure differential
a) Control mode Δp – c
In this mode, the electronic controller keeps the differential pressu-
re generated by the pump at a constant set value of H s.
Volume flow
b) Control mode Δp – v
In this mode, the electronic controller varies the pressure differential between
the set value Hs and 1/2 Hs. The pressure differential varies with the volume
flow.
Pressure differential
Volume flow
c) Venting procedure
This procedure allows the expulsion of air present in the hydraulic circuit.
After manual selection of the "AIR" mode, the pump will automatically alter-
nate between maximum and minimum speed for 10 minutes. At the end of the
procedure, the circulator will go to the pre-set speed. You can then select the
desired mode of operation
