The main board collects the information given by the control panel, the door switch and the
thermocouple, and controls the fans and the motor unit of the air box. The main board is also
equipped with a PLC communication system that allows communicating information to optional
extension boards via the 24VDC power supply cable.
Fans
Two fans blow out air between the heating element and the case to improve heat recovery. This
increases heat diffusion and distribution in the room.
The right-hand fan is connected directly to the main board. The left-hand fan is connected by
means of a cable running through a metal groove underneath the appliance, between the left
side and the main board.
The main electronic board allows the user to automatically vary the fan speed and to check their
operating condition.
Engine unit
It consists of a stepper motor, a motor nut, two compression springs and an electromagnet. It
enables the air valve of the air box to move. This movement allows the air passages of different
channels to be modified, carrying the combustion air to various places in the combustion
chamber:
- Air under the grate;
- Primary air (front and rear distributors);
- Secondary air (post-combustion);
- Smoke extraction air (window cleaning).
A safety system, integrated to the Easy system, allows the complete closure of the primary air in
case of power failure. When the system is no longer powered, the fans no longer operate and
the appliance is no longer cooled efficiently. By shutting off the primary air inlets (grate and
distributors), this safety system reduces the power of the appliance to limit the risk of
overheating. In this case however, the user can continue to use the appliance (supplied
exclusively with secondary air) at reduced power.
