Technical Overview

System Description
ELECTRONIC CONTROL
. The control consists of a main power located on display board.
COOKING MODE & TEMPERATURE SELECTORS
. All ovens have one selector for the cooking
modes and one for the set temperature.
TEMPERATURE SENSOR
. There is one Pt1000 sensor, fixed on the rear wall outside the cavity.
HEATING ELEMENTS.
Four heaters are available in multifunction ovens while the ring element is
missing in the thermal ones. They are combined together in different ways, depending on the
selected mode, but the maximum power never overtakes 3000W.
o
UPPER ELEMENT 2000+1000W at 240V.
o
LOWER ELEMENT 1200+400W at 240V.
o
RING ELEMENT 2500W at 240V.
CONVECTION FAN.
This fan is available in multifunction cavities; it works always at the same
speed in all convection modes, self-clean and dehydrate.
COOLING FAN SYSTEM.
A cooling fan keeps the internal parts temperature within acceptable
values, and removes smoke from the cavity through the catalyser. There is a 70°C by-pass
thermostat that shorts this resistor when the temperature overtakes the threshold, switching the
cooling fan into its full speed. This normally occurs during self-clean only.
OVEN LIGHTS.
Incandescent 230V lamps.
They turn on when a cooking mode starts.
DOOR LATCH SYSTEM.
A motor actuates the latch mechanism to lock or unlock the door. The
motor always rotates in the same direction, and it’s the mechanism that determines the locking or
unlocking phases. They take about the same time to complete the half cycle. A changeover micro
switch placed right on the motor shaft and actuated by a 180° cam provides the electronics with the
latch position information.
