4 General/Introduction
4.1. System Description
•ELECTRONIC CONTROL.
The control consists of a main power board and a display board. An additional power board is derived from the main one remov-
ing the power supply parts. It has all the functions of the main one to drive the lower cavity in a double oven. The main power
board provides the voltages to the other boards (GND, -5V and -24V for the relays to the lower power board only).
• The three boards share a I2C communication bus (Data and Clock).
•COOKING MODE & TEMPERATURE SELECTORS.
All ovens have one selector for the cooking modes and one for the set temperature, per every cavity. The cooking mode selector
has 4 positions for thermal cavities, 9 for multifunction ones.
•TEMPERATURE SENSOR.
There is one Pt1000 sensor per every oven (two in a double, of course), 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 3500W.
- UPPER ELEMENT 3500W at 240V.
- LOWER ELEMENT 3000W at 240V.
- RING ELEMENT 2500W at 240V.
- UPPER EXTERNAL ADDITIONAL ELEMENT 775W at 208V (meaning 1032W at 240V).
•CONVECTION FAN.
Convection fan. It works in all convection modes, in Fast Preheat and in Self-Clean. It makes the heat distribution uniform, inside
the cavity. According to the oven model, each cavity can be provided with 0, 1 or 2 fans, reversible or not.
•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 when the temperature overtakes the threshold, switching the cooling fan into
its full speed. This normally occurs during self-clean only.
•OVEN LIGHTS.
Halogen 120V lamps. They turn on when a cooking mode starts or when the door is open. It’s also possible to switch the lights on
manually by pressing the light button.
•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. The door
micro switch is checked every time the latch starts to verify that the door is actually closed. If the door is open, the latch icon
flashes until the door is closed. A changeover micro switch placed right on the motor shaft and actuated by a 180°cam provides
the electronics with the latch position information

4.2. Oven Model Set Up and Configuration
The control must be able to drive multifunction cavities, with one or two convection fans, and thermal cavities. Different oven mod-
els are possible as described in the following table.
4.2.1. Set Up
IMPORTANT: The MANUAL TEST procedure can be activated only within 5 minutes after power on.
The MANUAL TEST must be completed until the writing TEST END appears otherwise the oven model configuration
will be lost.
The manual test procedure must be completed when the main power board is replaced and confirmed as per the instructions in this
section. If the control has never been configured before, the display shows F11Err at power up. Once a configuration has been
accepted, the failure disappears.
At every POWER-UP, the control runs a latch auto-test cycle. The lock icon flashes while the latch is moving.

5.2. Oven Modes
The table below describes the cooking mode basic cycles. Each cycle is defined to guarantee the best heat distribution and perfor-
mances, depending on the mode. The table shows which heaters must be energized and how long, whether the fan has to work or
not, the temperature range and the standard preset value. The algorithm itself determines the optimum off time between two con-
secutive cycles.
An additional heating element is provided and used during self-clean when the main power supply is 208V. It’s also used when Fast
Preheat is requested.
5.3. General Oven Information
Before using your oven for the first time remove all packing and foreign materials from the oven. Any material of this sort
left in the oven may melt and/or burn when the oven is used.
5.3.1. Flashing Symbols or Numbers
Signals an incomplete setting and calls for another input.
5.3.2. Beeps
Signals that more information must be entered or confirms the
receipt of an entry. Beeps also signal the end of a function or an
oven fault.
5.3.3. Preheat and Fast Preheat
Whenever a cooking mode is set and the oven is heating, the
[PREHEAT] writing appears in the temperature display: the ver-
tical bar indicates, in four steps, when the oven reaches the
25%, 50%, 75%, 100% of the set-point temperature. As soon
as the 100% is reached, the control sounds an [end of preheat]
tone and the [PREHEAT] writing disappears. When it’s neces-
sary to heat up the oven rapidly, a Fast Preheat mode is avail-
able: it uses the heating elements and the convection fan in a
special way, in order to reduce the heating time as long as pos-
sible.
After having set one of the cooking functions for which the fast
preheat is available, touch the [FAST PREHEAT] key, the
[FAST] writing is shown in addition to the [PREHEAT]one.
As soon as the set-point temperature is reached, the control
sounds an [end of preheat] tone and both [FAST] and [PRE-
HEAT] writings disappear. The oven switches automatically to
the desired cooking mode that was previously set: put the food
inside now.

5.11. Replacing an Oven Light
• Each oven is equipped with halogen lights located in the lat-
eral walls of the oven.
• The lights are switched on when the door is opened or when
the oven is in a cooking cycle.
• The oven lights are not illuminated during SELF- CLEAN.
• Each light assembly consists of a removable lens, a light
bulb as well as a light socket housing that is fixed in place.
See figure on this page.
• Light bulb replacement is considered to be a routine mainte-
nance item.
To replace a light bulb:
1. Read WARNING on this page.
2. Turn off power at the main power supply (fuse or breaker box).
3. In ovens with lateral racks, remove them by unscrewing the four screws.
4. Remove the lens to prise between screw and glass using a screw driver.
5. Remove the light bulb from its socket by pulling it.
6. Replace the bulb with a new one. Avoid touching the bulb with fingers, as oils from hands can damage the bulb when it
becomes hot.
7. The bulb is halogen: use one with the same type checking Voltage and Wattage.
8. Replace the lens back on.
9. Replace the racks if it is provided with the oven model.
Turn power back on at the main power supply (fuse or breaker box).
WARNING!
• Make sure the oven and lights are cool and power to the
oven has been turned off before replacing the light bulb(s).
Failure to do so could result in electrical shock or burns.
• The lenses must be in place when using the oven.
• The lenses serve to protect the light bulb from breaking.
• The lenses are made of glass. Handle carefully to avoid
breakage. Broken glass could cause an injury.

5.13. Description of Electronic Control
A power module, described in the block diagram below, is able to manage one cavity. The main power board is also providing the
lower one and the display board with the power supply.
• An external safety thermostat, named STH, is placed in the appliance: it must always be connected in series with the heaters.
• ANTC temperature sensor is on the main power board: if an over temperature anomaly is detected during ordinary cooking, a
fault must occur and the display must show an error code.
• These two devices must prevent all the oven parts to overtake the maximum allowed temperature (for the electronics the 105°C
threshold), also in case of a cooling fan fault.
• Optionally, one external board can be provided to control the meat probe in the upper cavity.

HL-BD82S
17
5.14. Fault Codes
If the fault involves safety requirements or the correct oven functionality, any activity must be stopped until the fault is removed.
Every alarm condition can be reset manually by turning the cooking mode knob in the OFF position and the temperature knob in the
preset position. Of course, the cause of the failure must be first removed.
Whenever the fault doesn’t affect the whole oven functionality, allow the user to work:
• If the latch doesn’t work, ordinary cooking activities may run if the door is fully unlocked.
• In case of a F19 keyboard failure, allow to work manually in the main cavity only.
Every fault must have a time-out to be declared, to prevent false alarms. When a fault occurs, if the control can detect the failure, an
error number must be displayed, as shown in the table below.
Faults N°
Single oven RTD temperature sensor failure F01 Err
Single oven motorized latch or switches failure F03 Err
Single oven runaway temperature condition 650°FF05 Err
Single oven runaway temperature condition 950°FF07 Err

5.15. Oven Safety Features
5.15.1. Child - safe locking system
All of our ovens are built-in child-safe locking systems. The
future is automatically enabled any time the appliance is con-
nected to the power, any time the switch is turned on and any
time the oven is programmed to run a self-cleaning of the cav-
ity.
The same future it can be is used on the manual mode in the
household where a minor is present to prevent children from
getting in touch with hot parts. The function of this future is
explained in details on the chapter 5.3.5.User lock.
5.15.2. Over heating sensor
All of our ovens are built with a over heating sensor system:
• we have two bi-metal mechanical thermostats for each cav-
ity.
• an electronic sensor [NTC] or [negative temperature coeffi-
cients] mounted on the main power board (see chapter
5.13.Description of Electronic Control for more informa-
tion). The role of the [NTC] is to protect the electronic boards
of an eventually over-heating. (the [NTC] varies with the val-
ues of voltage, only DC, values tabulated at 5.13.Description
of Electronic Control)
An electronic [PTC] or [positive temperature coefficients] probe
mounted on the inside of the cavity who is responsible of the
inside cavity reading of the temperature. (the [PTC] varies with
the resistance — tabulated at chapter...)
5.15.3. Thermostat
All of our ovens are built with two bi-metal mechanical thermo-
stats for each cavity. The thermostats are mounted in contact
with the metal sheet on top of each cavity as shown in the
above pictures.
5.15.4. Double Speed Thermostat
The double speed thermostat is acting in conjunction with the
by-pass resistor and is connected in parallel with it.
In the regular cooking mode when the read temperature at the
surface of the metal sheet in under 158°F (70°C) the power is
flowing trough the resistor and it feeding the cooling fan with a
voltage AC 93V .
If the temperature of 158°F (70°C) is depassed, the thermostat
is closing the circuit and the resistor is by-passed and now we
can read at the poles of the cooling fan motor the full voltage of
installed AC 120V and the RPM of the cooling fan will almost
double.
The reset is automatic when the temperature at the surface of
the metal sheet decreases under the 158°F and the cooling fan
is reducing the RPM at the manufacturer factory set-up.
RPM — rotation per minute
5.15.5. Safety Thermostat
The function of the safety thermostat is to protect the of the
oven from over heating in the event of a malfunction of the cool-
ing fan.
Description: In the regular cooking mode when the read tem-
perature at the surface of the metal sheet in under 260°F
(127°C) the power is energizing the electronics and the heating
elements as well.
In the event that the temperature is rising over the 260°F (127
°C) limit, the thermostat will switch mechanically from off posi-
tion to on position and all of the heating elements will be cut off
from the power.
All of the electronics will be cut off.
The reset is manual when the cooling fan was replaced or the
oven problem was solved and the temperature is in the right
functioning parameters the red button on the top of case of
thermostat must be pressed to reset it (see picture on the pre-
vious page).
