Connected to the mode selector (ST4), the electronic programmer (EL1000) verifies the
programme selection by comparing the resistance on the selector with that stored on the
programmer's microchip.
When the selected programme has been chosen, a confirmation will be given on the onboard LED
display as follows:
• Off
• Oven light
• Defrost frozen foods
• Convection cooking with ventilation
• Traditional convection cooking
• Ventilated cooking with double grill
• Grilling
• Ventilated grilling
• Self cleaning function
If the door is open when the mode selector is operated, "door" symbol will appear and an audible
warning will sound for 30 seconds with the "door" symbol flashing.
Normal Baking & Grilling Function
When a baking or grilling function is selected and the customer verifies the temperature, the
following will be triggered by the Electronic Programmer (EL1000):
• Set Temperature displayed on LCD (min 122
• Internal cavity temperature confirmed by ST1 probe.
• Thermostat relay 1 operated and the thermostat contacts closed.
• Door status confirmed by ST3 microswitch.
• Cooling fan triggered by Triac 1 (old version programmer) or relay 4 (new version
programmer).
• Oven fan relay 2 operated.
Power is now supplied via the safety thermal overload to the various switch terminal configurations
on the mode selector and on to the various elements.
The internal cavity temperature is now constantly monitored by the ST1 probe and will trigger the
making and breaking of the thermostat relay 1 to ensure correct temperature control. The oven
thermostat light will also illuminate to indicate power to the elements.
Triac 1 (old version programmer) or relay 4 (new version programmer) maintains cooling fan
operation until the selector switch is turned to the "Off" ,"Light" or "Defrost" position and the inside
oven cavity drops below 212
Note: Full user set up details for the normal baking and grilling functions can be found in the User
Operating Instructions.
