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

When the selected programme has been chosen, a confirmation will be given on the onboard LED
display as follows:
•
Off Time of Day

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 50
0
C - max 250
0
C).
•
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 100
0
C.
Note: Full user set up details for the normal baking and grilling functions can be found in the User
