3.1. Overtemperature Control (if fitted)
The hydraulic thermostat overtemperature controller should typically be set at 15°C above the
main controller. If an overtemperature condition occurs, always investigate the possibility that
the main control system has failed.
An overtemperature condition always cuts off power to the heating elements. To reset the
condition, first either allow the oven to cool, or increase the overtemperature setting.
If the overtemperature trip operates then a click occurs and a warning light near the thermostat
lights up; the reset button on the thermostat pops out. The reset button is hidden behind the
control dial: to reset the oven it is necessary to turn the thermostat dial till the hole lines up with
the reset button and press it using a small diameter rod.
