Bimetallic thermal cut-out (heater)

The thermal cut-out should respond when localised overheating occurs, e.g. if the air flow or

electrical temperature control fails.

If a fault occurs, the thermal cut-out must be manually actuated by pressing the red reset

button.

Response temperature: 160–175 degrees Celsius

Door switch and safety functions

All relay activations are controlled via the door switch. When the door is open, relays cannot

be activated.

When the door is closed and the mains switch is on, the capacitor is charged via a processor

output. Its voltage is monitored by an analogue input.
