Overtemperature warning

At heat sink temperatures of approx. 90 °C and above, the IA receiver
automatically reduces the heating power to 50 %.
If the ▲ or ▼ button is pressed while the heating power is reduced,
the IA receiver switches to 100 % heating power for
2 seconds, but then drops back to 50 %.
Once the heat sink temperature falls below 80 °C, the IR Radio
Dimmer can be operated normally again.
Overtemperature shutdown
At a heat sink temperature of approx. 100 °C and above, the radiant
heater is switched off by the IA receiver.
If the ▲ or ▼ button is pressed while the radiant heater is switched
off, the IA receiver switches to 100 % heating power for 2 seconds,
but then switches the radiant heater off again.
Once the cooling temperature drops below 90 °C, the IA receiver
switches to the overtemperature warning state.

Emergency shutdown

At a heat sink temperature of approx. 110 °C and above, the radiant
heater is switched off by the thermal switch in the IA receiver. This
