Overheat alarm
The controller has a temperature sensor for the internal heatsink.
The temperature value of the heatsink is in variable IN_NTC; the over_heat alarm trips when the temperature
exceeds 105°C.
This condition may be caused by obstructed air vents or by a blocked cooling fan.
With the over_heat alarm on, the control disables control output SSR.
There is another maximum temperature protection that disables the hardware for the SSR control.
