The TRONICAM21 electronic control unit can be built into a three DIN module cabinet.
It gives complete control of the boiler-flue (heat flue) using a temperature selection switch to start the fan, with a led signal when it is running.
The exact temperature reading of the air is shown on the large display.
It has AUTOMATIC/MANUAL functions, signalled by their respective LEDs, to control the 8 level electronic speed regulator.
If it overheats (app 90°C) a sound and visual alarm triggers. The unit is fitted with a probe-housing pocket.
