7. Automatic Control
When auto mode is ON, output is regulated according to ambient temperature T.
For this purpose, 3 parameters are necessary:
Fan Speed, Temp Start and Temp Stop.
When T is equal to Temp Start, output is ON at Fan Speed.
When T is equal to Temp Stop, output is OFF.
If Temp Start < Temp Stop, output is in heating mode.
If Temp Start > Temp Stop, output is in cooling mode.
Temp Start = 20°C and Temp Stop = 25°C
Whenever T is inferior or equal to 20°C, output is activated, for example an electric heater, until T rises above 25°C (or equal).
Temp Start = 25°C et Temp Stop = 20°C
Whenever T is superior or equal to 25°C, output is activated, for example an extractor fan, until T drops below 20°C (or equal).
Important: if you use a relaybox, Fan Speed must be set to 100%.
