Functions of the Electronic Circuit
5.1
The electronic board located inside the unit controls all the humidifi er functions. The front panel is
equipped with pilot lights indicating the status of the humidifi er. Please see Fig.5a.
Please refer to Article 5.2 for the description of the functions.
The red pilot light, which is a warning light, can either glow all the time or fl ash when activated.
In case of error, the humidifi er enters stand-by mode. The fl ashing of the pilot lights indicates which error
happened. The error recognition sequence is as follows :
The green pilot light near the power button blinks once;
The red light fl ashes a certain number of times, this is the error code;
A pause with no light at all;
Another blink of the green light, once;
Another series of fl ashing of the red light;
And so on until the condition is reset or service is performed.
Shutting the power OFF at the breaker in the main panel or depressing the power button until the
green light is fully on will reset the error code.
5.2
The ACU-STEAM humidistat also has two pilot lights to indicate the current status.
The green light is lit when the humidistat is demanding for humidity, thus activating the boiling cycle. The red
light indicates a warning and reproduces the same warning code as the red light on the humidifi er control
panel. If ever the red light is lit or fl ashing on the humidistat, you know immediately that the humidifi er needs
attention.
