Functions of the Electronic Circuit
4.1
The electronic board located inside the unit controls all of the humidi
fi
er functions. The front LED panel
is equipped with pilot lights indicating the status of the humidi
fi
er. Please see Fig.4a.
Please refer to Article 4.2 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 humidi
fi
er enters standby mode. The
fl
ashing of the pilot lights indicates which error has
occured. 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.
4.2
The Acu-Steam PRO 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 more serious warning codes from the humidi
fi
er control
panel when connected with ON/OFF control. If ever the red light is lit or
fl
ashing on the humidistat, you know
immediately that the humidi
fi
er needs attention.
