Led Indications
The working operation and status of the humidifier is indicated using 4 LEDs on the front
panel.
7.1
Normal Operations
In the case of normal operation the green led (1) is lit with an intensity proportional to the
mist production. If the external or internal controller does not require mist production, the
green led (1) blinks.
In the case of absence of water (insufficient pressure or solenoid input valve failure) the
yellow (4) led light to indicate that there is no mist production.
Red led (2) and (3) must be OFF.
7.2
Tank Cleaning
The microprocessor based control system, performs automatic tank cleaning at start-up and
every 6 hours of operation. This cleaning phase allows limestone deposit to be eliminated
from the tank.
During this cleaning phase green led (1) blinks to indicate that the humidifier is working,
but not producing mist.
Tank cleaning is performed in two phases signalled by a different state of red led (2):
Water input in the tank and starting of the siphon system (red led (2) is ON)
Cleaning and draining of the tank (red led (2) is blinking)
The yellow led (4) indicates the level of water in the tank.
Connect the external Controller to the
terminals REG and 0V as in the schematic
