SEZIONE 5 - OPERATION OF THE UNIT AND SETTINGS
5.1 – Automatic Sequence
If a humidistat is used set this to 100% so the contacts are closed. Set the thermostat to a low
temperature set point so the contacts are closed.
Put the cooler into Automatic Mode. The cooler will start at speed 3 in cooling mode. After 10
minutes the cooler will move to speed 4 and after a further 10 minutes the cooler will move to
maximum speed 5.
Now set the thermostat to a high temperature set point so the contacts are open. The cooler will
now slow down by one speed every ten minutes. If a humidistat is used then check its operation by
reducing its set point to a low value so the contacts open. The water circulation should then stop.
Then reset the humidistat to 100%.
The cooler should then slow down progressively until it is on speed 1 vent mode. If dip switch 8 is
enabled the cooler will stop completely.
5.2 – Connections of Remote Items
The wall control box for the AD 14 has a serie wires for optional connection to remote
items. They are contained on a separate terminal block in the wall control box.
The wires are:
Yellow/black – Alarm
Red/black – Common
Green/black – Timer
Orange/black – Thermostat
White/black – Humidistat
The cooler is delivered with the Light Yellow/Alarm and Light Green/Timer contacts
bridged. The cooler will not operate without these contacts being made.
