10. CONTROL PANEL
Once the unit is powered on, it must
be activated by pressing the ON/
OFF key on the control panel with the
LCD display located near the drawn air
intake. The actual start-up of the fan
and compressor is subject to the control
chain of the upstream enabling consents
(humidistat call, water inlet and air inlet
temperatures).
The SET key allows the display of the oper-
ating parameters and their value, with the
UP / DOWN keys the list of these parame-
ters is scrolled.
LED 1 (green) turns on steady, which con-
firms that the unit is on (compressor and/
or fan running). The same LED flashes
when the compressor or fan turn on after
a set delay. The lighting of LED 2 or LED 3
indicates an alarm condition according to
the table on page 29
