The LCD terminal is an option and can
only be used if the auxiliary card is
fitted (UUKAX00000 optional, already
built-in on models UU01**A**1).
The terminal displays humidifier
status and can be used to customise
operation by setting the parameters.

8.2 Meaning of the symbols
Power supply (Green LED)
Humidifier operating (yellow LED)
Steady: humidity production in progress
Flashing: transitory status, atomisation temporarily paused
Alarm (red LED) - On activation of an alarm: LED flashing and
buzzer active - When an alarm is active, pressing ESC mutes the
buzzer and the LED comes on steady, pressing ESC again resets the
alarms (see Chap. "Alarms")
Time in seconds
Hour counter
Humidity production as a percentage of rated capacity
Parameter setup
Maintenance request (active alarm)
On steady: humidifier fan operating.
Flashing: fan on during deactivation phase
3 digits, after 999 the display shows to indicated the 1000s (the
three digits are displayed with a dot at the top between the first
and second digit).
Humidity production in progress
Tank filling
Water in the tank
Water draining from the tank (also shown when the unit is in
standby as the drain valve is normally open)

8.4 Main
display
The humidifier display normally shows control signal status. For ON/OFF or
proportional input signal (A0=0, A0=1, A0=3 and Th probe disconnected):
•
display input signal;
•
tank hour counter (h).
•
maximum water vapour production control (parameter P0) (*);
•
control hysteresis (parameter P1, only for proportional control A0=1) (*);
•
humidifier status (Enb = enabled): pressing ENTER disables the
humidifier and dIS is shown on the main screen.
For humidity probe input signal (A0=2, A0=3 and and Th probe
connected) or dew point temperature control (A0=4):
•
display humidity probe reading;
•
tank hour counter (h).
•
maximum water vapour production control (parameter P0) (*);
•
proportional band (parameter bP)(*);
•
humidity/dew point temperature set point (parameter SP)(*);
•
humidifier status (Enb = enabled): pressing ENTER disables the
humidifier and dIS is shown on the main screen.
If enabling probe TH as a humidity limit probe (bH=1) or as a dew point
temperature limit probe (bH=2) in control modes A0=0, A0=1, A0=2, the
following parameters will be added to the main screen:
•
humidity setpoint limit / dew point temperature (parameter SL)(*);
•
limit proportional band (parameter bL) (*)
Parameter C0 (see Chap. "Configuration parametes") can be used to
change the value shown on the main display (default: display input
signal).
Disabling options:
•
from remote (ON-OFF contact open), the display shows “C - -”
alternating with the main screen;
•
on the display, by pressing ENTER on Enb, the display will then show
dIS (to enable it again, press ENTER); for a main/secondary network,
this only disables the individual humidifier in question;
•
from display (pressing Esc for 5 s), the display shows “t - -” alternating
with the main screen, for a main/secondary network, this will disable
all of the humidifiers in the network; to switch back ON, press ESC for 5
s until t - - is no longer shown;
•
from supervisor (RS 485 Carel/Modbus) the display shows “S - -”
alternating with the main screen;
