Fig. 8.a
The LCD terminal is an option and can
only be used if the auxiliary card is tted
(UUKAX00000 optional, already built-in
on models UU01**A**1). The terminal
displays humidier status and can be used
to customise operation by setting the
parameters.

8.2 Meaning of the symbols
Power supply (Green LED)
Humidier operating (yellow LED)
Steady: humidity production in progress
Flashing: transitory status, atomisation temporarily paused
Alarm (red LED) - On activation of an alarm: LED ashing 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: fan humidier active

three digits are displayed with a dot at the top between the rst
and second digit).

8.4 Main display
The humidier 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) (*);
• humidier status (Enb = enabled): pressing ENTER disables the
humidier 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)(*);
• humidier status (Enb = enabled): pressing ENTER disables the
humidier 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. "Conguration 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 humidier 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 humidiers 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;
• from TAM (dip-switch 7 in ON position and current not detected by
TAM), the display shows "F - -" alternatively to the main screen.
