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/dew point temperature limit set point (parameter SL) (*);
• limit proportional band (parameter bL) (*)
To return to the main display press ESC. Parameter C0 (see "Configuration
parameters") 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 the 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 (RS485 Carel/Modbus) the display shows "S - -"
alternating with the main screen.
If multiple disabling modes are active concurrently, these alternate
cyclically on the main screen. If the display shows "---", it means there
is a communication error between display and humidifier: check the
connection cable. If the problem persists, contact service.
(*) To modify the parameter displayed, press:
• ENTER (display:
);
• UP or DOWN to set the value
• ENTER to confirm the new value.
Press ESC to return to the main screen. The parameters can also
be accessed from the list of parameters (see chap. "Configuration
parameters").

2) during operation:
• on the display: from the main screen press ESC and UP together, the
following are shown in sequence: humidifier size and software release;
• via network on integer variable 81. Format "## = #.#" (e.g. 12 = release
1.2).
