6.15.1 Analogue input confi guration for humidity
probes
Either analogue input B4 or B5 needs to be confi gured a humidity probe
input.

Example:
Humidity probe with 0 to 10 V output -> connect the probe to input B4
and set
• /P4=2
• /A4=2
Humidity probe with 4 to 20 mA output -> connect the probe to input
B5 and set
• /P5=0
• /A5=1
6.15.2 Display humidity reading on UltraCella
On models with single row display, P/Ns WB000S*, the humidity can be
displayed instead of the cold room temperature, selecting:
• Humidity probe with 0 to 10 V output -> /t1=10 (B4)
• Humidity probe with 4 to 20 mA output -> /t1 = 11 (B5)
Par. Description Def Min Max U.M.

…
10 = B4
11 = B5

On models with double row display, P/Ns WB000D*, the humidity can
be displayed on the second row as the second process selecting:
• Humidity probe with 0 to 10 V output -> /t2=10 (B4)
• Humidity probe with 4 to 20 mA output -> /t2 = 11 (B5)
Par. Description Def Min Max U.M.

6.15.3 AUX1 / AUX2 auxiliary output confi guration
and basic humidity control logic
To activate the humidifi er connected to UltraCella, confi gure one of the
auxiliary outputs AUX1 or AUX2 for humidity control.

Basic humidity control logic: if the humidity measured is less than the
set point StH, the relay activates the externally connected humidifi er
(REVERSE action, standard ON/OFF with diff erential).

Note:
1. If the temperature inside the cold room is less than 2°C (virtual
control temperature Sv) -> humidifi er activation (AUX1/AUX2 relay)
is always disabled (with a fi xed hysteresis of 1°C).
2. Humidity control can be disabled during the defrost (parameter F4):
• F4=0 -> humidity control enabled based on humidity set point
StH;
• F4=1 -> humidity control not enabled: during defrost, the
external humidifi er will not be activated.
3. Humidifi er activation (AUX1/AUX2 relay) is always disabled in the
event of an alarm that immediately stops the compressor. Examples:
• CHT alarm;
• LP alarm (after 3 times);
• IA alarm (when A6=0).
