4.7 Light management
The light can be managed:
• from door switch (if A3=0) and/or light key;
• only from light key.
Below are indicated the involved parameters.
Par. Description Def Min Max U.M.

Note: if the control is OFF, the light output is controlled only by
the light key. If the control is set to ON, the light is controlled by a
door switch + light key or just light key according to the setting of the
parameter A4.
4.7.1 Door switch + light key
If A4=1 the light is on/off only using the light key. The open/closed status
of the door is ignored. If A4=0, when the cold room door is opened, the
light is always on. When the door is closed, the light can be turned on or
off using the light key. Once turned on, the light will automatically turn
off after the time set in parameter tLi.

4.8 Other confi guration parameters
The confi guration parameters must be set during the commissioning of
the controller and concern:
• date/time set;
• measurement stability of the analogue probes;
• display of the decimal point on control;
• serial address for monitoring network connection;
• ithe type of protocol on the BMS serial port for connection to the
supervisor network
• temperature measurement unit (°C / °F);
• disabling of keyboard, keys and buzzer;
• display view during defrost.
Date/ time set
See example 2 in chap.3.
Analogue probes measuring stability
It defi nes the fi lter coeffi cient used to stabilize the temperature
measurement. Low values assigned to this parameter allow a prompt
response of the sensor to temperature variations, but the reading
becomes more sensitive to disturbance. High values slow down the
response, but guarantee greater immunity to disturbance, that is, a more
stable and more precise reading.

Display view
On models with single row display, P/Ns WB000S*, it is possible to show a
single characteristic, selectable through /t1 parameter.
On models with two rows, P/Ns WB000D*, and on the UltraCella Service
terminal, it is possible to show two diff erent characteristics, the fi rst
selectable through /t1 parameter, and the second through /t2 parameter.
