When the controller is ON again, the compressor times are observed and all of the functions are reactivated, except for the de-
frost on start-up and compressor and evaporator fan delay at power on (par. c0).
Notice:
• the OFF command from digital input has priority over those from the keypad or supervisor;
• if the controller remains OFF for a longer time than the value set for parameter dI, a defrost is performed when the controller
is switched on again.

Curtain switch (par. DIG)
Digital input used to manage a curtain and switch from day to night (ECO).
During night status (ECO mode):
• the night-time set point Stn is used for control, calculated based on the set point St plus the off set defi ned by parameter r4
(Stn = St + r4) and r4d is used as the control diff erential. The control probe can also be modifi ed according to the setting of
parameter r6a (0 = virtual probe, 1 = probe), see the paragraph “Control”;
• the AUX or light output is deactivated according to the setting of parameter H8.
During day status:
• normal operation resumes: set point = St, virtual probe used as control probe;
• AUX or light output activated according to the setting of parameter H8.

Start/stop continuous cycle (par. DIH)
When the contact is closed, the continuous cycle is activated, based on parameters cc and ccE (see "Functions").
When the contact opens again, the continuous cycle is deactivated.

Generic alarm from digital input (par. DIS)
Activation of the alarm depends on parameter GFA_E. Activation of the alarm causes:
• message GHI shown on the display and service icon fl ashing;
• activation of the buzzer (see par. Hb);
• activation of the alarm relay (see par. DOb);

Low pressure switch (par. DIt)
If a low pressure switch is connected, the LP alarm is activated on opening. if pump down by pressure is enabled, the pressure
switch is used to switch off the compressor and the autostart procedure.
