Remote ON/OFF (par. DIF)
When the controller is OFF:
l
the user terminal shows the value measured by the set probe (parameter /t1) alternating with the
message OFF;
l
the auxiliary relays set as AUX and light remain active, while the other auxiliary outputs are
deactivated;
l
the buzzer and alarm relay are deactivated;
l
the following are not performed: control, defrosts, continuous cycle, temperature alarm signals;
l
the compressor protection times are observed;
l
switching ON from the keypad, supervisor or remote control is ignored.
When the controller is ON again, all the functions are reactivated, except for the defrost on start-up and
compressor and evaporator fan delay on power-up (par. c0).
Note:
l
the OFF command from digital input has priority over those from the keypad or supervisor;
l
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)
During night status:
l
the night-time set point Stn is used for control, calculated based on the set point St plus the offset
defined by parameter r4 (Stn = St + r4). The control probe can also be modified according to the
setting of parameter r6 (0 = virtual probe, 1 = air on probe), see the paragraph “Control”;
l
the AUX or light output is deactivated according to the setting of parameter H9.
During day status:
l
normal operation resumes: set point = St, virtual probe used as control probe;
l
AUX or light output activated according to the setting of parameter H9.

Start/stop continuous cycle (par. DIH)
When the contact is closed, the continuous cycle is activated, based on parameters cc and c6 (see
"Functions"). When the contact opens again, the continuous cycle is deactivated.

Digital input monitoring (par. DII)
The supervisor is able to detect the status of the digital input. The value is affected by reversing the logic
of the input using parameter rII.
