Door management
Standard operating mode (CE=0)
Door management allows for the installation's behaviour to be controlled, should the cold room door open through
parameters C22 and C23.
Parameter C22 defines whether cold production should be stopped if the door opens. If C22=1, when the door
opens, the fans stop and, 15 seconds later, the solenoid closes (COOL relay).
Parameter C23 defines the maximum time, in minutes, that the installation can remain without producing cold whilst
the door is open. If C23=0, cold is not produced with the door open.
SELFDRIVE operating mode (CE=1)
If the SELFDRIVE mode is active, in the case of opening the door, the fans stop, or do not stop, depending on param-
eter C22. If the door does not close, when the time set in parameter C24 has passed, cold production stops and does
not activate again until the time set in C23 has passed.
If, when the door is opened, cold is not being produced, only parameter C23 is taken into account.
Management of door frame resistor
If the set point is equal to or below -4°C and the relay AUX 1, 2 or 3 has been configured as “door frame resistor”
(o00, o10 o20=5), the resistor is activated (relay ON) when the temperature of the cold room store drops below -3°C,
and is deactivated (relay OFF) when 0°C is reached.
