IDPlus

971 devices are controllers with 2 relay outputs, 2 temperature sensors (regulation

and evaporator), a multifunctional Digital/Temperature input and a digital input.

* When switched on, the device performs a Lamp Test; the display and LEDs will flash for several seconds to check that they

all function correctly.* To activate the LOC function: - enter the "Basic Commands" menu by pressing the key set press keys and within 2 seconds. If

the LOC function is Active and you try to enter the "Programming" menu, the text LOC appears. If this happens, the

parameters

are still displayed but cannot be edited. To disable the keypad lock, repeat the aforementioned procedure.

compressor- defrost heating elements- evaporator fans- AUX output- temperature alarm- Standby The second probe can be used to control the defrost cycle and the evaporator fans. The

Digital inputs (D.I.1 and D.I.2) can be used for:

Energy saving- Defrost activation

AUX management- door switch- Standby- external alarm- Deep Cooling- pressure switch

HACCP alarms
