Features:
A number of parameters are displayed alphanumerically to set
up the instrument for each specific function.
Single Operation Quick Freeze Mode(Press key for 2
sec), set system in quick freeze mode which is time based for
that period new set point will be lower than running set point
and system will try to achieve that set point, after time period
over set point will be normal set point.
This controller controls the defrost in the system based on
either an electrical heater where the compressor is stopped,
or at cycle inversion using warm gas where the compressor
keeps on working.
There are safety features which include shutting down the
system incase of a fault from a pressure control or similar
device.
A series of “safety controls” (delay at start-up, minimum disable
time, minimum time between activation) protects the
compressors from close starts. In case of probe error or
temperature alarm, the instrument signals the event through
acoustic signal and by closing the relay contact. By pressing
the mute key, the buzzer is silenced.
Computer Connectivity over RS485 and Remote monitoring
(Optional).
