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.
The CRC-1023 controller can be used for several applications
with a measuring range from
The controller controls the defrost in the system based on time
based where the compressor is stopped. It is also possible to
select the interval between defrosts and a maximum time out
after which the defrost is interrupted.
There are safety features which include shutting down the
system incase of a fault from a pressure control or similar
device.
The CRC-1023 are single set point cold room controller. The
Sub-Zero CRC-1023 are aesthetically superior versions of
their predecessors.
A number of parameters are displayed alphanumerically to set
up the instrument for each specific function.
