The CRC-1200 is a panel/wall  mounted controller dedicated to 
controlling the cold room and its various devices. 

The  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. 

It is also possible to select the interval between defrosts and a 
maximum time out after which the defrost is interrupted. The 
same probe which controls the defrost cycle is also used to 
control  the  evaporator  fans.Post  drip  and  condensor  fan 
control are amongst many other features in this contoller.

There  are  safety  features  which  include  shutting  down  the 
system  incase  of  a  fault  from  a  pressure  control  or  similar 
device.

Computer Connectivity over RS485 and Remote 
monitoring(Optional).

Single Operation Quick Freeze Mode(Press UP Key for 4 sec), 
Set system in quick freeze mode which is time based for that 
period  new  setpoint  will  be  lower  than  running  setpoint  and 
system will try to achieve that setpoint, after time period over 
set point will be normal setpoint.
