MULTISPAN CC-552 Owner's manual

  • Hello! I've reviewed the operating manual for the Multispan Cooling Controller CC-552. This manual details the device's dual-relay compressor control, adjustable temperature setpoints, hysteresis, probe calibration ,and time delay settings. It also covers how to avoid compressor overload, secure the keypad, and use the parameter interchange. I'm here to answer your questions about the device and its operation.
  • What is the temperature range of the controller?
    How many relays are available for compressor control?
    What is the default setting for the temperature difference to restart the compressor (Hysteresis-1)?
    Can the keypad be locked?
    What is the time delay between compressor restarts set to?

This function is used to switch on 2 comp.
st
when 1 comp. can’t achieve lower setpoint.
Example
if SP1=10°C & SP2= 12°C & T2=10 min.
If T2=0, this function will not active.
If T2=0, then T2 Will always greater than Td1 &
Td2 (Relay ON Delay Time)
In above condition, when com1 is not able to
achieve 10°C for a period of 10 min then after
nd
10 min 2 comp will also start and both comp.
will cutout at the lower setpoint 10°C.
T2 PARAMETER
It is a minimum time delay between two successive
cutout of both comp.
Example
T3=10 sec.
This function is used to avoid overloading of any
comp. working at over period of time. this function
will interchange each other parameter (hysteresis,
setpoint & relay delay time).
Example
T4= 4 hour
For T4= 4 hour, setpoint, hysteresis & relay delay
time will interchange after 4 hours
st
For T3=10 sec when 1 compressor turn off then
nd
2 comp. will switch off after 10 sec.
If T3=0 this function will not active
T3 PARAMETER
T4 PARAMETER
Time calculation will start at power on.
This function will help by not overloading any one
compressor for long hours and increases
compressor life.
If T4= 0 hours, then this feature will not activate.
