•For CoolMaster 4000M System Number must be 0, Unit Number must be 01-50
•For CoolMaster 1000D System Number must be in range 1-4
•For CoolMaster 2000S and 3000T System Number should not be 0

 

UID reflects the indoor unit Centralized Address. For proper operation of Cool Master all indoor units have to be given Centralized Address (depending on specific AC system type this can be done automatically by system or has to be done manually by integrator). You should refer to specific AC system manuals to find out how to set and quire Centralized Addresses.

 

Below are examples of accepted UID's.

Note: For backward compatibility  Unit number in System can be represented by hexadecimal numbers couple in range 00-0F equal to decimal 00-15. For example 10A represents Centralized Address 1-15. We recommend not to use this option in future designs.
