VARIABLES
DATABASE
The BMS or supervisory system and the address card
communicate through a fixed set of variables, also called address
numbers. Hereafter, you will find the information you need about
the digital, integer and analogue variables that the BMS or
supervisory system can read from or write to the chiller’s address
card.

Note
These chillers have two PCBs: PCB A & B.
PCB A: general parameters and circuit 1 parameters
PCB B: circuit 2 parameters
If a parameter is marked with X in column of PBC A or B, then the
parameter is present on the marked PCB.
