Sending MVs to the
G3ZA
The G3ZA's unit number and model determine which MVs are sent from the
EJ1 to the G3ZA.
G3ZA Models with 4
Channels
The EJ1 uses the G3ZA's unit number to determine whether to send heating
outputs or cooling outputs.
Note With a TC2, the Channel 3 and 4 MVs will be set to 0.0%.
G3ZA Models with 8
Channels
The following outputs will be sent whether the control method is set to stan-
dard or heating/cooling control.
Note (1) When standard control is being used, the Channel 5 to 8 MVs will be set
to 0.0%.
(2) With a TC2, the Channel 3, 4, 7, and 8 MVs will be set to 0.0%.
MVs Output from the
G3ZA
The outputs of predetermined channels are set in the G3ZA's MV, but any MV
can be output to multiple channels by setting the G3ZA's “Source Channel.”
Arithmetic operations can also be executed on each MV.
