Configuration
1. The control system is comprised of
a dual controller configuration:
a. T3C – larger controller.
Handles compressors
and staging.
b. Companion – small
controller. Handles
refrigeration circuits –
EXVs, Fans, etc. and
pumps. This entails more
IO then is available on the
small controller and
therefore, some functions
are sent to the T3C
controller to process.
c. This screen provides this
transfer of control from
Companion to the T3C for
Digital and Analog
outputs.
