OPERATING MODES
Two operating modes are included: Monitor and Adjust.
Monitor Mode
As soon as the ZT is connected, it completes a self-check, and starts up in the Monitor Mode.
Monitor Mode lets you view up to three of chiller settings/sensed values at a time.
To allow you to monitor your system, a clear plastic Insert (factory made and installed) relates the
ZT’s output to your McQuay Global UNT controller.
