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.
You can simultaneously monitor the chiller in three ways:
• Monitor up to three settings/sensed values. A maximum of six items are accessible in each of the
three displays.
• Read the symbols to the right of the display numbers to learn the on/off status of various inputs,
outputs, or modes (| = On status; m = Off status). This provides continuous monitoring of 18
different status (on/off).
• Monitor alarm status–a flashing red alarm light and any flashing symbol ( |, m, s) visually notifies
you when your chiller has an alarm condition.
Adjust Mode
In Adjust Mode, the ZT displays information in each of the three numerical displays. Typically, the
displays are set up so that the relationship between the values can be viewed simultaneously. For
example:
Display 1 = Lvg Water Temp
Display 2 = Lvg Water SP
Display 3 = % Unit Load
This operating mode allows you to adjust any flashing setpoints. Setpoints adjusted by the ZT
remain in effect until you change them.
