1. Configuring the Zone Terminal Introduction The Zone Terminal ZT is a hand held or wall mounted Person Machine Interface PMI for the Metasys Application Specific Controllers ASCs It has the versatility to connect to a controller in several ways and allows the user to monitor or adjust setpoints and time scheduling within a specific zone This application note provides an overview of the setup functions and configuration of the Zone Terminal This document describes how to start ZT PRO create a single controller display file create a multiple controller display file define analog points for a display file rename analog points for a display file define binary points for a display file rename binary points for a display file save a display file print a display file print a clear insert delete a display file create a weekly schedule file save print or delete a weekly schedule file create a holiday schedule file print or delete a holiday schedule file Zone Terminal create a load file select display files for the load file select schedule files for the load file complete and save the load file print and delete load files download a program to a zone terminal Zone Terminal 5 Key Concepts About This Document This section of the HVAC PRO User s Manual describes the setup process required for downloading the Zone Terminal If an HVAC Heating Ventilating and Air Conditioning system includes ZTs2.
