Auto-Zone Control Systems EZ-Zone to Auto-Zone Upgrade Guide (Version 01C) - Manual (Page 4)

EZ Zone/Auto-Zone
4 Upgrade
The York International Corporation’s EZ Zone Controls
System was first introduced in the early nineties. The
EZ Zone Controls System was designed for York, by
WattMaster Controls, as a simple zone control system
for York’s line of commercial unitary roof top and split
system HVAC units. Since its original design and in-
troduction, the York EZ Zone Control System has
changed very little.

The Auto-Zone Controls System was created from the
original EZ Zone Control System concept by redesign-
ing, enhancing and expanding the original systems ca-
pabilities under the new Auto-Zone Controls System
name.
WattMaster’s Auto-Zone Control Systems have contin-
ued in the York EZ Zone tradition of keeping the con-
trols simple to install and use while enhancing the sys-
tem to make it more applicable and in line with the needs
of the current marketplace. In addition to offering an
excellent control system for zoning applications, the
Auto-Zone Control System has been expanded to al-
low control of multiple single zone constant volume
units and other devices such as lighting, exhaust fans,
and unit heaters.
Upgrading your EZ Zone system to the Auto-Zone Con-
trols system allows you and your customer to take ad-
vantage of the many improvements that have been made
in the Auto-Zone Controls system without having to
replace all the EZ Zone system components that are
installed on your job.
This guide is intended to provide you with simple
instructions on upgrading an existing EZ Zone system
to an Auto-Zone Control System.
