lntroduction
The Zone Terminal is a hand-held or wall-mounted person/machine
interface for the Metasys Application Specific Controllers. It has the
versatility to connect to a controller in several ways, and allows the user to
monitor or adjust set points and time scheduling within a specific zone.
The Zone Terminal is used to monitor or adjust set points and for time
scheduling of occupied, warmup/cooldown, or shutdown zone conditions.
It connects to:
●a VAV/UNT through a TE-6100 Zone Sensor
●an AHU directly
●an AHU through a Function Module Kit or a Relay Kit
●an AHU or UNT through an M100C Actuator
The Zone Terminal is designed as an easy-to-use hands-on device with
which you can:
●quickly identify an alarm and its location
●monitor and adjust up to 18 analog points
●monitor 18 binary points
●extend a daily time schedule using Occupied Extend
●add or modify daily, holiday, and temporary time schedules
For specific Theory of Operation details, refer to the Zone Terminal
section of the HVAC PRO User’s Manual.
The ZT uses a liquid crystal display (LCD) divided into three sections
from top to bottom. Each display includes:
●five, seven-segment digits
●decimal points
●colon
To the left of the display are 18 cursors (●) and triangles (▲), 6 per
display. The cursors indicate current position in the respective display.
When flashing, the triangles indicate an alarm condition in the
corresponding analog points.

Displays
4 Zone Terminal
The right side of the ZT display includes 18 pairs of binary indicators—a
bar ( | ) for On, and a circle (❍) for Off. These symbols flash when the
respective binary point is in alarm.
Five LED’s located in the bottom panel include four green Mode
Indicators and one red Alarm Indicator. The Alarm Indicator LED flashes
when any analog or binary point is in alarm.

Zone Terminal 5
●AHU, UNT, or VAV controller with 24VAC transformer
●AS-ZTU100 Zone Terminal comes with a 6-pin telephone-style coiled
cord. Also included are four inserts: one Time Schedule Overlay
(remove the paper backing), and three clear inserts with set point labels
(remove protective plastic backing).
Note: The UNT/VAV inserts match common configurations right out of
the box. The ZT matches the most-used AHU configuration:
Mixed Air Single Path.
●TE-6100 Zone Sensor
●AS-FMK100 Function Module Kit
●AS-RLY100 Relay Kit or M100C Actuator
●AS-ZTUWMB Wall Mount Base
●AS-ENC100 Enclosure
●AS-ZTUUMB Utility Mounting Base With Screws
●AS-ZTUBAG Carrying Case
●AS-CBLPRO-1
●IBM compatible computer or laptop
●WS-SWHPRO-3 HVAC PRO Release 3
●clear overhead transparency film for the customized inserts
●AS-CBLCON-0 or AS-AHU101 and AS-FMK100
!
CAUTION: The ZT must be plugged into a 6-pin telephone-type
jack. Plugging the ZT into an 8-pin jack destroys the
8-pin receptacle and prevents the ZT from powering
up.
Note: AS-CBLPRO-1must be used to download the ZT.
AS-CBLPRO-0is not compatible for downloading.
ZT configuration and downloading are done with a software program
called ZT PRO which is part of the HVAC PRO software, Rev. 3. This
easy-to-use tool configures, commissions, and downloads the ZT’s data
base. The program runs on an IBM® PC/XT/AT, PS/2, or any 100%
compatible computer. Figure 2 is an overview of the ZT configuration and
downloading process. Refer to the HVAC PRO User’s Manual for specific
information on configuration and downloading the Zone Terminal.

!
CAUTION: Any changes in the configuration of the AHU and
UNT/VAV must be up-dated in the Zone Terminal.
Failure to download the ZT after configuration
changes to the AHU and UNT/VAV prevents access
to the ZT Operating Modes.
The following section presents options available for hardware connections
necessary to complete the downloading process. The section includes:
●Using AS-CBLCON-0 or
●Downloading Without an ASC Controller (using AS-CBLCON-0) or
●Job site Downloading with a UNT or VAV (using AS-CBLCON-0) or
●Job site Downloading Without AS-CBLCON-0
Use AS-CBLCON-0 for multiple connections of related equipment. The
switch on the AS-CBLCON-0 must be in the download position. The red
LED is indication of 24 VAC power. The green LED shows Zone Bus
transmissions from the controller. If this LED is off, the Zone Bus wire is
open. If this LED is ON solid, the Zone Bus is shorted to COMMON.
