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.
