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 ZTs, the installation process includes setup of the ZTs. This
setup results in a customized ZT that monitors and controls a selection
of points in a particular controller or group of controllers. The setup,
diagrammed in Figure 1, involves both a decision process and a
configuration process:
•
The decision process--determines the best way to customize the ZT
template, time schedule, and decimal place.
•
The configuration process--creates files and links an application
specific controller’s configuration to a specific ZT file.
Configuration requires ZT PRO software, which is part of the
HVAC PRO™ software package.

Zone Terminal and ZT PRO Software
The ZT PRO software tool is part of the HVAC PRO software
package. ZT PRO sets up files, based on a previously configured
controller or controllers, and then downloads the files to a Zone
Terminal.
The Zone Terminal is a hand-held or wall-mounted person-machine
interface 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.
Application Details
The Zone Terminal is used to monitor or adjust setpoints and for time
scheduling of occupied, warmup/cooldown, or shutdown zone
conditions. ZT PRO software establishes the ZT parameters for the
controller’s analog setpoints and values.
After downloading the ZT from the ZT PRO, the ZT connects to:
•
a VAV/UNT/PHX 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
Theory of Operation
The parameters established with the ZT PRO make the Zone Terminal
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
7
Zone Terminal
Displays
The ZT uses a Liquid Crystal Display (LCD) divided into
three sections from top to bottom (Figure 2). Each display includes:
•
five, seven segment digits
•
decimal points
•

Design Considerations
The decision process requires that you consider the characteristics of a
particular HVAC (Heating, Ventilating and Air Conditioning) system,
the objectives of the system users, and the responsibilities of the
system maintenance personnel (the ZT users). With these
considerations in mind, you must decide:
•
Which controllers require a dedicated ZT for maintenance
personnel access?
•
Which controllers can be grouped for access through a common
ZT?
•
How are controller points and operations organized for viewing
convenience?
•
What names and adjustment capabilities are appropriate through
the ZT display access?
•
Does control access through each ZT require security, and should
such security be divided into two levels?
Notes:
These decisions are interactive. Before making any of these
decisions, review all of the considerations involved with
each decision. If practical, also discuss the implications of
these decisions with the ZT users.
Each time a controller configuration is altered, the ZT must
be redownloaded. Therefore, program the ZT after all
controller configurations are complete and stable.
The ZT presents false or misleading information if changes
are made to the controller configuration after the ZT is
downloaded.
Single Controller vs. Multiple Controller Display
Decide on the number of ZTs required for the HVAC system, and
decide which controllers will be accessed by each ZT display.
Considerations are:
•
The control requirements of the user--most users prefer simple
controls that allow them to easily solve ordinary problems. A full
range of control capabilities may not be helpful or useful. Provide
just enough control to solve ordinary problems. Note that the
definition of ordinary is site dependent.
•
ZT capabilities--refer to Table 2 for the number of displays and the
range of controllers and the points accessible through each display.
Determine the minimum number of ZTs required to meet the
control requirements.
12
Zone Terminal
•
Convenience--a dedicated ZT mounted right on a critical AHU in a
large installation provides quick access and eliminates the need to
find and bring the correct ZT to do a task.
•
Cost--provide good value. Reconsider the convenience and control
requirements against the total number of ZTs required.
You can configure each ZT with up to three different controller
applications. For each application, you can:
•
Select the specific controller points available for display and
control.
•
Access points in only one type of controller: AHU, VAV, UNT, or
PHX.
•
Configure for access to controllers that have:
-
a single, specific configuration by using the single controller
display
-
up to 12 different configurations by using the multiple
controller display
Single Controller Display
Use the single controller display for complete access to a controller.
With the single controller display, you can:
•
Select any points in the controller, although the number of points
available through each display is limited.
•
Schedule the controller.
Multiple Controller Display
Use the multiple controller display for limited access to several similar
controllers. With the multiple controller display, you can:
•
Select up to 12 controller configurations.
•
Select only points common to the specified controllers.

Display Type Summary
Table 2 summarizes the capabilities of the ZT display types.
Table 2: Display Types
Consideration
Controller
Characteristic
Display
Single or
Multiple
Controllers
Each ZT can be configured for up to
three applications. These can be a mix of
single controller or multiple controller.
Controller
Access
Single
Controller
Each single controller application is
automatically encoded so that it can access
only one controller configuration. Controllers
with identical configurations can be accessed
using a single controller display.
Multiple
Controller
Each multiple controller display can access up
to 12 controller configurations. All controllers
accessed by a multiple controller display must
be of the same type AHU, VAV, UNT, or PHX
controller.
Scheduling
Single
Controller
Each ZT can schedule just one controller.
Networked ASCs cannot be scheduled using
the ZT. Standalone ASCs require a ZT for
scheduling.
Points
Single
Controller
Any points in one controller configuration can
be accessed.
Multiple
Controller
Only points common to all the selected
controller configurations can be accessed. The
only exception occurs when all selected
controller configurations are Single Duct. In
this instance, all points are accessible.
Occupied Extend
Occupied Extend is a special feature that lets you temporarily extend
the occupied mode of operation without going into the Time Schedule
mode.
If the system uses the Occupied Extend feature, it must be listed as
one item on the template (insert).
No matter what Begin/End time is scheduled for the current day, the
user decides how long the system should remain on. For example: it is
currently 3:30 p.m. and the user wants the building to stay on until
11 p.m. This is an extension of 7 hours and 30 minutes, which is
entered on the ZT.
Any amount of time from 00:00 to 23:59 can be entered in Occupied
Extend.
14
Zone Terminal
Enable Occupied Extend
You can enable occupied extend control of a controller from the ZT if:
•
The controller is accessed through a single controller display.
•
Time Schedule files are defined for the controller.
•
The controller connected to the ZT is not part of N2 Network.
To enable this function, select the Occ Extend point from the list of
analog setpoints when defining the Single Controller Display.
Organizing Points
Arrange binary points using the following considerations:
•
Group logically by function.
•
Organize consistently relative to other facility ZTs.
•
Organize consistently relative to analog point organization.
Arrange analog points using the following considerations:
•
Locate related points in separate display groups so that these points
can display at the same time.
•
Organize consistently relative to other facility ZTs.
Organize points in the AHU ZTs so that related points can be viewed
simultaneously. For example:
•
outdoor air
•
discharge air
•
zone temperature
Also locate setpoint values and actual measured values in separate
display groups. This setup makes a display, such as Figure 4, possible
during troubleshooting.

In this case, various commands can be checked, such as the cooling
command, to determine why the discharge temperature is higher than
the setpoint.
Since the binary point values are always displayed, group them by
functions, such as the modes of operation--OCCUPIED,
SHUTDOWN, and WARMUP.
Renaming Points
For the ZT user, you can:
•
Change the point names displayed at the ZT.
•
Define the significant decimal characters for each analog value.
•
Enable adjustment of an analog point value.
•
Limit the range of adjustment available on an analog point.
•
Enable alarm on a binary point state.
16
Zone Terminal
Security Levels
Evaluate security requirements of the facility to determine if a
password is appropriate. Use both password levels if ZT users have
distinctly different responsibilities or capabilities.
The ZT can be configured to limit user access to the setpoint adjust
and the time schedule modes based on a 3-digit password.
Two passwords are possible per ZT:
•
The first provides full access to all modes.
•
The second password locks out access to the Time Schedule mode
and allows setpoint adjustment.
•
The user can also select no password, which allows access to all
levels.
Note:
The factory default password is 246.

Zone Terminal
Single Controller Display
You can configure a ZT display for control of a particular controller.
The process starts with the controller’s configuration file. From this
file, define a single controller display file. Later, when defining the ZT
load file, include this display file.
Note:
ZT PRO does not read Configuration files that have been
created by the DOS version of HVAC PRO. You must
recreate pre-existing DOS based Configuration files using
HVAC PRO.
Multiple Controller Display
You can configure a ZT display for control of up to 12 controller
configurations of a given type. The process starts with selection of the
configuration files for the controllers. The ZT PRO assembles a
temporary file containing points common to all controller
configurations. From this file, you define a multiple controller display
file. Later, when defining the ZT load file, you include this display
file.
Load File
Once you have created the display and schedule files for a ZT, build
the load file. You must define the display files used (up to three), the
weekly and holiday schedule files used (one each, if any), some
hardware data, and the access passwords.
Load File Download
Once you have created the load file for a ZT, download the file to a
ZT. The process requires physical connection of the ZT and
HVAC PRO PC (Personal Computer), selection of the load file, and
the download command.
When downloading the ZT without a controller, 24 VAC power must
be accessed from a transformer. Where power is accessed through an
XFR100 transformer, splice the wire coming from the transformer
according to Figure 6. This is only required when you do not have an
AHU, VAV, UNT, or PHX controller available. Refer to Zone
Terminal Technical Bulletin (LIT-6363014) in the Metasys Application
Specific Controllers Technical Manual (FAN 636.3) for other
hardware connections for downloading.
Figure 6 summarizes the physical connection of the ZT to your PC.

Analog Points
Only points selected as adjustable in the ZT PRO can be adjusted with
the ZT.
Points are adjustable within the limits defined by ZT PRO.
If an analog point has a setpoint that is outside of the ZT PRO defined
adjustable limits, when the user tries to adjust the value, the ZT, upon
the first adjust key press, goes to the value corresponding to the limit.
The user cannot make adjustments outside of those limits.
If a point is selected in the ZT PRO as being adjustable, but does not
flash when selected on the ZT, an N2 or Zone Bus laptop is overriding
the point.
The ZT displays analog values based on the following priority:
Table 4: Analog Values Priorities
Priority
Value
Priority 1
Override from N2
Priority 2
Command from N2
Priority 3
Override from Zone Bus laptop--race condition with N2
Priority 4

20
Zone Terminal
If an N2 overrides a point while the user is adjusting it, the N2
overrides the point. The user is allowed to finish the adjustment, or
save or discard the adjustment. The point is not adjustable until the
override is released. The ZT displays the overridden value.
Only AIs report alarms. Alarm limits are determined by HVAC PRO
not ZT PRO. How the point was defined with HVAC PRO is how the
alarm triangle works on the ZT. Controller points which are displayed
on the ZT show an alarm if the point is unreliable. This occurs only if
the user enables the alarm reporting for the AI (Analog Input) with
HVAC PRO.
ADFs cannot report alarms.
AOs cannot report alarms.
If an AI is overridden by N2 or a Zone Bus laptop beyond the alarm
limits or the unreliable limits (sensor limits), the triangle for this AI
flashes on the ZT.
Point adjustments in ALL cases are made to the controller’s E2 PROM
and are permanent.
Binary Points
Binary points can be BIs, BOs, or BDs. Binaries can never be adjusted
or commanded. They are read only.
Display rules and priorities are the same for binaries as for analogs.
See priorities as listed in the Analog Points topic in this section.
Alarms for binaries are different than for analogs.
•
BOs do not report alarms.
•
BIs report alarms, and the conditions for alarm reporting are set by
HVAC PRO.
•
BDs also report alarms at the ZT, and the conditions are set by the
ZT PRO.
•
The user defines whether a binary is to have alarm reporting
enabled. The normal (non-alarm) state is also defined by the user.
•
When an alarm-enabled binary point in the ZT is not in its normal
state, the binary will flash on the ZT. When the binary returns to its
normal state, the binary will stop flashing on the ZT.
•
If a binary is commanded or overridden by N2 or a Zone Bus
laptop to a non-normal state, the binary flashes if the point is
alarm-enabled.

Passwords
The ZT PRO allows the user to enter none, one, or two passwords.
If the user does not enter a password, access is given to all the ZT
modes of operation. Note, however, that if the ZT is not configured for
time scheduling, the user is denied access to time scheduling.
One password is for adjust privileges only. The other password is for
adjust and time scheduling privileges.
A user can enter the same password for both levels and be allowed
access to both adjust and time scheduling.
A feature of the ZT called Idle Key Timeout is set at the ZT PRO,
which tells the ZT to return to Monitor mode and cancel the user’s
access (forcing re-entry of the password) after the keyboard remains
idle for the specified period of time.
Time Scheduling
You can configure a ZT for weekly and holiday schedule control of
one controller configuration. Schedules require a single configuration
display on the ZT.
The following rules apply to time scheduling:
•
The Zone Terminal reads and compares only one Begin and
one End time for the current day.
•
Once Midnight is reached, the next day’s schedule takes over.
•
One Begin and One End time for each day must be scheduled for
Occupied, Warmup, and Shutdown.
•
If no transition is desired for one entire day, enter 00:00 Begin and
24:00 End to keep the controller On (Occupied) for that day. If you
want the controller Off (Unoccupied) for the day, enter
24:00 Begin and 00:00 End. This procedure applies to Occupied,
Warmup, and Shutdown.
•
When the Begin and End times are equal or entered as 24:00 or
0:00, that mode will not execute.
Time Scheduling can only be used on a single controller configuration.
That is, the ZT is expected to be dedicated to the controller, which is in
need of time scheduling.
Time scheduling commands are written to the E2PROM locations of
Occupied, Warmup, and Shutdown, and are permanent. Therefore, do
not remove the ZT from the associated controller when time
scheduling is in use.
The user can schedule any combination of Occupied, Warmup, and
Shutdown based on availability in the controller configuration.
22
Zone Terminal
Availability in the controller configuration is defined as having the
desired point (Occupied, Warmup, Shutdown) as a writable BD
(Binary Data) point in the configuration. Hardware BI (Binary Input)
points are not schedulable.
If a user is scheduling a controller via external hardware clock to the
controller’s hardware BI, the user must reconfigure the controller’s
download to make the schedulable hardware BI a BD point.
The initial schedule for the associated controller can be originally
specified at the ZT PRO and modified at the ZT.
Since the precision of schedules is specified in Hours and Minutes, the
schedule activation is +/- one minute. This means that if a user is
watching the ZT clock, and sees the time roll over to the start of a
scheduled event, it may be up to one minute before the user sees the
system switch states.

Time Scheduling works in one of two modes: Local and Network.
Local
The ZT is standalone with a single controller.
The schedule for running the controller is in the ZT.
!
CAUTION: Do not disconnect the ZT from the controller
during time scheduling. The last state in the
controller is retained forever.
Network
In Network scheduling mode, the ZT assumes that the scheduling
commands are coming from the N2 Network headend. When
configured with this option at the ZT PRO, the ZT never allows access
to the Time Scheduling mode.
Disconnecting the ZT in this mode has no affect on the controller’s
operation.
Zone Terminal
23
Occupied Extend
Occupied Extend is an extension of time scheduling.
Occupied Extend is only available to standalone configurations with
Occupied as a BD.
Occupied Extend is only operable when time scheduling is operable.
That is, if the user picks Occupied Extend as one of the analog points,
and the controller that the ZT is plugged into is not the one designated
as the time scheduled controller, the ZT does not allow the user to set
an Occupied Extend time.
The user sets an Occupied Extend duration. This duration is measured
in hours, minutes, or both. The duration is measured from the time it is
entered by the user. For example, assume it is 3:00 p.m. (15:00) and
the occupied schedule is Occupied until 6:00 p.m. (18:00). If the user
wants the building to stay occupied until 9:00 p.m. (21:00), the user
would set Occupied Extend up for 6:00 (6 hours, and 00 minutes).
The ZT can be downloaded with three configurations in one download.
Theoretically, the user could select (via the ZT PRO)
three configurations so that each has Occupied Extend. Since only one
of the three configurations can be linked with the time scheduling
when plugged into the other two controllers, Occupied Extend is
therefore not adjustable.
Timekeeping
Timekeeping works with or without an N2 Bus present and needs no
user intervention except to set the time and date on the ZT.
The time in the controller is updated by either the N2 or the ZT. The
N2 has the highest priority.
There are three clocks to be synchronized in the system:
•
controller clock
•
ZT clock
•
N2 clock
If there is an N2 online, it updates the clock in the controller. The ZT
synchronizes its clock to the controller time so that all are the same.
If there is no N2 online, the ZT sends its time to the controller to keep
it synchronized with the ZT.
Anytime the ZT is powered up, it waits five minutes before setting or
synchronizing the clock in the controller. However, time scheduling
updates continue uninterrupted.
Anytime the ZT senses the N2 going from Offline to Online, the ZT
waits five minutes before synchronizing its clock so the N2 has time to
update the time in the controller.
24
Zone Terminal
When N2 is online, it controls the time and, therefore, the ZT does not
allow adjustments to time or date. These items become read only.
Since the controller holds the N2 Comm status for ten minutes after
N2 really is no longer present, the time and date in the ZT cannot be
modified during this ten minute duration. After the time expires, the
time and date can again be modified.
If the N2 comes online while the user is adjusting time or date, the ZT
allows the user to complete or discard their adjustment. The N2 takes
over and prevents further adjustments to time and date.

If trying to communicate with a PC:
- Ensure CBLCON switch is in the download
position.
- Ensure you are using an AS-CBLPRO-1 or
AS-CBLPRO-2.
- Check connections from PC serial port to
CBLPRO and CBLCON to ZT.
- Check to ensure you are specifying the
correct serial port in the ZT PRO.
- Reinitiate download at ZT PRO and view
operation.
- If the ZT still doesn’t communicate, try
connecting directly to a controller to
eliminate some of the cabling variables.
If trying to communicate with a controller:
- Ensure CBLCON switch is in the normal
position.
- Ensure the controller is properly mounted,
connected, and powered.
- Replace the cable between the ZT and the

ZT time or date does not
match the N2 Network
device.
Periodic update rates in the
ZT can cause
inconsistencies (plus or
minus two minutes) between
updates.
When connecting a ZT to a
controller on the N2
Network, or when the ZT
loses communication with
the controller, there is a five
minute delay for the ZT and
the N2 Network to
synchronize time.
During times near Midnight,
the ZT date may be off by a
day for up to one minute.
This is normal. When a new
time is sent to the controller
from N2, there is a one to
two minute delay in the new
time displaying on the ZT.
This is normal.

User wants the time of day
to display on the ZT even
when it is not in use.
Time of day clock display is
desired.
Ensure Time Scheduling is set up in the ZT
and that the ZT is connected to the Time
Schedule controller.
Using ZT PRO, set the keyboard idle timeout
field to zero (0). This disables the timeout
feature in the ZT. Redownload the ZT with the
revised load file.
When you finish using the ZT, go to Time
Scheduling mode and set the time up in
Display. The time remains on the display until
another user interacts with the ZT.
Note: The ZT still has adjust privileges
enabled.
ZT stays Occupied after
Occupied Extend expires.
The extend time has expired
and the schedule has taken
over, but the schedule is
now in Occupied, or doing
nothing.
Ensure the ZT schedule is as desired. If the
schedule for Occupied is disabled (Begin and
End times equal) when the Occupied Extend
time expires, the ZT reverts back to the
schedule. Since the schedule is inactive,
Occupied remains on.
ZT jumps back to Monitor

Meaning
Action
Time Schedule binaries
(Occupied, Warmup,
Shutdown) are changing
while the user edits the ZT
Time Schedule.
The schedule is being edited
during the day of the week
or holiday that is active, and
the present time is in the
window of adjustment.
Make day of week schedule changes at times
other than during the desired Begin/End times.
For holidays, change the date so that it is not
the current date. Edit the schedule, then set
the desired date for the schedule.
Entering 0 0 0 does not
disable access to Time
Scheduling or Adjust modes.
Auto Access Enable is in
use.
In the ZT PRO, add password to your load file
and redownload the ZT.
ZT does not disable
passwords and return to
Monitor mode after an
extended period of time.
Keyboard Idle Timeout
feature is not enabled.
With ZT PRO, change the Keyboard Idle
Timeout Value to the desired non-zero value
and redownload the ZT.
When building a load file for
the ZT, an error message
appears because the
ZT PRO detects that the ZT
cannot identify the proper
insert number for a particular
controller.
The same configuration file
is used in more than one of
the selected display files on
the Load File Data form.
Two matching controllers
have similar Path selections.
Continue editing the Load File Data form and
remove one of the conflicting display files.
Abort the form and create a new single display
file for the configuration, or a new multiple
display file that is applicable.
Continue editing the Load File Data form and
remove one of the conflicting display files.
Abort the form and create either a single
display file for the conflicting configurations or
create a multiple display file that uses the
conflicting configurations.

Introduction
This section describes ZT programs that cover both typical
applications and a wide range of situations. Use these examples to
illustrate the decision process or as templates for solutions to similar
situations on your installations.
Example 1-Setup for Typical AHU Job
Given the following situation:
•
Maintenance personnel travel from bank branch to bank branch
responding to complaints.
•
The bank branches are two story buildings, each with two air
handlers.
Table 10: Example 1 Values

•
For Monday through Friday, schedule from 7:00 to
19:00 for occupied, the remaining hours for
unoccupied.
•
For Saturday, schedule from 7:00 to 14:00 for
occupied, the remaining hours for unoccupied.
•
For Sunday, schedule all hours for unoccupied.

Example 2-Setup for Multiple VAV Job
Given the following situation:
•
The facility has approximately 500 VAVs in 3 different VAV
configurations.
•
The ZT user is a balancing contractor, so access to cfm setpoints is
a requirement.
•
A test file (the multiple controller display file using the three VAV
configurations) confirms that all points are common between the
configurations except the parallel fan cfm setpoint and fan output
command.
Table 11: Example 2 Values
Element
Example
Display
Configuration
Decisions
Configure the ZT with a single controller display for each
VAV configuration.
Point Selection and
Organization
Decisions
Use the same point arrangement for all three displays,
except one display has an additional binary point (FAN
STATUS) and another display has an additional analog
point (PAR FAN CFM). Figure 28 shows the point
arrangement.
With this point arrangement, the parallel fan
configuration file can be used to generate the label for all
three applications. This one label works for three
configurations, because it includes all of the point
configurations.
No data appears on the ZT for Fan Status or Fan CFM
parameters if the ZT is plugged into VAV controllers that
do not have these points.
