Cleaning of ZT
The ZT unit measures 6.88 x 7.31 x 1.52 inch (175 x 186 x 39 mm), and
weighs 1.25 lb (0.57 kg). A coiled, 6-pin telephone-type cord is included.
The cord is 17 inches long and stretches to 5 feet. The ZT contains a
5-year lithium battery, factory installed.
The Wall Mount Base with ZT measures 6.94 x 7.44 x 2.00
(176 x189 x 51 mm).
The Utility Mount Base with ZT measures 6.94 x 7.44 x 6.00
(176 x 189 x 152 mm) when mounted on the ENC100.
Installation of the Zone Terminal must meet the following standards:
● Ambient operating conditions: 32 to 122°F (0 to 50°C)
● 10 to 90% non-condensing relative humidity
● 86°F (30°C) maximum dew point
Notes: Do not mount the Zone Terminal on a vibrating surface.
The atmosphere must be free of corrosive chemical vapors that
may damage electronic equipment.
● Use mild soap and water with a soft cloth to wipe surfaces of the ZT
clean.
● Do not immerse the ZT unit in water.
● Wipe clean with pure isopropyl alcohol, if surface becomes
excessively dirty.

Installing the
Zone Terminal
Considerations
Inserts
Before you mount the ZT or connect it to a controller, the clear plastic
insert that describes the displayed values must be in place.
1. To open the ZT, lay the ZT flat and press the white tab on the top of
the ZT while pulling the front cover towards you.
2. Align the insert to the lower left front of the ZT.
3. Press the pieces back together.

Figure 1: Template Installation
Connecting the
Wiring
Prior to final connection, the ZT must be downloaded using the ZT PRO
software tool which is part of the HVAC PRO Rev. 3.0 or later. Refer to
the HVAC PRO for Windows User’s Manual, Zone Terminal section.
If the ZT is connected 50 feet or less from the controller, install 24 AWG
(6-conductor) telephone cable between the controller and the ZT.
If the ZT is connected up to 500 feet from the controller, install 18 AWG
wire. The ZT requires 24 VAC, Common, and Zone Bus. The Zone Bus
and Common should be twisted pair.
The ZT can be connected directly to the:
● Air Handling Unit (AHU)
● Function Module Kit (FMK)
● Relay Kit (RLY) through a CBLCON-0
● Actuator (M100C)
● Zone Sensor (TE-6400)
● Humidity Sensor (HE-6400)
Figure 2 shows you where to locate the telephone-style plugs in these
components.

Installation
For office or other types of remote connections, attach the Wall Mount to
a flat surface or wall. Use three screws and plastic anchors (not
provided). For easy reading, mount the ZT at least 65 inches from the
floor to the top of the ZT.
1. Position the Zone Terminal Wall Mounting Base on the wall.
2. Mark the three mounting hole locations and remove the base.
3. Drill three holes for No. 6 anchors (not included) and install the
anchors for mounting the base.
4. Thread the ZTU cable through the access hole in the back of the base.
5. Secure the Wall Mounting Base to the wall with three No. 6 screws.
6. Plug the ZTU cable in the back of the ZTU, and snap the ZTU into
the base.
