●drill
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.

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

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.

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.

The Panel Unit in Poteau, Oklahoma has a bracket available for mounting
the ZT behind a window that allows control equipment to be mounted
behind the ZT, thereby maximizing the use of the UPM. Contact the
Panel Unit for more information.
Johnson Controls Panel Unit wires and configures units, complete with
accessories, to your specifications. The ZTU internal mounting bracket is
also available. Contact:
