INSTALLATION

Remove the security screw on the bottom of

Terminal Equipment C ontroller cover.

 Open unit by pulling on the bottom

side of Terminal Equipment
Controller (fig. 1).

 Remove wiring terminal s from sticker .
 Please read the FCC ID and IC label

installed in the cover upon removal of
cover for the wireless products.

Location

1. Should not be instal led on an outside
wall.

2. Must be installed away from any
direct heat source.

3. Should not be instal led near an
air discharge grill.

4. Should not be affected by direct
sun radiation.

5. Nothing should restrict vertical
air circulat ion to the Terminal
Equipment Controller.

Installation

1. Swing open the Terminal
Equipment Controller PCB to
the left by pressing the PCB
locking tabs (f ig. 2).

2. Pull out cables 6” out from the
wall.

3. Wall surface must be flat and
clean.

4. Insert cable in t he central hole
of the base.

5. Align the base and mark the
location of the tw o m ounting
holes on the wall. I nstall base in
the proper orientat ion. Arrow on
base should be facing up.

6. Install anchor s in the wall.

7. Insert screws in mounting holes
on each side of the bas e (f ig. 2) .

8. Gently swing back the circuit
board on the base and pus h on
it until the tabs lock it.

9. Strip each wire 1/4 inch from
end.

2 | VZ7260W Series- Installation Guide

10. Insert each wire according to wiring diagr am .

11. Gently push excess w iring back into hole (fig. 3).

12. Re-Install wiri ng terminals in their c orrect locations (fig. 3).

13. Re-install the cover (top side first) and gent ly push extra wire length back into
the hole in the wall.

14. Install security screw.

 When replacing an existing Terminal Equipment Controller, label the

wires before rem oval of the Terminal Equipment Controller.

 Electronic controls are static sensitive devices. Dischar ge yourself

properly before manipulating and installing the Terminal Equi pment
Controller.

 A short circuit or improper wiring may permanently damage the Terminal

Equipment Controller or the equipment.

 All VT7000 series Terminal Equipment Controllers are desi gned for use

as operating controls only and are not saf ety devices. These inst ruments
have undergone rigorous tests and verifi cation prior to shipping to ensure
proper and reliabl e operation in the field. Whenever a control f ailure
could lead to personal injury and or loss of property, it becomes the
responsibili ty of the user or installer or electrical system designer to
incorporate safety devices (such as relays, flow s witch, thermal
protections, etc…) and or an alarm s ystem to protect the entir e system
against such catastrophic failures. Tampering with the devices or
unintended application of the devices w ill result in a void of warrant y.

THEORY OF OPERATION

The VZ7260 series uses a Viconics proprietary adaptive logic algorithm to control the
space temperatur e. This algorithm c ontrols the heati ng and or air condit ioning system to
minimize oversho ot while still providing comf ort. It provides excepti onal accuracy due to
its unique PI time propor tioning control algorithm , which virtually eliminates t emperature
offset associated with traditional, differential-based On-Off thermostats.

• Access to mounting holes.

• Facilitates wiring.

Easy configuration and self-binding operation

• Easy configurati on w ithout using any special software or additional tools.

• Can be used as stand-alone or with supervisi on controller for monitoring purposed.

• Truly scalable i n terms of supported number of zones and RTU units.

WIRELESS SYSTEM OVERVIEW

Viconics VZ7260X5x00W Zone controllers are used in conjunction with the
VZ7656X1000W Roof Top Controller controllers. Combined, the y are designed for typical
single or multis tage RTU, HP’s and their associated local zones.

The Terminal Eq uipme nt Cont rol ler features a t wo-l ine, ei ght-character di splay. There i s a
low backlight level that is always act ive and can only be seen at night.

When left unattended, the Terminal Equipment Controller has an auto scrolling display
that shows the current status of the system.

Each item is sc rolled sequentially with the bac k light in low level mode. Press ing any key
will cause the back light to come on to high level.

Manual scrolling of each menu item is achieved by pressing the Yes (scroll) key
repetitively. The last item viewed will be shown on the display for 30 seconds before

they are the network masters for each VZ72 controller reporting to them.

• Wireless controller factory default Channel & PAN ID = Controller( s) offline

• VZ76 RTU controller is the network coordinator.

• Range of PAN ID on all controllers to use 251 to 500. This r ange is reserved for

stand-alone syst em operation.

Notes:
Each system with a VZ76 RTU master will use a uni que P AN ID and / or Channel settings.

When PAN ID is used with a range of 1 to 250, for (NS) Networked System s
In this applic ation, any controller( s) are simply router to t he system. The VWG / Jace-

Driver is the coordinators to the system. I.E. the VWG / Jace-Driver is the network
masters for ANY controller(s) reporting to them.

• Wireless controller factory default Channel & PAN ID = Controller( s) offline

• VWG Jace -Driver is the network coordinator

• Any controllers ( VZ72’s, VZ76xx RTU’s or any VT7xxx wireless controllers ) act

as routers.

• Range of PAN ID on all controllers to use 1 to 250. Reserved for networked
system operation.

Examples:

Notes:

• Each controller(s) to use same PAN ID and Channel as VWG Jace-Driver
coordinator.

• VWG / Jace-Driver supports network integr ation for required GUI / System /
