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.

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.
