Wireless PTAC Energy Management System
Easy Installation
Compatible with virtually any HVAC equipment,
the T9000 wireless energy management system
installs in minutes without the installation
difficulties and expense of wiring.
Energy Conservation & Comfort
Occupants often struggle to find and maintain a
comfortable room temperature. Moving thermostat
control out of the equipment and into the living
space where it belongs improves comfort and
saves energy. Studies have shown that precision
temperature control alone yields 10% or more in
energy savings, a unique circumstance where
both greater comfort and savings are expected.
Deep, sustained temperature setback of unsold
rooms saves even more. Each degree of setback
generates approximately 3% in energy savings. A
10 degree temperature setback saves 30%.
Wireless Network Solutions
Just by installing T9000 wireless thermostats you
get a wireless network for your entire building!
You do absolutely nothing, that’s how easy. No
routers, no data concentrators, no network
management hardware and no network
management learning curve either.
