Finally a commercial thermostat made with building operators in

mind. Your customers will benefit from maximum comfort and

energy savings.

The i-Series thermostats received the 2003 Frost & Sullivan award for

simple, menu-driven programming that is similar to a cell phone.

Plus you can set optimal fresh air control to meet ASHRAE Indoor Air

Quality Standards. We have also added an adjustable purge control

to bring in fresh air occasionally during periods of non-occupancy.

The 9920i is compatible with all standard 24 Volt AC heat pump

system, up to two-stage heat and two-stage cool. We took the guesswork

out and put simplicity in. It's programming made easy.
