Temperature and Fresh Air Control
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 guess-
work out and put simplicity in. It's programming made easy.
