Temperature and Humidity Control.
We’ve combined humidity and temperature control in one
easy-to-install, easy-to-program package. Your customers will enjoy
the maximum comfort and energy savings, and you will benefit from
the time and effort saved by installing a single device that does the
work of two.
Our 9800i series thermostats contain all the features and benefits of
our award-winning 9700i series*, including our simple, menu-driven
programming that’s similar to a cell phone. Plus, you can set the
thermostat to maintain optimal comfort and minimize condensation
(requires optional outdoor sensor 9025i). We’ve even integrated a cali-
bration feature to help tune the thermostat to your unique environment.
The 9820i is compatible with all standard 24 Volt AC heat pump
systems, up to two stage heat and two stage cool. We took the guess
work out and put simplicity in. It’s programming made easy.
