Humidification / Dehumidification Control
We’ve combined humidity and temperature control in one
easy-to-install, easy-to-program package. This versatile thermostat
provides control over both humidification and dehumidification. 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 9851i thermostat combines all the award winning features of our
9700i series thermostats with the convenience of humidity control.
When used in conjunction with our 9025i outdoor sensor, the 9851i
minimizes condensation and maintains optimal comfort. We’ve even
added a calibration feature to fine tune the thermostat to the
individual's unique environment.
The 9851i is compatible with most 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.
