Thank you for your recent purchase of an Aprilaire
®
Communicating Thermostat. With this
purchase, you have invested in the highest quality thermostat currently available.
This Model 8870 Communicating Thermostat operates similarly to a conventional thermostat but
has the unique capability of being controlled, either locally or remotely (from a home automation
system). The Model 8870 thermostat is capable of integration into your home automation system
or independently operated with the Aprilaire Model 8825 System Controller.
Note: This manual covers basic operation of the thermostat,
which may be altered by the home automation system setup.
