Honeywell RTH8500 Wifi Thermostat User Manual
Quick Installation Guide
Smart Response® Technology
This feature allows the thermostat to “learn” how long the furnace and air
conditioner take to reach programmed temperature settings, so the temperature
is reached at the time you set. For example: Set the Wake time to 6 am, and the
temperature to 70°. The heat will come on before 6 am, so the temperature is 70°
by the time you wake at 6. The message “Recovery” is displayed when the system
is activated before a scheduled time period.
Battery replacement
Batteries are required to provide power when common wire is
not used. Batteries are recommended to provide backup power
if common wire is used. Install fresh batteries immediately when
the low battery icon appears. The icon appears about two months
before the batteries are depleted.
Even if the low battery icon does not appear, you should replace batteries once a
year, or before leaving home for more than a month.
If batteries are inserted within two minutes, the time and day will not have to be
reset. All other settings are permanently stored in memory, and do not require
battery power.
NOTE: When replacing batteries, alkaline batteries are recommended.
