Fan switch

Set the FAN switch to Auto or On.
In “Auto” mode (the most commonly used setting), the fan runs only when the heating or cooling system is on.
If set to “On,” the fan runs continuously. Use this setting for improved air circulation, or for more efficient air cleaning.

Press the temperature adjustment buttons until the temperature you want is displayed in the upper right portion of the screen.
Note: Make sure the SYSTEM switch is set to the system you want to control (Heat or Cool).

Built-in compressor protection

Honeywell Home-Pro-3000-Non-Programmable-Digital-Thermostat-FIG.6

This feature helps prevent damage to the compressor in your air conditioning or heat pump system.
Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait 5 minutes before restarting.
During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.

Battery replacement

Batteries are optional (for backup power) if your thermostat was wired to run on AC power when installed.
Install fresh batteries when the REPLACE BATT warning begins flashing. The warning flashes about two months before the batteries are depleted.
Replace batteries once a year, or before leaving home for more than a month. Batteries provide backup power to the display during power interruptions. All settings are permanently stored in memory and do not require battery power.
