fan goes off and on with the cooling equipment.
In heating, the fan may start a few minutes after
the heating equipment comes on.

1. To lower the temperature setting, press the ▼key.
When in the heating mode, lowering the temperature
at night or during the day can lower your energy
costs.
2. To raise the temperature setting, press the ▲key.

Energy Savings
You can save energy with this thermostat in the heating
mode by lowering the temperature setting 5°F (3°C) to
10°F (5°C) at night and during the day. You can also save
energy in the cooling mode by raising the temperature
setting during the day before you leave for work or school.
Savings can be as high as 7% to 33% depending on your
home, where you live, the number of energy saving periods
you choose and your energy savings temperature settings.
If you like saving energy, but would like your thermostat to
automatically change the temperature setting, you might
want to consider purchasing the Honeywell Chronotherm®
Programmable Thermostat. With this thermostat,
temperature settings can be conveniently programmed to
automatically save energy.
