It’s easy to program your system for maximum energy savings. You can program four
time periods each day, with different settings for each day.
This thermostat is pre-set with energy saving program settings. We recommend these
settings, since they can reduce your heating/cooling expenses by as much as 33%.
(See next page to adjust times and temperatures of each time period.)
