ANTICIPATION
Your thermostat has a sophisticated control system designed to keep
you comfortable while saving energy. Part of the control system is a
feature called "anticipation", which anticipates the need to turn the
system on or off before the temperature is actually at the setting.
As humans, we perceive temperature as a combination of heat in the
air and heat radiated from the walls and surroundings. The
thermostat also measures a combination of air and wall temperature.
When heating, the air temperature rises faster than the wall
temperature. The thermostat will turn the heat off briefly to prevent
overheating the air while the wall temperature catches up. Your
comfort is assured without overshooting the heat setting, which
wastes energy.
In summer, the thermostat will periodically run the cooling system to
circulate the air and remove humidity when the temperature is close,
but not above the cool setting. You will be more comfortable at a
higher cool setting, which saves energy.
Remember to allow some time for the thermostat to adapt to a new
setting.
