FILTER REMINDER

 
Your thermostat logs the amount of time your heating and cooling 
system has been running and gives you a reminder when it's time to 
replace your filter.

" F I L

will be displayed every four seconds in the place of the 

time display when it is time to change you filter.  To clear the 
reminder, press the Prog key.  The display will return to normal in 10 
seconds.  Don't forget to change your filter! 

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.
