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 t " 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!
REAL TIME PRICING SYSTEM
Your thermostat may be configured to adjust its temperature settings
in response to changes in the cost of energy. Using this feature, you
can take advantage of your energy provider's rate structure without
sacrificing your comfort.
The thermostat can make adjustments for 4 energy rates: LO , MID ,
HI and CRIT (critical). At LO energy rates, the thermostat controls
your system as it normally would, with no variation for energy rates.
For each of the higher rates,
MID , HI and CRIT , you can easily set
the number of degrees of variation by changing the VAR (variation)
settings for the rate.
The rate currently in effect is provided to the thermostat by the
energy provider's meter or other device. The thermostat will raise the
cool setting or lower the heat setting by the amount that you select for
the higher rates. The thermostat display will show which rate is in
use by periodically flashing
RATE - LO , MID , HI or CRIT in the time
display.
The thermostat remembers your original settings, and will show them
if you press the up or down arrows to see the desired settings.
