TYPICAL QUESTIONS

7. My thermostat has ENRG SAV
and SYSTEM lights. Why do they
both go on at the same time?
(For example: during the sleep
period.) During Programmed Recovery, when you recover gradually to a next set
point, you will stay in the energy-saving mode until the next programmed
time is reached. But the system will operate intermittently to
gradually
raise the temperature to your desired comfort level before the time you’ve
set as your WAKE time. You will always be saving energy until the next
period’s
actual set point is reached.
9. Sometimes my thermostat
doesn’t allow the house tem-
perature to drop to my SLEEP
setting before it starts bringing
the furnace on. Why? When you start your SLEEP period, the thermostat will turn off your
furnace and your house temperature will start to fall. After that, the
thermostat is out of the picture until the house temperature falls all the way
to your SLEEP temperature setting or until recovery starts.
In mild weather or with good insulation, your house temperature may not
fall all the way to your SLEEP temperature setting and the thermostat
won’t turn on your furnace until the time to recover back up to your comfort
setting.
8. Why don’t all thermostat
models have AUTO (automatic)
changeover from heating to
cooling? Most parts of the country don’t have wide temperature swings during a
24-hour period, so it is not necessary.
