12.Setyourthermostat to the temperature that satisfies your
comfort requirements.
SUGGESTION: Setting the thermostat back a few degrees
and compensating for the difference with warmer clothing
can make abig difference in your fuel consumption. The few
degrees at the top of your thermostat "comfort level" are the
most costly degrees to obtain.
When the room temperature drops below the temperature selected
on the thermostat, the furnace will switch on automatically.
When the room temperature reaches the temperature selected on
the thermostat, the furnace will be switched off automatically.
Some thermostats have a FAN mode with 2 selections: AUTO
and ON. When set on AUTO, the furnace blower cycles on and
off. In the ON mode, the furnace blower runs continuously.
Continuous fan keeps the temperature level in your home more
evenly balanced. It also permits the indoor air to be continuously
filtered. With the unique feature Fan On Plus'_, the blower speed
can be increased or decreased if desired due to change of seasons,
large gatherings in your home, etc. Simply change your FAN
from ON to OFF for 1 to 3 seconds (or AUTO depending on
your thermostat), and then return to ON. The blower will switch
to the next higher speed. There are at least 3 speeds to choose
from. If the blower is running on its highest speed, a request to
change will direct the blower to return to its lowest speed.
If you own an Evolution Control, simply push the "fan" button
to change the fan speed.
