HERMOSTAT
There are many types and styles of thermostats but the operation is
usually similar. BE SURE TO BECOME FAMILIAR WITH YOUR
THERMOSTAT. The simplest type of thermostat only starts and
stops the furnace to maintain the desired room temperature. The
most widely used types will control both heating and cooling func-
tions and will have a Fan Switch with Auto and ON settings. On Auto,
the circulating air blower will cycle on/off with the furnace but if
switched to ON it will run continuously regardless of whether or not
heating or cooling is being provided.
In addition, there are thermostats which automatically switch from
heating to cooling mode and those with night set back capability.
The night set back, or multiple set back, type allows for a different
temperature at night or during the day when no one is at home.
Programmable thermostats will allow for more control and tailoring
of the heating and cooling functions. The level of this control will
depend on the type of thermostat applied.

immediately follow the instructions on the cover of this manual.
If you do not smell gas after five minutes, move the furnace's
gas valve ON/OFF switch to the ON position.

3. Induced draft blower is de-energized following a 15 second de-
lay. The circulator blower is de-energized following a 60, 90,
120, or 180 second delay period.
4. Remove the burner compartment door.
5. Move the furnace's gas valve ON/OFF switch to the OFF posi-
tion.
6. Close the external manual gas shut-off valve.
7. Replace the burner compartment door.
Furnace lockout is characterized by a non-functioning furnace
(circulator blower may be running continuously) providing a one
flash diagnostic LED code. Lockout results when a furnace control
detects abnormal conditions. If the furnace is in "lockout", it may be
reset by any of the following methods:
1. One hour automatic reset. Control will automatically reset itself
and attempt to resume normal operations following a one hour
lockout period.
2. Power interruption. Interrupt 115 volt power to the furnace for
between 0 and 20 seconds.
3. Thermostat cycle. Interrupt thermostat signal to the furnace for
between 0 and 20 seconds.
If the condition which originally caused the lockout still exists, the
control will return to lockout. If your furnace frequently locks out, a
problem exists which must be corrected.
