OPERATING SEQUENCE
HEATING
1. The thermostat initiates the heating cycle activating the controller and the
elements of the rst heating stage. The blower starts at low speed and at the same
time the rst two elements turn on. Their respective indicator lights display
heating element activity.
2. Approximately 10 seconds after the rst two elements activate, the other
elements turn on in sequence, one at a time. The blower fan increases speed as
each element turns on. After all elements are active the controller enters into
automatic modulating mode (if selected) maintaining a comfortable delivered air
temperature.
COOLING
The thermostat activates the air conditioning cycle. The blower starts at cooling
speed and the A/C condenser is activated. After approximately 7 minutes of
cooling operation, the blower speed adjusts to the latent cooling mode to
maximize dehumidication. This cycle is cancelable at the dipswitch on the
furnace controller if conventional high speed sensible only cooling is preferred.
The selection of the modulation or non modulating function must be performed by
a qualied technician.
WARNING;FAILURE TO FOLLOW PROPER PROCEDURE MAY
RESULT IN SERIOUS HARM OR DEATH.
MANUAL CONTROLS (g 1)
The POWER option and CONTINUOUS FAN switches are located on the fur-
nace upper panel.
When the POWER switch is set to “MAX”, all heating elements are operational.
When the POWER switch is set to “MODERATE”, the furnace operates at re-
duced heating capacity. This option is best suited to spring and fall conditions or
periods of low heat demands.

3
REMEMBER, during the winter months, this switch should be in the “ON”
position to insure heating demand is satised.
The POWER switch must be set in the “MAX” position when a
2 – stage thermostat or outdoor thermostat is installed and used to control the
electric elements of the second stage.
The “CONTINUOUS FAN” switch turns the blower on to continuous “LOW”
speed. This feature will lter the air and provide for better distribution in the
building.
Manual Furnace Controls
FAULT INDICATORS
The two left hand element LEDS also serve as fault indicators.
Should the airow be restricted by dirty air lters, these two LEDs will ash to
indicated poor air ow. Simply turn off the furnace and replace the lter with one
the same as the original equipment and restart the furnace. The fault condition
should reset.
CIRCUIT BREAKER
The circuit breaker is located at the right hand side of the front control panel
In the event that the fan motor or external device failure, the circuit breaker may
trip.
Only a licensed technician should investigate the fault condition.
Pushing in the white button will reset the breaker. If the button fails to remain
depressed, the fault condition may still exist.
Contact your service technician.
