NOTES:
For single-stage cooling applications, a jumper may be
required between Y1 and Y2 at the furnace control in order to
achieve the desired single-stage cooling airflow. Consult the
Blower Performance charts to determine if the required
single-stage cooling airflow can be delivered at low stage (Y1
input) or high stage (Y2 input). Additionally, use of ramping
profile and dehumidification features require a jumper
between Y1 and O and Y1 and DEHUM, respectively.
Thermostat R required if outdoor unit is equipped with a
Comfort Alert TM module.

A single-stage thermostat with only 1 heating stage may be used
to control this furnace. The application of a single-stage
thermostat does not offer true thermostat-driven 2-stage
operation, but provides a timed transition from low to high fire.
The furnace will run on low stage for a fixed period of time before
stepping up to high stage to satisfy the thermostat's call for heat.
The delay period prior to stepping up can be set at either a fixed
5-minute transition time or a load based variable time between
1 and 12 minutes (Auto transition). If the Auto transition mode is
selected, the control averages the cycle times of the previous
3 cycles and uses the average to determine the time to transition
from low stage to high stage.
To use a single-stage thermostat:
1. Turn off power to the furnace.
2. Move the thermostat selection DIP switch to the Off
(single-stage) position.
3. Set the desired transition time by setting the Stage Delay DIP
switch to On for Auto transition, or Off for 5-minute transition
time.
4. Turn on power. Refer to the following illustration.
