Job Name:
Indoor Unit Model:
Outdoor Unit Model:
Miscellaneous Items:
9 Install Pressure Switch in the outdoor unit per this instructions (27W13 for R410A or 21J18 for
R22)
9 Install Balance Point Sensor (10Z23) as per this installation instruction. Set to desired outdoor
lock out temperature for HP
9 Install Optional Defrost Tempering Sensor 67M41 (if used) per installation instructions. NOTE:
MUST be located in coil delta plate between furnace and coil
9 Install Discharge Air Sensor per installation instructions. The location of the sensor is CRITICAL
for proper system operation
Indoor Unit Setup:
9 Cut on-board link W914 DEHUM OR HARMONY (R to DS) on furnace IFC control (if not cut,
fuse will blow in zone control board)
9 Cut and tape wires from pin # 2 and pin #13 on plug J46 of the VSM wiring harness routed from
the motor to the Furnace Integrated control.
9 Furnace IFC Control DIP switch settings (ON or OFF):
DIP Switch ON or OFF

9 OFF
10 OFF
11 OFF
12 ON
Condition
DIP switch 1 must be set to OFF for two stage heating
operation
DIP switch 2 determines second stage heat time delay
and is ignored by Harmony III zoning system
DIP switches 3 and 4 determines heating blower off
delay, recommended is 180 sec
DIP switches 5 and 6 determines second stage cooling
blower speed or maximum system air vol.
DIP switches 7 and 8 determine blower "adjust" setting
for maximum system air volume
DIP switches 9 and 10 determines cooling blower
ramping profile and is ignored by Harmony III zoning
system
DIP switches 11 and 12 determines heating blower
speed and is ignored by Harmony III zoning system
