Harmony IIIt Installation Setup Worksheets
G61MPV/G60UHVDual Fuel; with Honeywell 2−stage IFC control (Heat Pump applications)
Job Name: Indoor Unit Model: Outdoor Unit Model:
Miscellaneous Items:
- Install Pressure Switch in the outdoor unit per Harmony III installation instructions (27W13 for R410A or 21J18 for R22)
- Install Balance Point Sensor (56A87) as per installation instructions. Set to desired outdoor lock out temperature for HP
- Install Optional Defrost Tempering Sensor 67M41 (if used) per installation instructions. NOTE: MUST be located in coil delta plate between furnace and
coil
- Install Discharge Air Sensor per installation instructions. The location of the sensor is CRITICAL for proper system operation
Indoor Unit setup:
- 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)
- 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.
- Furnace IFC Control DIP switch settings (ON or OFF):
1 OFF (DIP switch 1 must be set to Off for 2−stage heating operation)
2 OFF (DIP switch 2 determines 2
nd
stage heat time delay & is ignored by Harmony III)
3 ON (DIP switches 3 & 4 determines heating blower off delay, recommended is 180 sec)
4 ON I
5 DIP switches 5 & 6 determines 2
nd
stage cooling blower speed or maximum system air vol.)
6 I
7 (DIP switches 7 & 8 determine blower adjust" setting for maximum system air volume)
8 I
9 OFF (DIP switches 9 & 10 determines cooling blower ramping profile & is ignored by Harmony III)
10 OFF I
11 OFF (DIP switches 11&12 determines heating blower speed & is ignored by Harmony III)
12 ON I
Harmony IIIt Panel setup:
- Heating staging jumper (circle one): 85 90 100 110 120 130 (Recommended 90 deg−F)
- Zone 1 PIAB 140F DAS jumper in place (circle one): Yes No (see install instructions for info)
- Cooling staging jumper (circle one): 50 55 60 (select desired discharge air temp during cooling)
- Cont. Air Reduction jumper (circle one): 0 25 50 75 (% airflow reduction for continuous fan operation)
- Heating Air Reduction jumper (circle one): 0 20 40 (must be set to 0% for heat pump systems)
- System Configuration jumpers (circle one): HP GAS (Set to HP)
- Stages (circle one): 2COOL 1COOL (Set to match condenser, 1 or 2 stage)
- Stages (circle one): 2HP 1HP (Set to match heat pump stages, 1 or 2 stage)
- E−HEAT Stages (circle one): DF 1 2 3 (Must be set to DF for dual fuel application)
- Desired total system cfm with all zones calling− _________ Total system cfm per tables− _________ Minimum cfm− _________
- Zone 1 – Name:____________ Desired cfm:____________ PIAB Setting: ____________% Actual cfm: ____________
- Zone 2 – Name:____________ Desired cfm:____________ PIAB Setting: ____________% Actual cfm: ____________
- Zone 3 – Name:____________ Desired cfm:____________ PIAB Setting: ____________% Actual cfm: ____________
- Zone 4 – Name:____________ Desired cfm:____________ PIAB Setting: ____________% Actual cfm: ____________
NOTEAll of the above are recommended starting positions for DIP switches and Harmony III jumpers. Slight variations may be required during sys-
tem start up and operation checks.
