See the guide on how to twin R32 units on Goodman Non-R32 Furnaces. There is also the bulletin that applies to this as well.

NOTE: This is an incomplete manual, not showing the connections of the Dragonfly completely.

Additionally, electrically following the operation and sequence of events, (As shown in this wiring) the blower is not activated if Dragonfly #2 is in alarm.

A request for clarification has been requested.

Part number:

X72-362 0230K00007 ZONING KIT

 

Scenario 7:

Two R-410A furnaces paired with R-32 outdoor units - no accessories or zoning.

Parts needed: (2) Furnace Integration Kits and (1) PCBCM0313S.

Furnace 1 (powers the thermostat): Ro Terminal from Furnace Integration Kit control board 1 is wired through the accessory relay on the zone/accessory board to the thermostat.

Furnace Integration Kit 1 Enters Mitigation:

• Furnace Integration Kit control board removes 24VAC from R of the thermostat connector – Thermostat signals are removed (zone/accessory board status is unchanged)

• Furnace 1 runs blower Tap associated with Y + Y2 + G inputs and tells Furnace 2 to do the same via twinning communications

• After Mitigation, 24VAC from Furnace Integration Kit control R is returned, system goes back to normal operation.

Furnace 2: Furnace Integration Kit control board 2 will control the zone/accessory board via it’s on-board ALARM TERMINAL Furnace Integration Kit control board 2 Enters Mitigation:

• Furnace Integration Kit control board 2 Energizes Alarm Terminal and opens the accessory relay

• This disconnects the 24VAC signal between Furnace Integration Kit control board 1 to the thermostat – Thermostat signals are removed.

• Furnace 1 runs blower Tap associated with Y + Y2 + G inputs and tells Furnace 2 to do the same via twinning communications.

• After Mitigation, the Alarm Terminal is turned off, zone/ accessory board returns to a normally closed status and system goes back to normal operation.
