15.10.1. Heat recovery ventilation (HRV)
PAA unit heating model operation in a system that includes HRV
The ported MXZ outdoor units continue to circulate hot gas through the PAA unit in thermal off. HRVs
may require the operation of the furnace blower in conjunction with the HRV when their fan is not powerful
enough to circulate the air throughout the house. The furnace blower operating while in thermal off mode
will cause the PAA unit to release a large amount of heat in the air flow.
The branch box MXZ continues to circulate a smaller amount of hot gas through the PAA unit in thermal off
in comparison to the ported MXZ outdoor units.
