Zoning card for trane

9 years ago

For those trane experts out there, I have a tam7 variable speed airhandler with a xr17 2 stage outdoor heat pump unit with heat strip. I have 2 zones in the house and want to know if I need a 432 zoning card to properly run the unit. Currently I have a 322 operating two stages of heat and the aux heat strip. Is this correct? Thanks
