I would like to upgrade my 4-zone heat pump system (Dual Fuel) to a new 4-zone controller. My question is... will a Honeywell HZ432 Zone Controller allow me to eliminate the systems current TAYPLUS 103 Fossil Fuel kit for a much simpler control package? I would like to retain all of the two stage functions of the XL1800 and XV80.

My current system:
Trane XL1800 Heat Pump and air handler
Trane XV80 Gas Furnace
TotalZone TZ-3 Zone Control Panel
TotalZone Add-a-Zone Panel
Fossil Fuel Kit TAYPLUS103A
AprilAir Dampers
White Rodgers 1F82-51 Thermostats

Apparently yes: https://www.forwardthinking.honeywell.com/related_links/zoning/truezone/install/69_2070_01.pdf

Remember you'll need the outdoor air sensor.
