Zoning With Carrier Infinity Furnace


I have a MVP 58 Carrier furnace (with a variable speed blower).

I'm wanting to install a Honeywell HZ322 zoning system. The HZ322 unit provides a signal to lower the blower speed when only one damper is open. The HZ322 instructions indicate that the "lower blower speed" signal should be connected to the DHUM terminal on the furnace.

The Carrier instructions don't have much on the DHUM signal and what is said all has to do with running in cooling mode.

Anyone know if that signal will do what I want (i.e. to lower the blower speed) and/or if I have to configure the furnace in some way to get it to work?

Thanks.

Zoning With Carrier Infinity Furnace


You may want to check out the carrier zoning that is designed to operate with the infinity furnace. Not sure how that Honeywell will interface with the infinity.
