Hi all,

I'm planning to have a Honeywell dual zone system nstalled in a two-
story 2400 sq ft home. Their will be a thermostat on each floor.
I've read that a bypass duct isn't required in this type of
installation. Is this correct?

I recall seeing an episode of "Ask This Old House" where not having a
bypass duct was the cause of some overpresure issues. Unfortunately,
I don't recall the size of the home or the number of zones.

Thanking you in advance,
Orlanzo

So you want us to guess how this system is designed?

You dont. When the zones start shutting down the ductwork just
explodes.
Your Welome in advance
