I didn't know such a feature existed, I'll have to think about that. Thanks everyone for your help.

Let me take a stab at how this would function in my particular case: The duct system is kept somewhat biased towards the new addition. Shutters close it off when that zone's thermostat is...

How is it better than just slaving the addition?

I'm looking through some of Honeywell's zoning products. For example, the Honeywell Envirazone Control Panel advertises "Zone of Greatest Demand algorithm reduces and regulates HVAC cycles,...

Are there thermostats commonly available that will synchronize their calls for heat?

What does that mean, "slave it"?

Well, the internet cops had to show up.

I like how these threads spiral out of control. I have no intention of zoning my whole house. I just (potentially) want a step up from closing off a few registers in a small area that consistently...

Hypothetically, purely for my own intellectual curiosity: Can a Honeywell ARD or RRD (or something similar) be used manually to throttle back a small zone a bit. Isn't that what the "adjustable...

@HVAC_HUSKER: I totally understand where you are coming from but this has nothing to do with low bids and mickey mousing. Here's some more background: Super old house, historic, murderously...

Why can't one use the motorized zone damper as a balancing damper? Isn't that what the "adjustable range stops" are for?

How do you do that? Doesn't the register get opened and closed eventually by the occupants? How would one know what shutter position to return the register to?

So you would typically not install a balancing device?

Both the ARD and RRD models have "adjustable range stops". Is that what would be used to balance the system? In a new home that is fully zoned from the getgo, how is balancing accomplished? Surely...

To clarify, balancing dampers were never installed by my former contractor, they are non existent in the new addition. If something like a Honeywell ARD can provide both manual balancing and the...

Let me start over. The addition is already in. It gets way too much air from the furnace, the rest of the house is now too cold. Manual J and manual D will be done. Is there a motorized damper...

Are there duct dampers that provide both duct balancing and motorized on/off zone control? My hvac contractor would like to add some balancing dampers to the duct work that feeds a new addition. I...

Steve,

How does Tekmar handle non-hydronic heat sources? Suppose there is one zone with surface temp limited radiant flooring and second stage forced air, and then another zone with only forced...

Which zoning solutions provide synchronization to reduce equipment cycling? I see that Honeywell's Enviracom does, are there any others?

Hi HVAC-Talk members,

I would like to extensively zone an existing mixed hydronic and gas forced air heating system which is servicing my 1840's historic home and new addition near Grand Rapids,...
