Very happy with this item. It came on the day promised. Removal of the old unit and replacing of the new unit took about an hour only because I labeled each wire but when I powered it up, it was business as usual. I live in a climate that gets very cold, so it came right on time. Thank You.

The product is marked as resideo logo. Initially I thought this is a fake item. After Google the relationship of these two companies, I tealized they resideo bought some honeywell product lines. So this produce has resideo logo, still produced by previous honeywell.It would be better to clarify this in product description.

It looks like the one I need but haven’t installed yet. It is for my hot water boiler. Looks exactly like the Honeywell but is not.Sorry I’m not much help.

Not a Honeywell like the part description said it was. A resideo is the part received. Have not installed yet. Don’t know if it works yet. Not pleased

Resideo acquired Honeywell lines a number of years ago. (I know, because my company is a Resideo Premier Dealer). Resideo continues to develop and manufacture under the 'Honeywell Home' line.For alarm systems, the Resideo name is on the commercial units..while the exact same panels are branded as "Honeywell Home" when sold to residential customers.Honeywell still makes FireLite and Notifier panels..but the Honeywell 128FBPT panels are actually manufactured by Resideo. I know it's confusing. Many who work with these parts every day also are confused.But rest assured, the Resideo labeled parts are legitimate.(FYI, Resideo also recently acquired First Alert)
