We have a 2 year old furnace, with every bell and whistle. We have 12
year old duct work with some special features. We have two
thermostats, one upstairs, one downstairs. When the upstairs draws,
the bottom does not, and vica versa. When both draw, the upstairs is
shut off. This is all done with "relays" and is a pain for the
installer, technication, etc. This controls 3 "big valves" that
The salesman did not tell us about a "module" that would do all the
work of the "relays" simpler and cleaner. I feel the furnace company
should put the "module" in for free labor, with me paying for the
"module". If the salesman had told me about the "module", I of course
would have said put it in. It has cost about 50 hours in non-billed
work so far, over the past 2 years.
What do you experts think?
If its 2 years old, it sure does not have every bell and whistle...
Honestly, I dont have a damn idea what you are talking about. Relays?
Are you talking about a modulated damper system? 3 dampers controled by
relays with only two thermostats?
No..I dont think so...not even with a Honeywell $900 multi zone controller
If you are talking about a zone controller, they cost quite a bit, and NO, I
dont think the company should put it in free. It sounds like you went with a
cheap company to start with...perhaps not in price, but in workmanship, and
now you have problems. Professional opinion....get someone familiar with
zoning in, expect to pay for his time to look the system over and make a
suggestion, and pay whatever it takes to get your unit in order.
You havent explained what the real problem is, havent really given any
information at all, other than you want something for free 2 years after the
IF the techs you have now dont understand what is going on, then you have
either: The wrong techs, or the wrong system installed. Either way, the fix
is to find new ones.
IF and ONLY IF you had complained to the company during the first...say...90
days, then sure...they would be almost obligated to put the unit in for no
cost, other than full retail or even a slight savings on the controller, but
its not their problem now. You waited 2 years. You accepted, and paid for
what they put in TWO FRIGGIN YEARS ago.
No...they dont owe you a thing.
About 12 years ago I specified a system for my home that is now sold by
Trol-A-Temp, a component of Honeywell, to do what you are describing. I
have 4 zones implemented and 2 spare expansion zones. My system is
forced hot air but that doesn't preclude using it for hot water. Go to
Honeywell's web site and search for "MABS 2". Trol-A-Temp used to call
it MABS II (Mastertrol Automatic Balancing System II). The whole
package fits in an enclosure about 8 x 10 x 2 inches for the first 4
zones and another similar, but smaller enclosure for the expansion relays.
It sounds like you have a non-standard system, and the service men that are
attempting to service have to analyze the circuitry of the add-on before
they attempt to make any decisions concerning servicing. You would be well
served to get a schematic of this add-on, with the locations of the electric
dampers in the duct system, and how it interacts with the actual furnace
system. Then, when someone comes to service it, they can just go over the
schematic and the damper locations and then corelate this to the furnace.
It will be a time saver, and thus, a cost saver.
