Have HVAC Questions? Ask an HVAC Expert for Answers
Hello, has this situation just begun or has the upstairs always been hotter than the downstairs.
Is there just one AC unit sitting outside on the ground or two.
Is there a 10 x 12 x 3 inch thick 'zone controller' box anywhere.
Tell me a lot about your technical skills so that I can help you most efficiently.
We can go from there.
Thanks. with these new electronic thermostats wiring errors can be made that affect zone systems. The upstairs thermostat in some cases can be wired to act as a master lock out thermostat so that the heat will not come on unless the upstairs is in heating mode, you would not have noticed that function, but its a key function and it works in tandem with the other thermostat.
Send me a photo of the zone controller box with the door open so I can see all the wire connections and the two loose wires.
I will mark it up with trouble shooting instructions.
Ooops the picture of the zone controller came though, no need to send another one I will mark this one up for you
Sorry for the delay we had a rush of emergency calls
I dont see the fuse on this diagram, is there a legend nearby
that shows a fuse?
If the 3A fuse is removable check it with an ohm meter... if you meant the 30A fuse I need to find it on the wiring diagram, so far I do not see it on the wiring diagram, do you see it on the wiring diagram.... there should be a legend printed on the same sheet of paper as the wiring diagram that gives the full name of each component next to its abbreviation used on the diagram
Do I have it correctly then, that the 30 amp fuse is not shown on the wiring diagram?
This is typical of much of the chinese equipment, wiring diagram does not match what they have installed, making trouble shooting difficult if not impossible... same with that non removable fuse.
That is their phone number call them on monday and ask whats up with the non removeable fuse and the wiring diagram without a legend and the fuse not shown on the diagram.
Hello again, our server computers are messed up badly, they have locked me out of responding to you, and posted my last 3 messages to you that were intended for another customer.(the Klimaire posts) We will have to wait a while, maybe a few hours for the engineers to sort that out.... this is the first time this has happened in the last 5 years
Hopefully JA management will have this server mix up corrected by tomorrow
Our server is still messed up apparently, I will try to work around it,
you typed earlier
Top:Thermostat @ 60Black and Red = 27.4Black and White = 0Thermostat @ 80Black and Red =27.3Black and White =0Bottom:Thermostat @ 60Black and Red = 27.4Black and White = 0Thermostat @ 80Black and Red =27.3Black and White =0
The dampers should be open when black and red are powered, locate the dampers physically and see if they are both open, you can compare one against the other to determine which is stuck, since both are getting power to black and red both dampers should be in the same position.
Dampers will be in the duct work, under the house or in the attic as the case may be, sometimes they are at the discharge air end of the furnace, these are fit into 10" diameter ducts in most cases, sometimes larger,
You can test them by reversing the red and white wire connections they should reverse positions when you do that, if one of them does not reverse, its bad.
Once we get this sorted out it will be time to locate the "finish and rate" link, that is the only way the company pays me for my time, thanks, ***** ***** I will leave the question open for any follow up that you might need.
