Wiring connection for a Ruud air handler & seeking...

posted by NCITTech on Jan 05, 2008


Can you tell me where I can get the wiring diagram/schematic for my Ruud heat pump, model number UHQA1210BNS. Had a water problem that caused the diagram on the inside panel for the electrical connections to become difficult to read. Tried gently cleaning diagram to remove the rust/dirt. It helped a little until part of the paper started to come off.

My immediate conern is to learn what the orange wire, coming out of the Ruud air handler (the unit inside the house), connects to. Either to the thermostat and/or the control cable going to the outside unit.

This is a 2nd posting. My 1st posting was a little unclear after I re-read it.
Thanks in advance,
Jerry

The orange wire coming out of the outside unit is for the reversing valve( controls the heat and cool mode of the ac) If its unhooked, it will be either in the ac mode all the time or the heating mode all the time depending on the style of the reversing valve. The orange wire goes to the (O terminal) inside the outside unit.

There is also another orange wire that goes from the air handler to the thermostat. One orange for the thermostat, and another to the condenser( out side unit)
