Wiring connection for a Ruud air handler & seeking its wiring diagram.

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

    Please see the following link for INSTALLATION INSTRUCTIONS for Rheem Air Handlers: http://www.acdirect.com/xcart/images/pro...

    I totally agree with Daniel Philipps who said, "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"

    In MOST Heat Pump Thermostat wiring configurations, the following RULE OF THUMB is followed by HVAC Technicians: At the Thermostat: O = ORANGE = Reversing Valve .... W = WHITE = Heat .... R = RED = + 24 Volts DC from Transformer .... Y = YELLOW = COMPRESSOR .... G = GREEN = FAN (AIR HANDLER) .... C = BLUE = COMMON .... E = BLACK = EMERGENCY HEAT

  • Ed Riggle Sr Sep 20, 2012

    And, at the AIR HANDLER, in MOST Heat Pump Applications, the wires NORMALLY get connected as follows: G = GREEN = FAN .... W = WHITE = HEAT (AND GETS CONNECTED WITH THE WHITE WIRE GOING TO THE OUTDOOR UNIT capped with WIRE NUT) .... R = RED = + 24 VOLTS (AND GETS CONNECTED WITH THE RED WIRE GOING TO THE OUTDOOR UNIT capped with WIRE NUT) .... Y = YELLOW AND ONLY GETS CONNECTED WITH THE YELLOW WIRE COMING FROM THE THEREMOSTAT TO THE OUTDOOR HEAT PUMP UNIT with a WIRE NUT ... O = ORANGE = REVERSING VALVE AND ONLY GETS CONNECTED FROM THE WIRE COMING FROM THE THERMOSTAT TO THE OUTDOOR HEAT PUMP UNIT and is capped with a WIRE NUT) .... C = BLUE = COMMON (AND GETS CONNECTED WITH THE BLUE WIRE GOING TO THE OUTDOOR UNIT capped with WIRE NUT) .... E = BLACK = EMERGENCY HEAT AND ONLY GETS TERMINATED TO THE EMERGENCY HEAT STRIPS WITHIN THE AIR HANDLER.

    The WIRING DIAGRAM on your OUTDOOR Heat Pump UNIT should have the WIRING DIAGRAM on how IT SHOULD be connected. It is usually located on the inside panel of the electrial compartment.

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)

I'm a Certified HVAC Technician and have been working in this industry since 1996. I simply went too www.google.com and typed in RUUD HEAT PUMP WIRING DIAGRAM, and found the following website URL where you can view and download and print your own PDF copy:
https://www.google.com/search?q=ruud+heat+pump+wiring+diagram&hl=en&prmd=imvns&tbm=isch&tbo=u&source=univ&sa=X&ei=5b5aUNyLAuXa2QW0h4CIBw&ved=0CB0QsAQ&biw=1366&bih=576


But, for your information, in MOST cases, standard COLOR Coded WIRING for HEAT PUMP applications shows the ORANGE wire gets landed onto the "O" Terminal on the Heat Pump Thermostat, at the AIR HANDLER both ORANGE WIRES simply get twisted together and capped off with a WIRE NUT, and the ORANGE WIRE on the OUTDOOR UNIT also gets twisted together with the ORANGE WIRE coming down from the AIR HANDLER UNIT and capped off with a WIRE NUT. Therefore, O = Orange Wire = Reversing Valve. Good Luck

WIRING THE THERMOSTAT TO AC UNIT THEN FROM THE UNIT TO HANDLER


Generally, you would go from the thermostat to the air handler, and then, from the air handler to the outdoor unit. I don't know if you have a heat pump or not, so I will give you a simple diagram and you can contact me if you need more.

Thermostat : Y G R W and sometimes C
Air handler: Y G R W and C
Outdoor unit: two wires connecting to the contactor ( not heat pump)

Thermostat; Y--------------Y(air handler cooling)------------------one side of contactor, outdoor unit
G-------------G (air handler, fan)
R--------------R (air handler ,hot)
W-------------W (air handler, heat)
C--------------C (air handler, common)------------other side of contactor, outdoor unit

This is a typical wiring diagram. Just contact me if you have something different. Hope this helps. Stay cool. mark

Themostat problem no power


Your R terminal in your air-handler is the 24v power that goes to the tstat. Look at the air-handler and match the color wire. ALL tstats have a power wire going to them. If you aren't getting power, you probably have a break somewhere in the wiring close to the thermostat you are replacing.

RUUD HVAC UNIT - HEAT STRIPS COME ON WITH THE A/C


What you are talking about I think are the strip heaters in the Air Handler this must be a Heat Pump system right??? If so please check your thermostat and make sure it is not in EMRGY HEAT mode.. One other note there is a 2 stage bulb system inside the stat if it is too cold outside and the heatpump on its own cant keep up with the call for heat the 2nd bulb closes and turns on the heater as a supplumnetal heat also these will come on or should come on when the unit goes into defrost.. plz let me know what it is you are trying to test and i can walk you thru it.. Also need a model # off the A/H to get a Wiring diagram

Wiring Diagram for Ruud Heat Pump


Unfortunately, the wiring diagrams for heat pumps are not so easy to come up with. The outdoor unit will have its own diagram, but may not include the indoor air handler and will probably not include the thermostat. That said, the orange wire is commonly run from the thermostat to the reversing valve in the outdoor unit. This wire is usually not connected to the indoor airhandler. The orange wire is usually used in a unit that has the reversing valve energized in cool. Ruud, however has its reversing valve energized in heat. Probably not useful but maybe helpful
