Hello,

My name is Billy. In the old thermostat can you tell me what the blue and the orange were on?

Hi Billy, the problem is I didn't see what the old thermostat was on. Had a new unit installed and the tech said it wasn't working properly because of termostat
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

Ok, Usually the blue wire is the reverse wire on a Rheem/Ruud.

Do you have access to the indoor blower unit?

HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

The issue is that blue can be used for common or B for reverse valve....and likewise orange is usually reverse valve for all other makes. We just need to see which of the 2 run the reverse valve

i have both orange and blue, the issue is right now the system is shutting down when I lower the termostat significantly to see it turn off
Customer reply replied 1 month ago
will do
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

I understand...that is why I need a pic of the wiring in the blower unit where thermostat wire attaches.

If...and that is if.....the installer used the correct wiring code...which most do not on Rheem/Ruud...I would say blue is O/B terminal set for B and orange is C or W2.

But with Rheem/Ruud we always need to see the wiring in the air handler

Thank you....there will be 2 thermostat cables....one from thermostat...and one from the outdoor heatpump unit.

They are pretty tight together in the pic...but does the blue wire from thermostat go direct to the wire from outdoor unit?

I am not sure how it connected outside
Customer reply replied 1 month ago
I suppose I can go outside and snap pictures of outside

Outside?
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

In the pic I cannot tell if it wires to a wire that terminates in the air handler or attaches to another wire that leapfrogs outside. But if you do get a pic of the thermostat wires outside it will automatically tell us which wire is reverse valve

Currently the system will not go off when I purposely lower the thermostat temp it continues to run, but when I set it off it goes off and when I set it to fan the fan seems to run alone.
Customer reply replied 1 month ago
Not sure how to determine wires that are going outisde
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

Ok from the pics...

Blue at thermostat should be in C like you have

Orange will be in O/B but programmed for B

The thermostat will also be programmed for heat pump

The white wire should be in W2

Ask Your Own HVAC Question
Customer reply replied 1 month ago
Okay will reconnect
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

If the unit still does not operate properly, it is somewhere in the wiring outside of the thermostat.

Moving the white to w2 will have the thermostat wired properly and programming it correctly for heat pump.

If issue remains it is NOT thermostat related

Ask Your Own HVAC Question
Customer reply replied 1 month ago
As for as the programming should I program heat to O, and what should I program cold to
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 1 month ago

Heat for B ( because it is Rheem/Ruud)
