If you look on the install manual. It says it will work for a heat pump without backup heat. No heat strips.........If you do not have strips the guide says as follows
"PLACE A JUMPER (PIECE OF WIRE) BETWEEN Y AND W IF YOU ARE USING A HEAT PUMP WITHOUT AUXILIARY/BACKUP HEAT." if this dosnt work check the fuse in the air handler you may have blown it if you did not turn the unit off before installing.
There is a contact in the blower control card that can stick on. There is also a possibility that the green wire which starts the blower motor could be shorting out with the red wire somewhere inside the thermostat wire. If that is the problem, either pull new thermostat wire, (the rest of the insulation is probably breaking down) or there is some new red link controllers from Honeywell that will completely eliminate wire because the controls are all wireless.
r is red c is blue w is white y is yellow g is green o is orange w2 is w2 is also white e is brown but some installers dont follow that pattern so maybe this helps red is 24voltpositive c is 24voltnegative yellow is compressor white or w2 is heat brown is emergency heat orange is reversing valve green is fan
The aux switch is for electric heat banks installed in the air handler. Depending on the outside temp. it may not be efficient to run in heat pump mode but in aux. or emergency would run the electric heat in the air handler.
Check to see if you have the system switch accidently on em. heat. The way you have it wired is correct except for the having brown on e. disconnect brown wire and cut ofbare end just in case they have the wire hooked up for constant run on roof.
I just had a new unit installed and I am surfing for troubleshooting tips too. My unit is doing the same... cools well heat sucks. my problem has been isolated down to the reversing valve... It is constantly energised which means it is constantly in a/c mode even when kicking on the heat strips... We disconnected a line at the thermostat and it is working well as a heater now. You may want to check yours to see if it is actually kicking over into to heat mode... -rob
