Hello, Do you have E and Aux connected with a short jumper?
The terminal is labeled Aux/E, not aux. My mistake.
My manual shows the connector Aux/E It actually shows Aux with a line under it and the E below the line (Like a math division problem).
Function 1 is set at 0
There is a W terminal, yes. There is currently an orange wire in that slot.
I have a gas furnace in the basement and an "air conditioner" away from the house in the backyard. Is that the same as a heat pump? It is what comes on for our air conditioning. Sorry about my lack of knowledge.
My wires are actually as follows:
Red - R/C
Yellow - Y
Orange - W
Green - G
White - Aux
It is an Amana RCC48A2B
This corrected the problem. All working properly. Thank you for your help.
