Have a Payne A3PZ airconditioner and a Roberts Aire thermostate need help with wireing it up. The was I understand is that you need a Payne therostate to use with Payne AC unit. But surely there is a...
No, Payne is a cheap Carrier unit. Keep track of your wires and what terminals they are attached to. Usually, units are either a 4 wire or 5 wire setup. In either of these the R terminal is your 24v power, G term is your fan, W is your heat, and Y is your cool. Some times there is a 5 wire which is your common. You use a common if your thermostat isn't powered by a battery. On the R terminal, they are usually marked RC/RH and have a jumper between them. The only time you should remove the jumper is in a 5 wire set up. RC refers to the common and RH refers to Hot or power. Make sure that when you are installing the new tstat there is usually a very small switch that you change for either an electric unit or a gas unit. Change according to what you have. As long as you keep track of your colors and terminals on your old tstat, you won't have to open up your unit to see where the wires are terminating. Good luck to you!
