Coleman 7900-6821 New Thermostat Question
Posted: Tue Jul 26, 2011 7:54 am
Hello Bob:
My system worked fine with an old 2 wire thermostat and the heater works fine with the new lux 1500 thermostat except the AC is not hooked up. I have all of the wire colors at the thermostat and at the Unit but the rest are not hooked up.
My thermostat now has the red and white wire hooked up and a jumper from RH to RC.
When I want my AC on I switch the unit sw. from HEAT to COOL and all is fine just no thermostat.
I hooked the yellow wire in the thermostat - where does the other end of the yellow wire go on the unit?
The compressor is properly connected to the Grey and Yellow wire for the unit and the system blower works when I switch to COOL.
I tried hooking my yellow wire to the other yellow wire... and then I bought a new transformer because I burnt the primary open. Bummer.... It works fine now like it used too.
I just want to set my cooling on a thermostat.
Any ideas... thanks in advance.
