I just hooked up a thermostat and every time the heat turns on the AC turns on, also how do you do you set cycle set 4.5 now. I had a friend tell me to move the Blue wire from the 'B' terminal and hook it to the 'G' terminal this is where we are now. The reason I had to move the Blue wire I'm sure you know. The blower had to be manually operated to have heat, l The thermostat , T101143/PSM40 Heat/ Cool. Wifes starting to bark that it's cold any help would be greatly appreciated. Thanks Steve.
