Hi, my AC fan blower is staying on all the time. When in "heat" mode the fan comes on only when the heat is called for. The thermostat is a six month old LUX Atx1500 that I replaced.
thanks...ed

Does the fan turn off if you remove the stat G ?

I don't have a conductor on "G", just Y,W,RH,O & RC.
Should I have a 'G'?

I pulled the wiring out of the wall a little to check the wiring colors and found that one wire(black) is not being used. Only the Yellow(W), Orange(Y), Red(RH) and Green(O) were connected on the old thermostat and so I only used those conductors when I installed the new one. Should the black be used?

The O terminal will always be energized in cooling mode. Move your green wire the the G terminal.

I moved the wire from 'O' to 'G' and the fan appears to only run when the AC has asked for it or it is put into the manual 'ON' position, as it should.
Many thanks and I will post an update in a few days.

Connect your wires as shown in the diagram. (Without blue to B)
