| Does anyone know what differential temperature setting is best to use for cost savings? Mine will go down to .5 deg F or up to 3 deg F and I am not sure which setting to use. If I have it set at 1.5 then the ac has to play catch up and the extra cooling kicks in. If I have it at .5 then it stays on most of the time. |

It means that if the thermostat differential temperature is set at 1 and your temp is set at 80, then your ac starts at 81 and shuts off at 79. If it is set at .5 then it starts at 80.5 and shuts off at 79.5. |

2 degrees is the normal setting on, I think all the
residential thermostats. This is what I have seen in the 23 years I did HVAC/R I wonder why you ask, if you think the unit has trouble recovering IN the comfort zone with 2 degrees dif. there is something wrong with the unit not the t stat; or you are a woman. When I went to the design engineering classes, "the only class one cannot satisfy is women " they teach this because of menopause I guess. no way to make them comfortable

the more i think about it are you fooling around with the heat anticipator on the thermostat? if so that is for the heat cycle not for the cooling No. It is the thermostat. The thermostat was set at 1.5 dif and the second stage cooling was kicking in to catch back up. My question was, does it matter if I put it on .5 or keep it on 1.5 as far as cost savings? I am about to put a lock box on the thermostat because someone insists on keeping the temp at 72 deg F and our electric bill is killing me. |

I don't know the answer,
1) what is the humidity of the house in the off cycle....important measurment 2) what is the off cycle time 3) when in operation what is the on time cycle 4) Did you increse the capicity of the unit like 3 ton to 5 ton 5) is the t-stat wired correctly 6) humidity Oh! that's #1 in many ways. it will be 74 degrees temprature and feel not right some say clammy but not comfortable hence setting to 72 or 70 7) thermostat lock box 8) sorry not sure
