I never use any humidity control, except the normal air conditioning, which is always set at 79 degrees, day and night. Those are the facts.

OK, Everything sounds good but it's still strange to see how the humidity can stay so low without the A/C running a lot in the summer. Maybe some other's can comment.

But you are correct, the better the thermostat keeps the temperature at the set point, the more it's running accelerating wear on the compressor.

A thermostat's swing setting, also known as temperature differential or maintenance band, determines how much the temperature fluctuates above or below the setpoint before the heating or cooling system engages. This setting affects how often your HVAC system cycles on and off. A smaller swing setting results in more frequent but shorter cycles, while a larger swing setting leads to fewer but longer cycles.

Thanks - found the automatic staging needs to be changed to manual to set the swing.

From there, you can adjust the heat/cool differential temperature.

The default swing value is ±0.50°F, changed it to ±1.5°F.

Maybe the poured in place homes have lower air infiltration?

Maintaining your relative humidity level between 39 and 47% is somewhat out of range for residential a/c systems in central Florida. Probably need to recalibrate your hygrometers. I needed to do so every six months or so when I felt the need to track RH for my satisfaction. Now I can read it on my programmable t-stat app, but I’m not convinced that it’s accurate.
I also keep my house at 79 degrees F during the day and 77 at night, but my RH is between 58 and 62% when I disable the humidity control feature.

No they are factory, I wrote on capacitor so I knew what size to to buy have extra one to fit like factory one.

I have same CYV size, run time same, humidity around same. Just got my electric bill yesterday 144. dollars. Temp setting 78 degrees.

I actually have 4 hygrometers spread around the house. One is part of a weather station that tracks the outdoor and indoor conditions. Two of them I have had for 8 years that are strictly measuring indoor conditions. Recently, I added another indoor unit. I am very certain that my humidity measurements are accurate, as they have never deviated more than about 2 percent from the others. If you are measuring indoor humidity, I recommend using at least two hygrometers because they are not as accurate as a thermometer.

I'm house sitting and last Saturday's storm affected the thermostat for the a/c unit. it's 65 degrees in the house....the thermostat is set @ 85!...Munn's will not come out because I'm not listed on the homeowners account...any suggestions please?....

I would try turning off the HVAC breaker, wait a minute, and turn it back on to see if the system resets.

The homeowner needs to get someone there if that doesn't work.

The homeowner should be able to authorize Munn's to repair the system. They may need to provide a credit card number.
