I have CT3200 and I notice that the AC compressor only runs for 8 minutes then shuts off. For better efficiency the compressor should run longer. Is there any way to increase the length of the ON cycle for the AC?

I already have the CT3200 set for a high efficiency (>90%) furnace.

The A/cight run short times if it is oversized but as long as it is removing enough moisture that is all that counts.

Here is your manual if you want to read it to see if the A/C is adjustable.
