Anyone have any thoughts on why my Geo system "short cycles" in the Spring and Fall when the outside temperatures are transitioning? By short cycling I mean the compressor comes on and runs for a very short time < 5 min and then shuts off. I doesn't happen all the time and the system seems to be running fine all winter. Its just when there is a warmish day but the temp drops in the evening or sometimes in the morning. The secondary loop temp (radiant) has dropped to ambient in most of these cases so a couple minute compressor run does nothing but wear the motor and start capacitor. I have an outdoor reset controller to throttle the water temp based on the outdoor temp. I'll be happy to give more specifics on the system if needed. I just was wondering if this implicates any obvious problems to knowledgeable pros. Thanks for any and all help!
