I have a Lennox XP16 matched to a CBX27UH A/H. House has three zones. Two downstairs set to 75. Upstairs set to 79. Outside temp is around 90 with high humidity. The settemps are being maintained, however, during most of the day, the system is constantly running. It is very rare that the entire system shuts off during the day.
Question: Is this normal operation for a HP with multiple zones? Is it their function to just maintain the set temp?, or should the system cycle on/off?
Thanks for your assistance.
