Has anyone ever somehow wired a system so the heat pump can only turn on when there is a Heat/Cool call? I've noticed my heat pump will kick in sometimes after long periods of no use and run much shorter than normal. What I found was during the last call, the buffer tank was within a degree or two of the temp limit and the zone was satisfied. Not that its a huge deal, but wouldn't it make more sense to only allow the heat pump to run if there's been a call for heat/cool? Once there's been a call the heat pump would then run until the opposite set point is hit.
