Call Wolfers... They are the best around.
Try by removing the wall termostat and look if the heatpump stops, if IT does then likely IT is a detective termostat but of IT does not stop a stuck electrical switch might be the issue and you need a Pro for help. I am a Wolfers tech. Thanks
We have had Wolfers do work for us twice and they technicians are p professional and reliable. They came highly recommended. And I agree.. good luck!
