Weak breaker
likely a weak breaker. Have an electrician confirm

Incorrect heat
excessive power drops at start-up. Call heat pump
pump power
installer or AquaCal AutoPilot Customer Support for
sequence
further assistance on this type of equipment. See
"Automatic Sequencing Controller" in "Available

temperature, then the heat pump is moving heat out of
the water.
