SYMPTOM RULE OUT RESOLUTION
Water not
retaining heat
STEP 8:
If heating a spa, turn off water jets to allow for quicker
heating times. For pools, turn off water effects, such as
slides, waterfalls, or fountains to allow water to retain
heat more efficiently. Use of a liquid pool blanket
product, such as “Heatsavr
TM ”, can also compensate for
excessive heat loss.
STEP 9:
Call heat pump installer or AquaCal AutoPilot Customer
Support for further assistance.
Heat Pump Tripping Breaker
Weak breaker
STEP 1:
If breakers do not trip immediately, the issue is most
likely a weak breaker. Have an electrician confirm
breakers are in good condition and properly sized for
heat pump.

pump power
sequence
STEP 2:
Multiple heat pumps installed at the same site require
special automatic sequencing controllers to avoid
excessive power drops at start-up. Call heat pump
installer or AquaCal AutoPilot Customer Support for
further assistance on this type of equipment. See
“Automatic Sequencing Controller” in “Available
Accessories
” on page 35 for more information.

rare. Compressor failure must be determined before
replacement is considered. Call heat pump installer
or AquaCal AutoPilot Customer Support for further
assistance on this type of repair.
