ISSUE
The heat pump has sensed the air temperature has dropped below 37° F (0° C). This is the default
setpoint before the heat pump begins to circulate water to groups marked as needing freeze protection.
The heat pump will not heat water in these conditions. (See "
Freeze Protection
" on page 69 for more
information.)
NOTICE
Failure to heed the following may result in damage to equipment.
l
Freeze protection is meant to be temporary. If freezing temperatures will continue for an extended time
frame, the pool equipment
must
be winterized.
PLEASE NOTE:
This protection is only available for heat pumps that directly control a circulation
pump.
