2.7 Freeze Protection

When freeze protection is active, water is circulated through designated group's plumbing circuits in 5 minute
cycles. The water circulation lowers the chances of water freezing in those circuits.
Freeze protection will automatically activate when the air temperature falls below 37° F (3° C).
l
When the air temperature rises to 43° F (6° C), freeze protection will deactivate.
l
These set temperatures and cycle times can be adjusted as needed in settings. See "Adjusting Freeze Protection
l
Options" on the next page.
PLEASE NOTE:
Freeze protection is meant to be temporary. If freezing temperatures will continue for an
l
extended time frame, the pool equipment must be winterized.
The heat pump will not attempt to heat water in freezing conditions.
l
As a group cycles on and off, any devices contained within that group will also cycle on and
l
off. If this behavior is undesirable, the device can either be removed from the group or
manually deactivated.
