Ready-in-Rest Mode
READY/REST appears in the display if the spa is in Rest Mode and Jet 1
is pressed. When the spa is being used, it will heat to set temperature.
While Pump 1 High can be turned on and off, Pump 1 Low will run until
set temperature is reached, or 1 hour has passed. After 1 hour, the system
will revert to Rest Mode. This mode can also be reset by entering the Mode
Menu and changing the Mode.
Freeze Protection
If you live in an area that experiences extreme freezing weather, you need to know how to how to set your
spa to prevent freeze damage. Some spa owners choose to drain and winterize their spas, but others prefer
to keep it filled and operating. If you don't want to drain your spa, you can continue to run it safely through
the winter, providing you program it correctly.
When you expect the temperature to approach freezing, always keep the spa in READY Mode. As long as the
spa is in READY Mode, it will regularly check the water temperature (known as "polling") and circulate water
every 1/2 hour.
When the sensors within the heater detect water temperature has dropped to 42°F (5.5°C), then the pumps
and the blower automatically activate to provide freeze protection. The pumps and blower will run either
continuously or periodically depending on conditions.

"heater pump."

The heater pump can be either a 2-Speed Pump 1 or a circulation pump. If the
heater pump is a 2-Speed Pump 1, READY Mode will circulate water every 1/2
hour, using Pump 1 Low, in order to maintain a constant water temperature,
