7.2.4 Setting the Freeze Temperature
The pump must be controlled by the heater's
internal time clock for the freeze protection to operate.
The LJ controller will protect your pool and spa
equipment from damage due to freezing for short
periods of time. Once the 'FREEZE TEMPERA-
TURE' is set and the heater is in the 'OFF' mode, the
pump will automatically start when the water tempera-
ture drops to the 'FREEZE TEMPERATURE'. The
pump will shut off when the water has warmed to 2°
above the 'FREEZE TEMPERATURE'.
NOTE: The temperature set range for the
'FREEZE TEMPERATURE' is 34°F (1°C) to 42°F
(5°C). If an attempt is made to set a temperature
outside of this range, the words 'INVALID COM-
MAND' will appear on the left side of the display.
