Control System Features

High Temperature Limit Protection

The high temperature protection will disable all relays when the spa water temperature is equal to or

greater than 120ºF(48ºC). This condition will require manual reset by pushing the buttons simulta-

neously, or by turning the power off and then back on. The high limit protection cannot be reset until the

spa water temperature drops below 117ºF(47ºC). The high limit protection disables all relays when the

heater enclosure temperature reaches 125ºF(51ºC) or greater. The heater high limit cannot be reset until

the heater enclosure temperature drops below 123ºF(50ºC). This condition requires a manual reset by

pushing the buttons simultaneously, or by turning the power off and then back on.

Water Clean-out Cycle

To keep the water from becoming stagnant in the plumbing lines and in the spa, the “Jets1”, “Jets 2” (if

equipped) and the blower (if equipped) will automatically turn on for 5 minutes of operation if the jet

pump(s) or blower has not been energized in any 48 hour period.

Ozone Generator Operation

The ozonator generator (if equipped) will operate with the circulation pump except when the high speed

jets are in operation or in an overheat condition.

Temperature Set-Point Lockout (Temperature lock selector)

The temperature set-point lockout feature prevents unauthorized temperature adjustment of your spa

water. The default factory setting of the set-point lockout is unlocked. To lock your temperature set-point,

follow these instructions: Pressing and holding the buttons, then press the button. The light is

now on and the thermostat is now locked. You can press again and just the light will go off. To unlock

the temperature set-point, repeat this same procedure.

240 VAC 30/50 Amp Setting (Heater Mode Selector)

When the spa is installed 240 VAC 50 Amp, then the power of the heater will operate with the high

speed jets. The spa also has a 240 VAC 30 Amp configuration available. In the 240 VAC 30 Amp

setting the heater will not operate with either of the jet pumps running.
