Control System Features

High Temperature Limit Protection

The high temperature limit 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 temperature 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.

Ozone Generator Operation

The ozone generator (if equipped) will operate during the filter cycles only.

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.

120 VAC 15/20 Amp Setting (Heater mode selector)

The spa when installed 120 VAC 15 Amp will run the heater on low speed jet only. If equipped with a

Blower the spa will come equipped with a 20 Amp GFCI to handle the additional amps that the blower

requires.

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

If the spa is converted to 240 VAC 50 Amp, then the power of the heater will change from 1kw to 4kw and

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 change from 1kw to 4kw, but will not operate with the high speed

jets. This conversion and all wiring should be done by a licenced electrician.
