Jacuzzi J-280 User Manual

The spa control system has automatic functions that operate upon 
start-up and normal operation to protect the system. Upon power up, the 
readout displays the following information:

1.  Control panel displays current software 

release (3.56 or 5.56 depending on spa 

model) then;

2.  Control panel displays “888” and all 

indicator LEDs are lit, permitting visual 

inspection of all display segments and 

indicator lights for proper operation.

3.  After the initial start-up sequence 

ends, the actual water temperature is 

displayed. If water temperature at this 

time is less then the factory default temperature setting of 100°F 

(38°C) and the spa is set to either standard filtration/heating mode 

(Sections 11.1-11.2, page 28), the heater will turn on and run until the 

water temperature rises to the factory setting, then turn off. 

note: It is common for the heater to turn on after the spa is first filled 
because tap water is often very cold.

The spa’s thermostat provides optimum control of 
water temperature. The temperature set point (set 
temperature) can be adjusted from 65-104°F (18-40°C). 
To raise the set temperature, press the WARMER (

) 

button. To lower the set temperature, press the COOLER (

) button. 

note: The first press of either WARMER (

) or COOLER (

) button 

displays the set temperature.

The control panel JETS 1 button activates jets pump 1. 
The first press activates low speed, the second press 
activates high speed, and the third press shuts jets pump 
1 off. The JETS 2 button activates jets pump 2. The 
first press activates high speed, the second press turns jets pump 2 off. 
When manually activated, either pump will automatically turn off after 20 
minutes.

The light button activates the foot well light in the spa 
when pressed. Pressing the button turns the foot well 
light off. When manually activated, the foot well light will 
automatically turn off after one hour.
