 Temp Control (80°F - 104°F / 26°C - 40°C)

The last measured water temperature is constantly displayed.

The water temperature displayed is current only when the 
pump has been running for at least 2 minutes.

On panels with a single “Temp” or “Set” button,

 to display 

the set temperature, press the button once. To change the set 
temperature, press the button a second time before the display 
stops flashing. Each press of the button will continue to either raise 
or lower the set temperature. If the opposite direction is desired, 
allow the display to revert to the current water temperature. Press 
the button to display the set temperature, and again to make the 
temperature change in the desired direction.

On panels with “Warm” and “Cool” buttons,

 to display the 

set temperature, press “Warm” or “Cool” once. To change the set 
temperature, press a temperature button again before the display 
stops flashing. Each press of “Warm” or “Cool” will adjust the 
set temperature.

After three seconds, the display will stop flashing and begin to 
display the current spa temperature.

 

Jets 1

Press “Jets 1” to turn pump 1 on or off, and to shift between low 
and high speeds (if equipped). The low-speed will turn off after 
4 hours. High-speed will turn off after 15 minutes. Low-speed 
may run automatically at times, during which it cannot be 
deactivated from the panel, but high-speed may be operated.

 

 

Jets 2/Jets 3/Blower (If equipped)

Press the corresponding button once to turn the device on or 
off. The device will turn off after 15 minutes. Pump 2 may be 
two-speed on some systems.

Some systems use this one button to control two devices. The first 
button press will activate one device. Press again to have both 
devices active. Press again to turn off the first device only. Press 
one more time to turn both devices off.

Initial Start-up

Your spa will enter Priming Mode (

) when it is energized. 

During Priming Mode, press “Jets” button(s) repeatedly and 
be sure all pumps are free of air. 

Priming Mode lasts less than 

5 minutes. Press “Temp” to exit. After Priming Mode, the spa 
will run in Standard Mode (see Mode section). Some panels may 
not have a “Temp” button. On these panels the “Set,” “Warm,” or 
“Cool” buttons are used.

Button shapes and labels may vary.

Balboa 500Z-Series Operation Guide

This document covers VS and GS systems 500Z through 521Z with Balboa Panels VL200 through VL406.

 

Light

Press “Light” to operate the spa light. Turns off after 4 hours. 

Mode

Depending on system configuration, mode changing may not be 
available and will be locked in Standard Mode.

Mode is changed by pressing “Temp,” then “Light”.

Standard Mode

 maintains set temperature. 

 will be displayed 

momentarily when you switch into Standard Mode.

Economy Mode

 heats the spa to the set temperature only during 

filter cycles. 

 will display when water temp is not current, and 

will alternate with water temp when the pump is running.

Sleep Mode 

heats the spa to within 20°F/10°C of the set 

temperature only during filter cycles. 

 will display when water 

temp is not current, and will alternate with water temp when the 
pump is running. 

Preset Filter Cycles

The first preset filter cycle begins 6 minutes after the spa is 
energized. The second preset filter cycle begins 12 hours later. 
Filter duration is programmable for 2, 4, 6, or 8 hours or for 
continuous filtration (indicated by 

). The default filter time is 

2 hours for non-circ systems and 4 hours for circ systems.

To program, press “Temp,” then “Jets 1.” Press “Temp” to adjust. 
Press “Jets 1” to exit programming.

For non-circ systems

, low-speed pump 1 and the ozone generator 

(if installed) run during filtration.

For 24 hour circulation systems

, the circ pump and the ozone 

generator (if installed) run 24 hours. In hot environments, the 
circ pump may turn off for 30 minute periods, except during 
filter cycles. 

For non-24 hour circulation systems,

 the circ pump and ozone 

generator (if installed) run during filtration (and may also run 
automatically at other times).

At the beginning of each filter cycle

 all other equipment will 

run briefly to purge the plumbing.

The pump responsible for heating and filtration (pump 1 low-speed 
on non-circ system, or the circ pump on circ systems) will be 
referred to simply as the pump.

In multi-button sequences, if the buttons are pressed too quickly in 
sequence, they may not register.
