ML240 Quick Reference Guide

Initial Start-up

When your spa is first actuated, it will go into Priming

mode (after displaying some configuration information).

Please see the M-7 Installation Instruction Manual for

complete instructions on Power-up and Pump Priming.

The Priming mode will last for up to 4 minutes and

then the spa will begin to heat and maintain the water

temperature in the Standard mode. You can exit Priming

mode early by pressing “Temp”.

Temp

Press the “Temp” button once to display the set

temperature. To change the set temperature, press the pad

a second time before the LCD stops flashing. Each press of

the “Temp” button will continue to either raise or lower the

set temperature.

If the opposite direction is desired, release the pad and let

the display revert to the current water temperature. Press

the pad to display the set temperature, and again to make

the temperature change in the desired direction.

After three seconds, the LCD will automatically display the

last measured spa temperature.

Jets

Press the “Jets” button once to turn pump 1 on or off, and

to shift between low and high speeds if equipped. If left

running, the pump will turn off after a timeout period. The

pump 1 low speed timeout on some systems may be as

long as 4 hours.

On non-circ systems, the low speed of pump 1 runs

when the blower or any other pump is on. It may also

activate for at least 1 minute every 30 minutes to detect

the spa temperature (polling) and then to heat to the set

temperature if needed, depending upon mode. When the

low speed turns on automatically, it cannot be deactivated

from the panel; however, the high speed may be started.

The Balboa EL/GL Series - Mach 3 ML240 Quick Reference Guide describes a spa control system designed for ease of use and maintenance. This system allows users to manage various spa functions, including temperature, jets, and operational modes, through a user-friendly control panel.

Initial Setup and Operation

Upon initial activation, the spa enters a "Priming mode" to prepare the system for operation. This mode typically lasts up to 4 minutes, during which the spa displays configuration information. Users can exit Priming mode early by pressing the "Temp" button. After priming, the spa automatically transitions to "Standard mode," where it begins heating and maintaining the water at the set temperature. For detailed instructions on power-up and pump priming, users should consult the M-7 Installation Instruction Manual.

Temperature Control

The "Temp" button is central to managing the spa's temperature. Pressing it once displays the current set temperature. To adjust the temperature, the button must be pressed a second time while the display is still flashing. Each subsequent press of the "Temp" button will either increase or decrease the set temperature. If the desired adjustment direction is opposite to the current sequence, the user should release the button, allow the display to revert to the current water temperature, and then press the button again to initiate temperature change in the new direction. After three seconds of inactivity, the LCD automatically reverts to displaying the last measured spa temperature.

Jet Control

The "Jets" button controls the spa's pump 1. Pressing it once turns pump 1 on or off. If the system is equipped with multiple speeds, pressing the button also allows users to switch between low and high speeds. To prevent continuous operation, the pump will automatically turn off after a predetermined timeout period. On some systems, the low speed of pump 1 may run for as long as 4 hours before timing out.

For non-circulating systems, the low speed of pump 1 activates automatically when the blower or any other pump is in operation. It may also engage for at least 1 minute every 30 minutes to "poll" the spa temperature, and then to heat the water to the set temperature if necessary, depending on the current operational mode. When the low speed activates automatically, it cannot be manually deactivated from the control panel; however, the high speed can still be initiated.

Operational Modes

The ML240 system offers several operational modes to optimize energy consumption and spa usage:

Standard Mode: This is the default mode where the spa maintains the desired temperature continuously. The displayed spa temperature is current only if the pump has been running for at least 1 minute. When switching to Standard Mode, "5td" will briefly appear on the display.
Economy Mode: In this mode, the spa heats the water to the set temperature only during filter cycles. "Ecn" will appear as a solid indicator when the temperature is not current and will alternate with the temperature when it is current.
Standard-In-Economy Mode ("5E"): This temporary mode is activated by pressing "Jets" while in Economy mode. It operates identically to Standard Mode but automatically reverts to Economy Mode after 1 hour. Users can manually revert to Economy Mode immediately by pressing "Temp" followed by "Light."
Sleep Mode: This mode is designed for maximum energy savings, heating the spa to within 20°F (11°C) of the set temperature only during filter cycles. "SLP" will be displayed until the mode is changed.

To switch between these modes, a specific button combination is required: press "Temp" followed by "Light" to enter mode programming. Then, press "Temp" to cycle through the available modes (the LCD will flash until confirmed). Finally, press "Light" to confirm the desired mode selection.

Standby Mode

The "Standby Mode" is a temporary state that turns off all spa functions, which is particularly useful for maintenance tasks like changing a filter. To activate Standby Mode, press "Temp" followed by "Aux," "Jets 2," or "Blower." Pressing any button will exit Standby Mode. On some systems, the "Jets" button may control the pump in Standby Mode (referred to as "Drain Mode"). In such cases, pressing any other button will exit Standby Mode. The system will automatically revert to its previous operational mode after 1 hour in Standby.

Locking Features

The ML240 panel offers locking features, but their availability depends on whether the panel is configured as the main control panel or as a remote/additional panel.

Main Panel: If the ML240 panel is used as the main control panel, locking features will not be available directly on this panel.
Remote/Additional Panel: If the ML240 panel is used as a remote or additional panel, it will lock automatically when the main panel is locked. To unlock the remote panel, the main panel must first be unlocked. Similarly, the set temperature can be locked and unlocked by the main panel. When the set temperature is locked, it cannot be changed from either the main or the remote panel.

Maintenance and Additional Information

For complete instructions on power-up and pump priming, users should refer to the M-7 Installation Instruction Manual. For additional details and features available with the ML240 panel and EL/GL Series system, users are advised to consult their comprehensive User Guide. The device is ISO 9001 Certified, ensuring quality and reliability.
