Main Menus

Navigation
Navigating the entire menu structure is done with 2 or 3 buttons on the control panel.

BALBOA TP500 Control Panels - NavigationSome panels have separate WARM (Up) and COOL (Down) buttons, while others have a single Temperature button. In the navigation diagrams Temperature buttons are indicated by a single button icon.
Panels that have two Temperature buttons (Warm and Cool) can use both of them to simplify navigation and programming where a single Temperature icon is shown.
The MENU/SELECT Button is used to choose the various menus and navigate each section.
Typical use of the Temperature button(s) allows changing the Set Temperature while the numbers are flashing in the LCD. the menus can be exited with certain button presses. Simply waiting for a few seconds will return the panel operation to normal.

Power-up Screens
Each time the System powers up, a series of numbers is displayed.
After the startup sequence of numbers, the system will enter Priming Mode (See Page 3).

Spa Behavior

Pumps
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 time-out period. On non-circ systems, the low-speed of pump 1 runs when the blower or any other pump is on. If the spa is in Ready Mode (See page 6), Pump 1 low may also activate once in a while for at least 1 minute to detect the spa temperature (polling) and then to heat to the set temperature if needed. When the low-speed turns on automatically, it cannot be deactivated from the panel, however the high speed may be started.
Circulation Pump Modes
If the system is equipped with a circ pump, it will be configured to work in one of three different ways: 1, The circ pump operates continuously (24 hours) with the exception of turning off for 30 minutes at a time when the water temperature reaches 3°F (1.5°C) above the set temperature (most likely to happen in very hot climates). 2, The circ pump stays on continuously, regardless of water temperature. 3, A programmable circ pump will come on when the system is checking temperature (polling), during filter cycles, during freeze conditions, or when another pump or blower is on. The specific Circulation Mode that is used has been determined by the Manufacturer and cannot be changed in the field.

Temperature and Temp Range

Adjusting the Set Temperature
When using a panel with Up and Down buttons (Temperature buttons), pressing Up or Down will cause the temperature to flash. Pressing a temperature button again will adjust the set temperature in the direction indicated on the button. When the LCD stops flashing, the spa will heat to the new set temperature when required.
If the panel has a single temperature button, pressing the button will cause the temperature to flash. Pressing the button again will cause the temperature to change in one direction (e.g. UP). After allowing the display to stop flashing, pressing the Temperature Button will cause the temperature to flash and the next press will change the temperature in the opposite direction (e.g. DOWN).
Press-and-Hold
If a Temperature button is pressed and held when the temperature is flashing, the temperature will continue to change until the button is released. If only one temperature button is available and the limit of the Temperature Range is reached when the button is being held, the progression will reverse direction.

Dual Temperature Ranges
This system incorporates two temperature range settings with independent set temperatures. The High Range designated in the display by a thermometer and an “up” arrow, and the Low Range designated in the display by a thermometer and “down” arrow.
These ranges can be used for various reasons, with a common use being a “ready to use” setting vs. a “vacation” setting.
The Ranges are chosen using the menu structure below. Each range maintains its own set temperature as programmed by the user. This way, when a range is chosen, the spa will heat to the set temperature associated with that range.
For example:
High Range might be set between 80°F and 104°F.
Low Range might be set between 50°F and 99°F.
More specific Temp Ranges may be determined by the Manufacturer.
Freeze Protection is active in either range.
See Ready and Rest on Page 6 for additional heating control information.

BALBOA TP500 Control Panels - High-Range

Mode – Ready and Rest

In order for the spa to heat, a pump needs to circulate water through the heater. The pump that performs this function is known as the “primary pump.”
The primary pump can be either a 2-Speed Pump 1 or a circulation pump.
If the primary pump is a 2-Speed Pump 1, Ready Mode (indicated by R ) will circulate water periodically, using Pump 1 Low, in order to maintain a constant water temperature, heat as needed, and refresh the temperature display. This is known as “polling.”
Rest Mode (indicated by ) will only allow heating during programmed filter cycles. Since polling does not occur, the temperature display may not show a current temperature until the primary pump has been running for a minute or two.
Circulation Mode (See Page 4, under Pumps, for other circulation modes)
If the spa is configured for 24HR circulation, the primary pump generally runs continuously. Since the primary pump is always running, the spa will maintain set temperature and heat as needed in Ready Mode, without polling.
In Rest Mode, the spa will only heat to set temperature during programmed filter times, even though the water is being filtered constantly when in Circulation Mode.

The Main Screen will display normally during Filter Cycles or when the spa is in use.
If the primary pump has been off for an hour or more, when any function button, EXCEPT Light, is pressed on the panel, the pump used in conjuncton with the heater will run so that temperature can be sensed and displayed.

Ready-in-Rest Mode

R   appears in the display if the spa is in Rest Mode and “Jets” is pressed. It is assumed that the spa is being used and will heat to set temperature. The primary pump will run until set temperature is reached, or 1 hour has passed. After 1 hour, the System will revert to Rest Mode. This mode can also be reset by entering the Mode Menu and changing the Mode.

Show and Set Time-of-Day

Be sure to set the Time-of-Day
Setting the time-of-day can be important for determining filtration times and other background features.
When in the TIME menu, SET TIME will flash on the display if no time-of-day is set in the memory.
24-hour time display can be set under the PREF menu. (See Page 12)

Menu Note:
This note refers to systems that do not keep track of Time-of-Day when powered down.
If power is interrupted to such a system, Time-of-Day is not stored. The system will still operate and all other user settings will be stored. If filter cycles are required to run at a particular time of day, resetting the clock will return the filter times to the actual programmed periods.
When such a system starts up, it defaults to 12:00 Noon, so another way to get filter times back to normal is to start up the spa at noon on any given day. SET TIME will still flash in the TIME Menu until the time is actually set, but since the spa started at noon, the filter cycles will run as programmed.

Adjusting Filtration

Main Filtration
Filter cycles are set using a start time and a duration. Start time is indicated by an “A” or “P” in the bottom right corner of the display. Duration has no “A” or “P” indication. Each setting can be adjusted in 15-minute increments. The panel calculates the end time and displays it automatically.

Filter Cycle 2 – Optional Filtration
Filter Cycle 2 is OFF by default.
It is possible to overlap Filter Cycle 1 and Filter Cycle 2, which will shorten overall filtration by the overlap amount.
Purge Cycles
In order to maintain sanitary conditions, secondary Pumps and/ or a Blower will purge water from their respective plumbing by running briefly at the beginning of each filter cycle.
If Filter Cycle 1 is set for 24 hours, enabling Filter Cycle 2 will initiate a purge when Filter Cycle 2 is programmed to begin.

General Messages

Water Temperature is Unknown
After the pump has been running for 1 minute, the temperature will be displayed.
BALBOA TP500 Control Panels - Unknown Too Cold – Freeze Protection
A potential freeze condition has been detected, or the Aux Freeze Switch has closed, and all pumps and blower are activated, either one at a time, or all at once, depending on how your system was built. All pumps and blower are ON for at least 4 minutes after the potential freeze condition has ended, or when the aux freeze switch opens.
In some cases, pumps may turn on and off and the heater may operate during Freeze Protection.
This is an operational message, not an error indication.
BALBOA TP500 Control Panels - Hot Water is too Hot (OHS) – MO29
One of the water temp sensors has detected spa water temp 110°F (43.3°C) and spa functions are disabled. System will auto reset when the spa water temp is below 108°F (42.2°C). Check for extended pump operation or high ambient temp.
