roundcake4Quality Hot Tub / Spa Controllers

People always say “you get what you pay for” that’s not always true. Some companies sell their products at the highest price possible, and cut cost by any means necessarily, sacrificing quality, service and anything else they think you wont notice until after you purchased their product. At Trinity Electronic Labs we believe in honoring God in all we do, that means not only do we provide the hands down best customer service and support, but we also make the highest quality lowest cost Spa / Hot Tub Controller available.


  • Quality Starts with our Hot Tub / Spa Circuit Board …

    Circuit Board Inspection

    Our Spa Circuit Boards / Hot Tub Circuit Boards are tested before they get assembled. They are then populated with the highest quality name brand independently certified components and inspected. The Spa Circuit Boards / Hot Tub Circuit Boards are wave soldered and then inspected again. Each control board is then cleaned and once again inspected. After installing the connectors and fuses each one of our Spa Circuit Boards / Hot Tub Circuit Boards are inspected again. Each Spa Circuit Boards / Hot Tub Circuit Boards is placed on a simulator and  tested again. After passing certain components and connectors are glued to prevent damage from handling by us or by the installer. Each Spa Circuit Boards / Hot Tub Circuit Boards is then sprayed with a protective coating to ensure a long life in a hostile environment. Finally the control boards are inspected under an ultra-violet light and are then ready to be installed in a new spa pack.
  • The Quality Continues with our Digital Top Side Controls

Top Side Control Programming and Testing

Our Top Side Controls are made with the finest care and quality products. Each board is inspected under a microscope for quality. The boards are then installed into its enclosure, after-which each Top Side Control is programmed and tested twice. After passing both test the internal parts are coated and then the Top Side Control is sealed, both to protect it during it long life in a very hostile environment.  All this is done to ensure that when you receive your Hot Tub Controller it works right from the beginning and continues to work for you for years to come.    
  • Final Assembly of  Your New Hot Tub Controller

Full Test on a Simulator

Each Hot Tub Controller is assembled by hand by an experienced technician. After assembling the Control System the technician installs the Spa Pack on to one of two simulators. By connecting the Spa Controller to the simulator we ensure that everything works. Wires are connected to the terminal block from a ground fault protected circuit breaker, so we know for a fact that there are no issues with them when you go to install your Hot Tub Controller. Likewise, a circulation pump, pump 1, pump 2, a blower and a light are connected to the Hot Tub Controller. So that once again we know for a fact that everything works and the connections are good. After the Spa Controller is connected to the electric and all the equipment is connected to it, the plumbing connections are made. We have two separate simulators one connects the Control System to a standard 2″ plumbing using a 2 speed pump 1, and the other connects the Spa Pack to a circulation pump using our low flow kit with 3/4 ” plumbing. This is done once again so we know for a fact that whether you use a standard 2 speed pump 1 or a circulation pump with our low flow kit the system you have works. Finally now that the electric and the plumbing connections are complete the unit is turned on and ran through the start-up sequence. Since the Hot Tub Controller is connected to a GFIC, we know it does not have any electrical issues. Because it is connected to the plumbing we know it doesn’t leak. Since it has all the possible equipment connected to it we know that no matter what you connect to the Spa Pack IT WORKS!  
  • Final Testing and Inspection of Our Complete Spa Controller

Dielectric / Withstand Voltage  & Continuity Testing

Finally before our Hot Tub Controllers are packed they are put to a final round of testing. In this test the Spa Controller is subjected to 1500 volts to ensure that the hot tub circuit board can withstand voltages  six  to twelve times that which it will be connected to. All wire connections are checked again to make sure they are tight, and all screws are checked again to ensure they are secure. The Hot Tub Controller is then cleaned and inspected one final time before packing. One final check of the assembly check list is made before the Spa Pack is sealed in it’s box and ready to ship. We do all of this so we know and you can count on the fact that your new Spa Pack works! If you have trouble with it working when you get it, you can focus your attention to the other equipment or the installation instructions as the reason NOT that the new Spa Pack is defective.

Frequently Asked Questions (FAQ)

Technical Details

I want to add a blower on 2-speed primary and 1 speed secondary. Will this support a 220 or 110 volt blower? What blower would you recommend with this unit?

The board is configurable by moving jumpers around. Any blower 120V or 240V will work. You do need to maintain the same horse power. Millennium blowers self adjust, so we would recommend them.

How many amps does the spa pack draw at 120V voltage?

Running on 120 volts, the heater will use 12 amps. Check the amperage on your pump for low speed. It should be 1-3 amps. The spa should be connected to a 20 amp dedicated line with a GFIC. You can open up the unit and set all the output and input amp draw voltages depending on how many things would be running

Does the ozone only run with pump 1 or only in filtering mode?

It runs with pump 1 low, whether or not you actually have a pump 1.

How many KW is the heater?

The heating element is 5.5 KW.

Can I run a 120V, 1000GPH pool pump from the 120v pump controller? What is the maximum current draw for a single speed pump port?

The max is 240V. We recommend buying a 4-pin plug for the controller.

Does the Apollo 11 spa pack included a motor. If so, what is the horsepower?

This is the control and heat unit only. It runs motors, but does not include any motors or pumps.

Are the white wires in the controller the hot wire or the neutral wire?

The white wire from the breaker box goes to the neutral inside the controller.

What are the dimensions of the top controller?

The topside control panels is 7″ x 3″.

What size plumbing does this have?

The Apollo 11 spa pack fits directly to a 2″ PVC pipe. Adapters are also available from hardware stores.

Will It Work With...?

I have a Cal spa, one motor with a two seep pump. One for circulation, and one for jets. The other for different jets. Will the Apollo 11 PAC work?

Yes, it’s designed to work in this situation.

I have a hydro-Quip with a 2 speed pump which runs on low speed to circulate when heating/filtering. There is no separate circulation pump, will the Apollo 11 work?

Yes, it will. Simply plug that pump into the pump 1 receptacle.

I own an old Apollo spa with an M class control unit. Is this a direct replacement?

The Apollo 11 spa pack is a matched set, replacing the controller and control panel entirely. It also includes the heating element assembly as a drop and go replacement unit. Install, reconnect the blower, pumps, and control panel. Our unit becomes the new brain for your hot tub. The control fit will fit above the heater.

Will this work on a Sundance 780 Series?

Yes, it will work.

Will the Apollo 11 spa pack work with two single speed 240v pumps? What about just 1 two-speed pump?

Yes, it will work with the two pumps and one.

Will this controller operate 2 two-speed pumps and a blower, plus an ozonator and LED lights?

No, the Apollo 11 will not operate 2 two-speed pumps. Only 1 2-speed pump plus a second single speed pump is possible. The Apollo 11 also connects with ozonators, blowers, and LED lights. For this full functionality, be sure to pick up the Apollo 11 V Pack.

Will this work for a concrete hot tub?

Yes, our unit will work with any spa that has the appropriate electrical and plumbing connections.

Will the Apollo 11 spa pack work with a Polynesian Spa, and can I reuse old components?

Yes! It will work on a Polynesian Spa, but you may need to change or adapt some of the cords. We can specifically help out by knowing more about your unit.

What is the upper control unit plug that comes with the Apollo 11 spa pack?
It is unique to the Apollo 11. It comes with the cable attached and plugs into the control box.

Troubleshooting & How To

How do I restart the unit after a power failure?

Reset the breaker your hot tub is tapping into. If your power up is still not working, please give us a call.

My spa is always at 108F despite the temperature setting at less than 100F. Why is this happening? My unit is reading 5-8 degrees higher than actual temperature. What is going on?

The most likely scenario is pump 1 hi and low are reversed causing filtering on high instead of low. This will generate more heat. 
The temperature reads closer to the heating element than the actual tub, the water flowing out of the jets.
In some cases, mechanical elements are enclosed in a waterproof “dock box” above ground. When the sun warms the dock box, you may get false temperature readings.
Please call and we can diagnose this further.

After turning up the heat, the unit goes into default mode. What's going on?

Check your relays. Your wiring could be wrongly installed. If you have trouble, please call us and we’ll be happy to walk you through the troubleshooting process.

The unit shuts down at stage 1, but when pressing on the unit casing, the spa pack turns back on. What's going on?

Make sure to give the unit plenty of time to cycle. You could also test your grounding wires and make sure they are tight at the motors and casing.
