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.

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.

Does this spa pack come with the pump and blower cords that plug into the side of the unit?

We do offer them, but they are sold separately.

Does this spa pack include the control panel?

Yes, we package the Apollo 11 spa pack to make it as easy as possible to repair your hot tub.

For my leisure garden spa uses a different plug type than the one in the photo. Are there converter cords available?

Yes, we do sell a cord adapter kit. The system only comes with the adapter for the light.

Does this spa pack include the cables for connecting the pack to the top side controller?

Yes. We include a 5″ cord and new heater “O” rings/gasket.

Does the Apollo 11 spa pack come with instructions & wiring diagrams?

Yes, the pack comes with instructions and wire diagram. Our website here also provides videos, and downloads to make the installation as easily as possible.

Does this spa pack come with a new pressure switch?

No. Our spa pack does not use pressure switches so the Apollo 11 will make your old ones obsolete.

Does the spa pack include wires that go to the electric panel, pumps, or blowers?

No, you can get the electric panel wires and GFIC breaker from Home Depot or Lowes. Pump and blower cords can be found on our store or Amazon.

Does this unit pump water into the spa as well as heat?

It does not pump but connects to your spa pump. It does come with a heating element.

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.

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.
