Description
This OEM replacement IQ 2020 control board (motherboard) is for all IQ 2020 Control Boxes (77271) found on all 2001-2009.5 Hot Spring, Tiger River and Limelight spa models. It is used on domestic 60hz model spas only.
Note: This IQ 2020 control board (motherboard) does not include the secondary heater relay board or plastic encasement. This is the main circuit board (mother board) only.
Tech Tip: This IQ 2020 control board does not have thermistor ports on the right side of the board like the first generation 2001-2002 motherboards. The control thermistor and hi-limit thermistor connect directly onto this motherboard at the top edge. If your current (2001-2002) IQ2020 control box has thermistor ports on the right side exterior of the control box, then you will need different thermistors 78969 hi-limit thermistor and 78970 control thermistor.
Note#2: Lastly, this replacement motherboard does not come with a Pressure Switch Bypass Jumper item 72768. Something has to be plugged into the P34 Port, labeled Pressure Switch on this board in order for the spa to start heating. Either your existing heater has a gray cable that plugs into this port or your existing board has this jumper installed so you can remove it and install it on this new board.

Fit my 2005 sumatran tiger river spa. Was very easy to put in, i put it in all by myself with no prior experience.

Got the parts and good instructions and once I swapped the mother board out the spa started working again

This circuit board is the latest updated version and fit my hot tub perfectly. Backyardplus also had the best price anywhere.

Shipments are always prompt and accurate. I’ve been restoring a 2001 Hot Springs Jetsetter that my wife found for free. Backyardplus has always had the parts I needed as well as sound knowledgeable advice. (Everyone I sopke with was friendly and patient and never demeaning if I didn’t understand their answer). So 2 weeks later after rebuilding the jet pump and motor, replacing the main control board, the control module, the moto massage and a few other minor parts it’s woring like a new spa. Thanks

I had the pleasure of speaking with Craig from tech support, I bought this tub from a dealer used supposedly warranteed, got hooked it up and it was not operation, see the heater he installed in this application dId not have a pressure switch and the bourd was suppose to have a jumper, so when the heater came on the way he the dealer had it, would supply 220 volts right to the bourd, Craig found this error and sold me the parts for a complete repair thank you

I inherited an older hottub and backyard plus helped me navigate and learn quickly on how to diagnose and repair her quickly.

Man, I was sweating bullets. Afraid that there would be more issues.
This board was a perfect replacement. The guide it came with was a great guide. I even had a little issue with my pump not having two speeds and support walked me through the additional jumper changes I needed to make.
Great staff.

Thanks for the help troubleshooting. Oscar’s suggestion to hook the jet pump up to the circulation pump connectors on the mother board revealed that the jet pump was still operating. A mother board is way cheaper than a pump. Thanks again.
