I think that's it... I forgot to install the 2 pin jumper between terminal block positions 4 and 5. Unfortunately I had to order a new one since my wife already threw the leftover parts out. We'll see if that fixes it when it arrives in a few days. Thanks, Ben

I have a 2001 Hot Spring Sovereign. My heat wasn't working, so I just replaced the heater relay board with the new 77119 part for the IQ2020. Now I have heat and circulation, but the jets stopped working (wavemaster 7000 ver3). They were working previously, but do not anymore. The jet icon lights up on the control head, but no jets. Any ideas? What could I have done in replacing the heater relay board that affected the jets? Thanks, Ben
