I have a Tecmark command center model CC4-120-10-X-00 that worked fine for many years. However, the water only heats to 70 degrees now and I think its the electronic temp sensor. I disassembled the control and reseated the two leads to the circuit board. Now the water heats to 90.

Can I use a Brett or Balboa temp sensor assembly w/o problems on this old board? I can't find a parts number on the temp sensor wire currently plugged into this board.

There are no adjustment screws on the circuit board itself so I can't adjust that... Open to suggestions here, seems a shame to buy a completely new $120+ assembly just cause the sensor wire got water logged or something...

Thanks,

In case anyone else needs to replace the sensor bulb on their Tecmark, its pretty cheap to just replace the entire assembly if you purchase a new one from The spa depot http://www.spadepot.com
