sensors

One thing, start with cleaning wire contacts at sensor and make sure there is no water inside sensor, we find that. Then tighten all down and recheck. Tim

Make sure the sensor is disconnected from the 260 when you test...

reset

Try actually turning off the power to the control, wait 15 secs and then power back up. This may let the control reset itself if the sensor is good.

Attached is the values you should see with your meter. If good, when you re-attached, you will need to power down the control as mentioned above to reset.

Good luck
