The Outdoor Temperature Sensor created a fault about 13:45 on the 29th of January causing a lot of inaccurate readings through out the Geothermal System. The problem was not noticed until about 11:30 on the 31st of January. The fault has knocked out most of the One Wire sensors. I have gotten most of the Ground Temperature Sensors back on-line. The 11 Foot sensor is still out as are the Outdoor Temperature Sensor, all other interior temperature sensors and the Thermostat output monitor. The Runtime monitors and the Electric consumption monitors are still operational. I am hoping to at least have the rest of the sensors on-line sometime on the 1st of February with the exception of the outdoor temperature sensor. That one may take a little doing to fix.

UPDATE 2/3/12: OK, I thought it was the outdoor temperature sensor causing this issue. It turns out that it is one of the ground loop temperature sensors. 2/3/12, all sensors are back on-line except for the two ground loop sensors.
