in response to Re: Loss of temp sensors due lighting., posted by Bob
Bob, I've done the same - put in some offsets into the WEL to match temp readings from a highly accurate digital temp measurer.
This is the case for my EWT/LWT sensors, where I have a P/T port within inches of the mounted sensors, and is the case for my air sensors (LAT, SAT, rooms).
It's the EWT/LWT sensors that I look for best possible accuracy because the differential is used to compute KBTU/hr and HE/HR. I've learned the sensors are affected by many things, even including the temperature of the connected wires. Hence, my offset corrections are not so much an indication of sensor error as they are of correcting for error induced by installation. My air sensors don't have many offset corrections.
Best regards,
Bill

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
