We have alot of new jobs here lately that have the T350 communicating tstats. Some of them have the WebsAX module, some dont. We are looking at having to pull some of these out because the local rep has some jobs setup where you cant even adjust the thermostat setpoint. Searching the forums I found that these stats use Lonspec. I have a list of other distributors in the area that I can get it from. My question is what will I need besides Lonspec? Any words of advice or insight would be appreciated.
