"The most recent cold spell went ok. The week before, we had a power outage of just under 3 hours, and the only reason we didn't have a lot of frozen pipes and major loss was because the jace woke me up to tell me! The power at my house was only off for a couple of seconds, but when the emg class alarm didn't clear promptly I came right in at 4AM (it was about ten degrees below 0!) and opened all interior doors to try to keep the coldest corners of the place above freezing. One tricky spot hidden inside a wall froze and leaked when it thawed out later that day, but I was here on top of it to minimize the damage quickly and am properly insulating and air-blocking that space now.  But let me leave you with no doubt, the new controls probably paid for themselves that morning, no joke!!"  Tim Gordon CARLISLE CONGREGATIONAL CHURCH
