Product review (1 stars): Works only for a short time!
I installed this humidistat in February when I received it and it worked well. Heating season was over in a couple of months, then when I restarted the humidifier in November of 2013 it worked only for a week or so. When I checked the humidistat for operation on Thanksgiving no water was being released into the system. Same non-functioning humidistat problem as last winter. What, am I supposed to buy two of these things every year?
