We check houses for people with new gas furnaces, and digital thermostats, who are not here for months in the winter. Just recently we had two furnace shut-downs, and the power had NOT gone off in our area. Turns out that they have new digital thermostats, and the batteries had gone dead. Luckily we caught them before the houses froze up, it was in the single digits outdoors.
We managed to save their houses! But what the heck is going on???? Are these new thermostats not hard wired into the wiring, so that a doggone battery can cause a total failure in a new heating system, and freeze up a house???
I am astonished that an entire heating system is dependent on two AA cells?
People with Generac generators which come on automatically in a power outage, could still have a heating system shutdown???
Is this true? Then why arent these thermostats hard wired into the house electrical system to prevent this idiotic issue??
Yeah, Im only a grandmother, what do I know,,,,,,but I am very very concerned with this problem, 2 houses on one street with this issue within a month.
I have more info as of tonight,, I will post this info tomorrow, as its late and I am still very angry about this problem.
