Set Back at night/daytime
Even though we were using a set back thermostat, it appears that the set back did not save any $$$ because the thermostat ultimatley allowed electric resistance heat in the morning, which it was supposed to prevent.
Because the electric heat came on, there was no savings from a set back(at nite or during the day while at work). This new control, by locking out the electric coils, should make a set back in temperature more economical.
