I have just installed a Hunter programmable thermostat which operates by a battery. While this inexpensive unit works beautifully, I am curious, just in case the thermostat breaks or run out of power (let's assume I have no backup battery in my home) in the midst of a show storm in Feburary, is there a way I can wire something up to turn on the furnance and get heat instantly ?
I remember seeing the following wire connections (please correct me if I remember incorrectly) :
G Y Hc Hr B W
Can I jump any two of these terminals and gets heat ? For your info I live in a new house which has a electronic ignition furnance and a central a/c unit.
Thanks in advance for a knowledgable answer.
