PM. This may help unless U’r thermostat is
newer and has its own setback/programming
features, which means it’ll probably have
more than two wires. Keep in mind that my
fix is nothing more than a switch, in series
with the thermostat, which allows (or
prevents) the low voltage from the thermostat
to be applied to the gas control valve.
Another solution is to buy a programmable
thermostat in the $25-50 range.
