Based on what I've read and discussions I've had with others, it seems that a two-stage thermostat would in fact take into account temperature differentials, etc., in determining when to switch to high fire, not just time.
Is anybody familiar with this issue, specifically with respect to White Rodgers thermostats? Apologies in advance if this is an obvious question to some of you. I am no expert on heating, but it seems that my two-stage system should be running with a multi-stage thermostat.
Thanks in advance for any comments. Dave
