The heat anticipator is an electrical resistance wire mounted on a center disc connected to the bimetallic coil. It is adjustable to allow fine-tuning of when the thermostat turns the furnace blower on and off. - I'm still not sure what exactly gets warm from the resistance, the disk or the metal strip with the adjustable slider. Maybe, it's the bimetallic coil itself?
Basic thermostats for furnaces use a bimetallic strip, which is two strips of metal laminated together, As the temperature changes, the metals expand and contract, which switches the circuit on and off.
I wonder if I slide the adjustment to "shorten the cycles" by increasing the resistance to cause the bimetallic strip to heat quicker if it will actually have a reverse effect by causing the "low" mode where the fan stays on but the 50% gas cycles on and off more often? I'll experiment and report back later.
I've not yet checked with a stopwatch yet, so I'm not sure about the exact timing on the "high" burner activation. It seems to take a bit longer than 5 minutes to come on, sometimes ten minutes or more. I think it's just the timer countdown getting reset a few times from the thermostat bouncing back and forth within the preset time, until the room is cold enough it takes longer than 5 minutes non-stop "med" burner to start thermostat cycling, so now it switches to "high".
What do you think about my theory on how these RV Camper Furnaces' actual operation is more dynamic and complex then simple on and off switch by a heat sensitive coil?
Stay tuned, the snowstorm isn't over and it's already gotten more interesting than I care for.
Plus, the part for the RV Roof Replacement finally came in! It has been a unique experience to get to share after all this time and trouble.
