And I would never keep a furnace operating in a condition where if a limit opens, it kills power to all external controls.
I'm just sitting here thinking of all of the possible scenarios that could occur by an open limit de-energizing the R terminal. Someone goes away for a day or two, the furnace limit opens because of 1) the filter finally hit it's limit...2) the blower motor fails...3) There is a power failure while the furnace is running full tilt...etc. So, the HO comes home to find a dead thermostat and assumes that there is a problem with the thermostat. This just doesn't make good sense.
