Mechanical wall thermostat lag and overshoot and the anticipator part 1

A description of how the mechanical thermostat lags behind the room temperature and overshoots room temperature. This results in wide temperature variations in the structure. The anticipator is installed to reduce these temperature variations. The operation of this part is discussed. This video is part of the thermostat anticipators playlist.
This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
