Prior to purchasing the new digital thermostat I removed the original one to examine the wiring configuration, knowing that this would provide information required in selecting a new digital thermostat.

(There are models that offer all sorts of daily/weekly programming, but that feature was not one that I desired.) The website was extremely useful because it allowed me to examine the "Installation Manual", which included a chart to coordinate the original wires with the correct connection posts in the new unit.

The further north you go in the US, the less you will encounter heat pump technologies because in the winter, the greater the temperature differences between the indoor and outdoor temperatures, the less efficiently a heat pump works. And basically, once you get much below freezing for an extended period of time, heat pumps become incapable of rapid increases in heat output, so they often have an third function setting labeled emergency heat; which uses an energy intensive set of heating coils to deliver a burst of heat when needed to rapidly increase your indoor temperature. Now here's the thing, when the emergency heat function kicks in, you can see those little gauges on your electric meter start to spin like airplane propellers...
