Multi stage thermostat has more than one stage of heating/cooling output. The most common multi stage thermostat is two stage heating/cooling system – which has two output levels of heating/cooling. A two stage HVAC system will have a low setting & high setting suited for moderate climate conditions & extreme climate conditions. If the winter/summer is not on the extreme side, you just need to run your two stages HVAC on “low setting” which will adjust your room temperature gradually. If the climate is on extreme side, put your 2 stage thermostat on the “high setting” which will adjust your room temperature quickly.

Other than two stage systems (the most popular and common model), there are three stage & four stage systems – in multi stage heating/cooling systems. The cost of the system increases with the number of stages. In North America, most of the homes run on single stage or two stage heating/cooling systems. Single stage systems are the least priced & easy to install. But they’ve the disadvantage of lesser fuel efficiency & uneven heating. Two stage systems costs high to install (& setup) but they are highly efficient & they provide even temperature to all rooms.
