Thermostat For Modulating Gas Furnace

A modulating furnace is the most energy efficient type you can buy.

Thermostat for modulating gas furnace.

This type of furnace will aim to keep your home within one to two degrees of your desired temperature by adjusting its flame in slight increments to the changes it detects. It has an inbuilt schedule which you can use. From top to bottom inside and out and every angle in between we ve thought of everything to bring you efficient and dependable indoor comfort. The most common types of thermostat on the market today use low voltage wiring.

Top quality modulating furnaces can achieve an incredible afue rating of up to 98. According to the thermostat manual amplitude of this signal is about 10 vdc frequency is 1 hz and the pulse width is variable 350 to 950 milliseconds in steps of 50 msec. And since every modulating furnace has a variable speed blower they consume less electricity too. With the vehicle analogy the car would travel at either full stop 0 mph maximum speed 120 mph or local street speed.

Speaking of variable speed blowers the variable speed blower is the fringe benefit of a modulating furnace. A low voltage thermostat or control system is commonly used to connect with. Modulating furnaces provide homes with more precise temperature control and less dramatic temperature fluctuations than single stage and even double stage furnaces. In other words they are the most cost effective when it comes to long term energy savings.

These low voltage wires are typically very thin similar to wiring for doorbells or telephone jacks. Modulating furnaces only burn as much gas as you need to heat a given space which can make a gigantic difference in your heating bill. A double stage furnace is more closely akin to the single stage furnace than the modulating furnace. Then came the modulating furnaces.

It s too bad that trane and other manufacturers it appears are going down the road of proprietary thermostats for their highest end modulating solutions. Industry first patented features and exclusive design make the rheem prestige series modulating r98v gas furnace a smart option. Enjoy savings through maximum efficiency. It is mainly designed as a gas furnace thermostat to control the gas furnace or ac.

The modulating thermostat outputs a pulse width modulated signal on its v terminal that controls the gas valve on the furnace over a 40 100 power range. Conventional gas forced air furnaces. Like the single stage it too has maximum high and off settings but it does have one additional low stage that allows for a slower less energy gobbling stage of heat. Modulating gas furnaces gas furnace manufacturers have for many years been working on modulating furnaces to make furnaces more efficient before modulating furnaces the highest rated in efficiency were two stage gas furnaces.

However it is not compatible with multistage systems or electric baseboard heating systems.
