Thermostat For Modulating Gas Furnace

Top quality modulating furnaces can achieve an incredible afue rating of up to 98.

Thermostat for modulating gas furnace.

It is mainly designed as a gas furnace thermostat to control the gas furnace or ac. Then came the modulating furnaces. A double stage furnace is more closely akin to the single stage furnace than the modulating furnace. Enjoy savings through maximum efficiency.

This thermostat comes with a 5 2 programmable memory meaning you can program for 5 weekdays and 2 weekends separelty. 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. In other words they are the most cost effective when it comes to long term energy savings. Imho it seems that a better architecture would be to have the thermostat become a very simple device and locate the smart controls for modulation at the furnace air handler.

Conventional gas forced air furnaces. 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. With the vehicle analogy the car would travel at either full stop 0 mph maximum speed 120 mph or local street speed. And since every modulating furnace has a variable speed blower they consume less electricity too.

Up to 98 cents of one dollar you spend goes toward heating your home. Speaking of variable speed blowers the variable speed blower is the fringe benefit of a modulating furnace. However it is not compatible with multistage systems or electric baseboard heating systems. 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.

Industry first patented features and exclusive design make the rheem prestige series modulating r98v gas furnace a smart option. Modulating furnaces provide homes with more precise temperature control and less dramatic temperature fluctuations than single stage and even double stage furnaces. It has an inbuilt schedule which you can use. 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.

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. These low voltage wires are typically very thin similar to wiring for doorbells or telephone jacks. A low voltage thermostat or control system is commonly used to connect with. The most common types of thermostat on the market today use low voltage wiring.

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.
