Single Stage Furnace Wiring

Remember the study from ashrea in 2006.

Single stage furnace wiring.

Modulating furnaces provide homes with more precise temperature control and less dramatic temperature fluctuations than single stage and even double stage furnaces. Most of that from the blower motor. Standard ac with standard air handler and single stage backup heat control wiring standard air handler wire size. That means the furnace operated about 10 longer than a single stage furnace.

A two stage or variable speed system may only be operating at a single speed because the thermostat or control system doesn t allow for two stage wiring. Strip the brown thermostat wire back one half inch and connect it to the w2 terminal on the furnace. Single stage vs two stage 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.

They showed an 11 higher electrical consumption from a two stage furnace. Low cost equipment for basic home heating. For more information on the differences between a one stage and a two stage furnace try this short video. Furthermore this thermostat wiring diagram is specifically for a system with two transformers your system likely only has one transformer as most typical residential systems only use a single transformer for control.

So if on average your single stage furnace ran for 10 minutes the two stage furnace would run for 11 minutes. That is a basic honeywell thermostat wiring diagram for a single stage heat pump. In furnace terminology stages refers to the levels of heat output a furnace can provide. This furnace has only two settings.

A dual fuel system which is comprised of a gas furnace and a heat pump should be connected to a thermostat or control system that can accommodate the specific heating set points. If a furnace is one stage or is too big for your house again it will kick off more often and spend less time filtering the air in your house. A single stage furnace the most basic design available has a fixed gas valve and a single speed blower fan motor. This controls the second stage of heating.

More air moved means more air filtration. Always refer to your thermostat or equipment. If you have a two stage heat pump then you will also utilize terminal y2 for the second stage.
