If you have a two stage heat pump then you will also utilize terminal y2 for the second stage.

Single stage furnace thermostat wiring.

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. 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. This controls the second stage of heating.

The new thermostat doesn t have these because it isn t designed for this type of installation. Conventional single stage systems will have one wire leading into w or w1 terminal for heating and one wire leading into y or y1 terminal for cooling. So that s the easiest way to identify single stage conventional hvac systems which would be furnace based or boiler based. Basically heating furnaces are of two types.

Single stage hvac system thermostat source. One which is common is the single stage heating system and the other one is multi stage heating system. The first and foremost thing you must do is to check what kind of heating system you are using at your home. A basic two wire thermostat can be compared to a simple single pole switch that you will find throughout your home only instead of you turning the switch on and off as required a mechanical or electronic temperature controlled mechanism is the operator of the switch.

That is a basic honeywell thermostat wiring diagram for a single stage heat pump. The thermostat only kicks in the second stage if the furnace can t maintain 6 to 8 degrees per hour. Cadet 16 7 amp 120 208 240 volt single pole electronic 7 day programmable wall thermostat in white. 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.

A two stage thermostat may need more wires than your current programmable thermostat. If not connect them in this manner. The terminals are usually marked r and w. The e and w2 hook ups are for the emergency heat relay and auxiliary heat control respectively.

The thermostat you purchased is designed for a single stage system such as an air conditioner and a single stage gas furnace. Verify that the red wire is connected to the r terminal green wire to the g terminal and white wire to the w terminal.
