I have two ecobees going to the same furnace which serves two zones and is controlled via dampers.
2 stage electric furnace thermostat.
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.
O b energize to cool controls the reversing valve.
E electric heat override.
Works with 2 stage or multi stage heat or cool.
You ve to check if the thermostat supports all these fuel types or not.
Heartland quality heating cooling installs all of their 2 stage gas furnace s with a wall thermostat that controls the staging this gives the homeowner complete control and provides the greatest level of comfort without the wall thermostat the equipment guesses when to stage the levels of heating.
Most new thermostat units are compatible with heat pump thermostats baseboard heater thermostats furnace thermostats and boiler thermostats.
I have enough conductors in the wire from the thermostat to the furnace for the configuration.
The ecobee terminal block has a w1 and w2 connection.
G fan on off.
The thermostat you purchased is designed for a single stage system such as an air conditioner and a single stage gas furnace.
You ll need to identify if your home is fitted with 1 stage 2 stage direct line voltage 24mv or zone heating and cooling to determine which thermostat will be compatible.
Energy source compatibility central furnaces are usually powered by natural gas electricity or fuel oil.
2 stage conventional cooling system will have wires leading into terminal y and y1 or y1 and y2 two stage thermostat 2 heat 2 cool option.
But this thermostat is actually wired as 1h 1c system as there is a jumper wire connecting w1 to w2 and another jumper wire connecting y1 to y2.
W2 heat stage 2 inside 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.
This means that the thermostat can be used if you have a multi stage heating or cooling system.
Two stage furnaces start in the first stage when the amount of heat required is lower instead of reaching full capacity all at once.
I have a 2 stage ruud furnace.
