Does the ecobee3 Lite work with a heat pump?
HEAT PUMP (AIR OR GEOTHERMAL) WITH AUXILIARY HEAT
ecobee3 manages auxiliary heating through the W1 & W2 (if there is more than 1-stage of aux heat) terminals outputs.
Does your heat pump use an O wire or B wire?
If you have a heat pump and your thermostat doesn’t have a separate wire labeled O, then the wire labeled B should be connected to the Nest thermostat’s O/B connector.
Can I use ecobee without C-wire?
Even though it comes with an adapter for missing c-wires, ecobee is what we’d pick even for systems with a c-wire. If you’ve got a 24v HVAC system but no C-wire, check out the ecobee product line. Every ecobee ships with an adapter that you can install yourself at your furnace to make up for a missing C-wire.
Do smart thermostats work with heat pumps?
Yes! A majority of TSTAT systems are produced to operate with heat pumps. There are several 2020 Nest, Ecobee, and Lux smart/programmable thermostats models on the market that work well with heat pumps.
What wire controls AC on thermostat?
The yellow wires underneath your thermostat connect to your compressor. They control your air conditioning system. The yellow wires terminate at your compressor contactor via an air handler. The yellow wires connect to the Y terminals on your thermostat.
Where does Aux wire go on ecobee?
If you have a heat pump system with auxiliary heating, you will normally connect the wire labelled AUX/AUX1 or W2 to the ecobee’s W1 terminal. If you have two stages of AUX heat, connect the AUX2 wire to the ecobee’s W2 terminal.
Does ecobee work with 4 wires?
Even though Ecobee does not require a c-wire, you still need to have a 4-wire thermostat cable because they require a power extender kit. You will connect the wires from your furnace to the power extender kit and then to the thermostat.
Is ecobee compatible with carrier?
The ecobee smart thermostats Powered by Carrier can be connected to the Carrier Connected Portal enabling contractors to remotely diagnose and troubleshoot system issues and errors.The ecobee SmartThermostat with voice control also includes an ecobee SmartSensor in the box.
What color is o’b wire?
Orange Wire for O and Dark Blue Wire for B, depending on the installer of the heat pump and the manufacturer.
How many wires do you need for a heat pump?

| B | Blue | Change-over relay to heat relay |
| A | Heat and cool active to any relay | |
| L | Emergency heat active lamp |
What are the wires in a thermostat?
5 Wire Thermostat Wiring (Any HVAC Device Air Conditioners, Heat Pumps, Furnaces, etc.)
- Red wire for power (24V).
- White wire for heating (connected to W or W1 terminal).
- Green wire for fans.
- Blue or yellow wire for cooling (connected to Y).
- Black wire for C or Common wire.
Does ecobee work with stranded wires?
If you have a high-voltage setup, a smart thermostat isn’t going to work. For Ecobee thermostats, 120V and 240V systems (such as baseboard heating) will not work at all.Google Nest also points out that its thermostats won’t work with systems that use stranded wires or stranded wires that are connected by a wire nut.
What happens if you wire a thermostat wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
Why is my heat pump blowing cold air when the heat is on?
Defrost mode basically means your heat pump temporarily switches to cooling mode. This forces the outdoor coils to heat up, melting any frost or ice that has built up. And because the heat pump switched to cooling mode, it will blow cold air into your home for a few minutes.
What temperature is a heat pump not effective?
between 25 and 40 degrees Fahrenheit
Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
What wires call for heat on a thermostat?
The common wire, sometimes referred to as the c-wire, is what’s responsible for delivering constant power to your thermostat. For programmable thermostats and smart thermostats, c-wires are essential for setting a schedule or having your heat or air conditioner turn on at a desired temperature.
What color wire is for heat on thermostat?
white
FIVE WIRES
The wires are typically arranged as follows: red for 24-volt hot, white for heat, yellow for cooling, green for the fan, and blue for common (although the common wire may be a different color).
What color is the Y1 wire?
