Does ecobee3 work with heat pump?

ecobee thermostats are compatible with heat pump and dual fuel setups, provided your system uses a single O/B wire.

Does ecobee work with 2 stage heat pump?

ecobee thermostats only support up to two stages of heating and cooling. If you see a wire connected to your current thermostat’s W3 or Y3 terminals, we recommend booking a pro near you to install your ecobee.

How do you wire a thermostat for a heat pump?

Quote from the video:
Quote from Youtube video: Left over that you can use to switch a terminal out if there is ever a future problem. So the thermostat. Color code for the heat pump thermostat over to the indoor air handler is that.

Does R go to RC or RH ecobee?

If you only have one R wire (That includes R, Rc, and Rh), you’ll insert it into the Rc terminal on your ecobee. With dual-transformer systems you’ll have two R wires—one from the cooling transformer (Rc) and one from the heating transformer (Rh). Learn how to install an ecobee thermostat in a dual-transformer system.

Should I allow the heat pump and AUX heat to run simultaneously?

The system is designed so that both can operate simultaneously. As long as the HP is producing some heat, it’s more efficient to use the HP for whatever Btu’s you can garner and allow the aux heat to be just that, auxiliary rather than primary.

Where does B wire go on ecobee?

Most of the time, the wire labeled B goes into the O/B connector on your ecobee thermostat and is used to control the heat pump’s reversing valve, which switches between heating and cooling modes. However, on some thermostats, the wire labeled B is the Common (C) wire.

How do I know if I have a 2 stage heat pump?

Quote from the video:
Quote from Youtube video: You will have a wire or Y to the Y to wire. Will essentially control whether you're at first stage capacity. Or if you bump up to 100% capacity which will be second stage.

Does ecobee work with 4 wires?

The PEK requires your system to have the following wires: • 4 wires: W, Y, G, and R (or Rc or Rh), or • 3 wires: Y, G, and R (or Rc or Rh) 1. Remove the cover panel from your HVAC equipment.

What is auxiliary heat on ecobee?

Auxiliary heat is basically a complimentary system attached to your HVAC that kicks in whenever your heating system cannot heat the room to the set temperature on its own.

How do you wire a heat pump ecobee?

Quote from the video:
Quote from Youtube video: Your first stage compressor wire will go into y1. Second stage into y2 your fan will be installed into the g terminal. And your auxilary heat will now be installed into the w1 terminal.

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.

Can I use ecobee without C wire?

If you’re lacking a C wire and have at least four wires at your thermostat to work with (refer to this article if you only have two wires), you’ll want to install the Power Extender Kit (PEK).

Does ecobee show when AUX heat is on?

How to minimize the use of auxiliary heat with a heat-pump on your ecobee thermostat. This Alert is known as an Aux Heat Runtime Alert and it indicates that the ecobee has noticed a pattern of the auxiliary (Aux) heat activating a certain number of hours (or more) within the day.

Should I leave my heat pump on all the time?

While heat pumps are the most cost effective way to use electricity to heat your home during the cooler months, leaving them running day and night is not economically efficient. According to Energywise, you should switch off your heat pump when you don’t need it. This is to avoid excessive energy waste.

How does AUX heat work on heat pump?

Aux heat automatically turns on when the outside temperature drops and prevents the heat pump from drawing in enough heat to reach the set thermostat temperature. In other words, aux heat is a supplemental component to a heat pump; they work together to ensure your home is comfortably warm.

At what temp does AUX heat come on?

This is when the outside is around 35-40 degrees and the indoor temperature is around three degrees cooler than the thermostat setting. The thermostat will sense this and turn on electric heat strips automatically turning on the “AUX” heat light.

What kind of thermostat do I need for a heat pump?

You need a special thermostat for a heat pump because it needs to be able to communicate with the reversing valve when changing from heating to cooling. Heat pumps rely on outside air and electricity. Heat pump thermostats will typically have a fifth wire explicitly for the reversing valve.

When should I turn on auxiliary heat?

Auxiliary heat is needed when…

Heat pumps are highly efficient to about 32°F. Below freezing, your heat pump simply can’t draw enough heat from the cold air outside and will kick on its auxiliary heat mode to generate heat for your home.

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.

Will heat pump work below freezing?

Yes, heat pumps will still work even below freezing, especially modern ones. Good heat pumps will still perform efficiently at 25 degrees Fahrenheit.
