Does a heat pump require a special thermostat?
Why do heat pumps require a particular type of thermostat that’s different from an air conditioner’s? The reason is that heat pumps must control both heating and cooling. To switch from one to the other, the thermostat needs to signal the reversing valve to change the direction of the flow of refrigerant.
At what temperature does a heat pump go to auxiliary heat?
Most heat pumps are designed to automatically switch to AUX heat when the indoor temperature is 3 degrees colder than the thermostat setting. For example, let’s say that you wake up to a cold home (62° F) and immediately raise the thermostat to 68°.

Does heat pump run when auxiliary heat is on?
If your aux heat indicator is on, it means your heat pump needs a little help reaching its target temperature setting. Aux heat comes from the same heat source as emergency heat, but aux heat works together with your heat pump, so it’s less expensive than emergency heat.
Can you use any thermostat with a heat pump?
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.
Why does my heat pump go to auxiliary heat?
The AUX heat setting on an HVAC unit usually turns on when you need heat fast. If this secondary heating system is constantly running, it may mean that the weather outside is very cold or that the thermostat is set higher than normal. It’s also possible that a part of the heat pump is malfunctioning.
Will smart thermostats work with heat pumps?
Most smart thermostats are compatible with heat pump systems. What is worth noting is the installation process is a little tricker as there are additional wires to manage. Below we discuss the differences in wiring along with specific features to look out for in a heat pump thermostat.
What does auxiliary heat on the thermostat mean?
If you’re wondering what the auxiliary heat feature on your thermostat means, it’s basically a supplement heat source. To start, the job of a heat pump is to take air from the outside your house, warm it and then blow it throughout the different parts of your home.
When to use a heat pump with auxiliary heat?
When outside temperatures drop too low to allow the heat pump to extract heat from the frigid air, some systems switch on a backup heating system to supply the rest of the heat needed to reach the desired temperature inside. While some heat pumps have that auxiliary heating capability, others do not. Heat Pumps With Auxiliary Heat Vs.
What are the features of a heat pump thermostat?
This programmable thermostat for heat pump with auxiliary heat, gives you temperature accuracy of about 1 degree that means you have got the option to maintain the temperature of your home within one degree of where you set it. It has some other features too, like: It has a 7 day programmable schedule with four periods for each day.
How many wires does a heat pump thermostat need?
Where a standard AC thermostat uses four wires (hot wire, compressor and outdoor fan wire, indoor blower wire, battery wire) to run the unit, a heat pump thermostat requires a fifth wire to handle the change in the reversing valve.
Where is the thermostat on a heat pump?
Locate your thermostat control panel. The thermostat is generally located in a central location in the house. This is the spot where the system measures the temperature of the surrounding air and determines whether or not to turn on the heat or begin cooling.
Does the heater work without a thermostat?
The warmth of the engine is what makes heat inside your car when you turn on the heater. So, if you drive without a thermostat, your engine will never reach its optimal operating temperature and your heater may blow cold air. If you live in a warm climate, this should not be a problem.
What does auxiliary heat mean on my thermostat?
Aux on the thermostat stands for auxiliary heat. Auxiliary heat is the electric heat strip in your air handler that is supplemental heat. Emergency heat is the same thing as auxiliary heat. Auxiliary heat/ Emergency heat help the heat pump keep up when cold outside or the temperature differential on the thermostat is large.
What is the emergency heating setting on my thermostat?
The emergency heat option on a thermostat is a manual setting , not an automatic function initiated by the heat pump thermostat. The purpose of the emergency heat setting is to bring the backup furnace online immediately to deliver 100% of the home’s heating requirements while simultaneously locking out the heat pump.
