How To Turn Off Auxiliary Heat On Honeywell Thermostat?

Honeywell thermostats are well-known for being some of the most efficient temperature control systems available. They also have a tendency to use for auxiliary heat.The majority of people have noticed “Aux heat” on their Honeywell thermostat and wondered why it is there. The more informed will tell you that running the thermostat on ‘Aux heat‘ is costly.That’s precisely why you need to know how to turn off auxiliary heat on Honeywell thermostat.

What Is Auxiliary Heat On The Honeywell Thermostat?

Auxiliary heat, or ‘aux heat’ as many people know it, is a system that enables the Honeywell thermostat to crank up the heat without waiting for temperatures outside to increase.

Thermostats work by reacting to the temperature in their surroundings. That means they have to detect the prevailing temperature situation in the surroundings to regulate the house temperature accordingly. So when the temperatures get below a certain point in your home, a Honeywell thermostat would automatically turn on auxiliary heat. Auxiliary heat doesn’t wait on the outside temperature to fall for it to kick in.

Auxiliary heat is, therefore, a spectacularly effective and fast way to heat your house. The only issue is that it will increase energy costs. And that’s why most people would love to know how to turn it off.

With the increased need to save, no one would want something to add on to the costs of running a home. That’s why you need to know how to turn off auxiliary heat on your Honeywell thermostat.

Why is the Auxiliary Heat Coming on?

Certain situations are standard thermostat operation if the auxiliary heat comes on. You need to know this situation to avoid the auxiliary heat coming on for the tiniest temperature changes.

It is okay to use auxiliary heat mode when using the thermostat’s heat pump in defrost mode. That allows your thermostat to heat your living quarters without exposing you to the cold.

Another situation where it is okay for auxiliary heat to kick in is when the exterior temperatures go below freezing point. That’s a common occurrence during winter. Your external heating pump will struggle to push in warm air that can heat your house. That’s where the auxiliary heat pump will be most helpful.

Most users will want the temperature to be considerably low when they sleep. That might be a different story in the morning, though. To adequately heat the house faster, the auxiliary heat will need to kick in.

That’s why most users will power up their thermostat by about three degrees to make it heat the house faster. That will then cause the use of the auxiliary heat function.

Another situation when it’s normal for the auxiliary heat to turn itself on, the thermostat is working for some time, but the temperature still doesn’t change. The auxiliary heat will take over since that will mean the external heat pump isn’t working well.

The above is a perfectly normal situation for the auxiliary pump to step in. However, there might be other situations that might result from malfunction. If you notice that auxiliary heat seems to step in each time without any of the above situations necessitating it, there might be an issue.

Troubleshooting will enable you to restore the thermostat to regular operation.

How to Stop Auxiliary Heat From Coming on Honeywell Thermostat

We have already seen that aux heat, although affecting at heating your house, can be pretty costly. There is no need to worry, though, since there is something you can do about it.

Make Your House Warmer

Generate a warm atmosphere in your house. With the house being warm, it will prevent the aux heat from kicking in. You can warm it up by adding wall insulation or letting the sun enter your home through the windows whenever possible.

Besides that, you could also turn on electrical appliances famous for generating lots of heat when in use. The dryer and the oven come to mind when you think along these lines. Keep them running for a bit longer.

Reduce the House Temperature

When you get a thermostat, there is a specific temperature that you will need to set as the home temperature. If you reduce this temperature to something between sixty-eight and sixty degrees Fahrenheit, aux heat won’t kick in. That’s part of the thermostat’s programming.

Of course, that might make your home colder, but you can compensate for it by wearing warm clothes. It is the bills you are trying to cut down, so anything goes.

Setting a high temperature will necessitate the deployment of auxiliary heat since the external pump won’t be up to the task. That will lead to higher energy costs due to auxiliary heat stepping in.

Avoid the Emergency Heat Setting

Not many people know that there is a difference between emergency heat and auxiliary heat. Emergency heat is like a contingency plan for when the usual heat pumps break down and aren’t working well.

Emergency heat works with heat strips instead of the heat pump. Auxiliary heat, on the other hand, works with the heat pump and the heat strips. Emergency heating might cause the need for auxiliary heating. So if you can avoid it, then it’s best to.

Frequently Asked Questions

Do All Honeywell Thermostats Have Auxiliary Heat Functions?

Some Honeywell Thermostats have auxiliary heat functions, while others do not. If a thermostat does not have an auxiliary heat function, it is important to make sure that the thermostat is connected to a heating system in order to maximize its efficiency in combating cold temperatures in a room.

Why Is Auxiliary Heat So Bad?

Auxiliary heat is bad because it does not have enough capacity to adequately heat the building, which leads to cracks in the walls, discomfort of inhabitants, and expensive utility bills. Auxiliaries are able to provide for an additional 25% of the energy that a system can produce. This prevents the building from having cycling problems in which the fans run all day long in order to keep up with demand.

Can I turn off auxiliary heat?

No, you cannot turn off auxiliary heat. Auxiliary heating is a backup for your primary heating system in the event of a power outage. It does not function properly when it’s turned off.

Why does the auxiliary heat keep on working?

The auxiliary heat keeps on working because it is used to maintain the desired room temperature. The thermostat interprets this as a need for more heat, no matter what the condition of the heating system.

Why does the auxiliary heat keep coming on?

The main reason auxiliary heat would keep coming on is if there are freezing temperatures outside your house. That’s a common sight in the winter. Aux heat will kick in to maintain comfortable temperatures in your home.

What is the typical temperature when aux heat steps in?

Aux heat will step in when the temperatures are too low. For most people, that’s at 40 degrees Fahrenheit.
