Mastering Em Heat: Honeywell Thermostat Tips

If you have a Honeywell thermostat in your home, you may have noticed that it gets quite warm to the touch. This is due to the fact that the thermostat uses an internal heat source to keep the temperature inside of it consistent. While this heat source does not usually pose a problem, there are times when it can become too hot and cause the thermostat to malfunction.

If your thermostat is getting too hot, there are a few things that you can do to fix the problem.

If you have a Honeywell thermostat, you know that it can be quite handy in regulating the temperature in your home. However, you may not know that there is a setting on the thermostat called “Em Heat.” This setting allows you to use your thermostat to control the amount of heat that is emitted from your furnace.

By turning this setting on, you can save money on your energy bill and keep your home more comfortable.

What Does Em Heat Mean on Honeywell Thermostat?

If you see “EM” on your Honeywell thermostat, it means that your system is in Emergency Heat mode. This mode is typically used when your primary heating source (usually a furnace or heat pump) is not working, and your backup heating source (usually an electric heater) is being used instead. Emergency Heat mode can be turned on manually by pressing the “EM Heat” button on your thermostat, or it may be turned on automatically if your primary heating source fails.

Either way, the “EM” indicator will light up to let you know that Emergency Heat mode is active. In most cases, you’ll want to switch back to normal operation as soon as possible to save energy. However, if you’re in a situation where emergency heat is necessary, it’s good to know that your thermostat has this feature and can keep you comfortable until the problem with your primary heating source is resolved.

Is It Ok to Run Emergency Heat?

Most people think that running their emergency heat is going to be really expensive and they are worried about it. The truth is, if your home is properly insulated, running your emergency heat shouldn’t cost you that much more on your energy bill. In fact, in most cases, it will only add about 10-15% to your bill.

So, if you’re thinking about whether or not to run your emergency heat this winter, the answer is probably yes!

What’S the Difference between Heat And Em Heat on My Thermostat?

On a typical home thermostat, there are two types of heat that can be selected: electric heat (em heat) and regular (heat). Each type of heat has its own set of pros and cons that should be considered when making a decision on which to use. Electric Heat (Em Heat):

Pros: -More efficient than regular heat because it doesn’t lose any heat through ductwork -Can be used in homes without access to natural gas

-Heats up quickly because it directly heats the air Cons: -More expensive to operate than regular heat because electricity is more expensive than natural gas

Why is My Em Heat On?

If your EM is on, it’s probably because the ambient temperature in your room is too low. The EM will automatically turn on when the room temperature falls below 68 degrees Fahrenheit. So, if you want to save energy and keep your EM off, make sure to keep your room warm!

What Does Em Heat Mean on a Thermostat?

If you’ve ever wondered what that “Em Heat” setting on your thermostat means, wonder no more! Em Heat stands for emergency heat, and is typically used when your home’s primary heating source (usually a furnace or heat pump) is not working. When you turn on the Em Heat setting, your thermostat will use electric resistance coils to generate heat, which can be quite expensive.

So, unless you absolutely need it, we recommend avoiding the Em Heat setting on your thermostat!

How to Turn off Emergency Heat on Honeywell Thermostat?

How to Turn off Emergency Heat on Honeywell Thermostat

If your home is equipped with a Honeywell thermostat, you may find that the emergency heat feature is turned on at some point. Here’s how to turn it off: First, locate the switch on the thermostat that controls the emergency heat.

It should be clearly labeled. Once you’ve found it, flip the switch to the “Off” position. Next, you’ll need to adjust the temperature setting on the thermostat.

If it’s currently set to “Emergency Heat,” change it back to your desired temperature. Finally, be sure to check that the furnace is turned off before leaving your home or going to bed for the night. The last thing you want is for your furnace to continue running while you’re not there!

Honeywell Thermostat Em Heat Vs Heat

If you’re wondering whether to use the heat or em heat setting on your Honeywell thermostat, you’ve come to the right place. In this blog post, we’ll take a detailed look at the difference between these two settings so that you can make an informed decision about which one is right for your home. The “heat” setting on a Honeywell thermostat is used to maintain a comfortable temperature in your home by heating the air as needed.

The “em heat” setting, on the other hand, is designed to save energy by only heating the air when it’s absolutely necessary. So, if you’re looking to save money on your energy bills, the em heat setting is probably the way to go. Of course, there are some trade-offs with using the em heat setting.

For example, your home may not be as comfortable as it would be if you were using the heat setting because the air isn’t being heated continuously. Additionally, it may take longer for your home to reach its desired temperature when using em heat because the thermostat will only turn on the heating system when it’s absolutely necessary. So, which setting should you use?

Ultimately, it depends on your personal preferences and needs. If saving money is your top priority, then em heat is probably the way to go. But if comfort is more important to you than saving a few dollars each month, then you might want to stick with using theheatsetting.

Emergency Heat Setting

If you have a heat pump, you may have an emergency heat setting on your thermostat. This is a feature that allows you to use your backup heating source (usually electric resistance heat) in the event of a power outage or other emergency. Emergency heat is typically used for a short period of time until power is restored or the emergency situation has passed.

It is important to note that using emergency heat can be more expensive than using your regular heating source, so it should only be used when absolutely necessary. If you think you may need to use your emergency heat setting, first check to see if there is an interruption in your power supply. If there is no power outage, but your heat pump isn’t working properly, you should contact a qualified HVAC technician for service.

Honeywell Heat Pump Thermostat

If you’re in the market for a new thermostat, you may be wondering if a heat pump thermostat is the right choice for your home. Here’s what you need to know about Honeywell heat pump thermostats to help you make your decision. What Is a Heat Pump Thermostat?

A heat pump thermostat is a type of thermostat that is specifically designed for use with a heat pump heating and cooling system. Heat pumps are becoming increasingly popular in recent years as an energy-efficient alternative to traditional HVAC systems. How Does It Work?

A heat pump thermostat works by managing the operation of the compressor, fan, and reversing valve in a heat pump system. The compressor and fan work together to move air through the system, while the reversing valve controls the direction of airflow. By regulating these three components, the thermostat is able to maintain comfortable indoor temperatures year-round.

Why Choose Honeywell? Honeywell is one of the most trusted names in home comfort, so it’s no surprise that their heat pump thermostats are some of the best on the market. With features like auto changeover (which switches between heating and cooling modes as needed), precise temperature control, and energy-saving settings, Honeywell thermostats give you complete control over your home’s comfort level – all while helping you save money on your energy bills!


If your home is like most, the thermostat is one of the most important devices in keeping your family comfortable. So, when it breaks, it can be a real pain. One of the most common issues with thermostats is that they stop working correctly due to em heat.

Em heat, also known as electromagnetic interference, is caused by things like cell phones, microwaves, and even some types of lightbulbs. When these devices are used near your thermostat, they can cause the internal components to overheat. This can lead to problems with the display, inaccurate temperature readings, and even complete failure.

Fortunately, there are a few things you can do to reduce the risk of em heat damage to your thermostat. First, try to keep mobile phones and other devices away from the unit. If possible, avoid using them in the same room or even on the same floor.

Second, don’t use compact fluorescent lightbulbs (CFLs) near the thermostat; they produce a lot of em heat and can shorten its lifespan significantly. Finally, make sure your thermostat is not located near any sources of strong electromagnetic fields (EMFs), such as power lines or electrical appliances. By taking these simple precautions, you can help ensure that your thermostat will continue to work properly for years to come.
