If you need to use it, it would suggest that the outside air changeover thermostat on the outdoor unit is either defective or not set correctly. The Em. Ht. switch simply brings on either the strip heat, or in the case of a dual-fuel application, the furnace, to supplement the heat pumps ability when it gets colder outside. A "Balance Point" calculation will determine what temperature this changeover should occurs at. The calculation involves the intersection point of two lines on a graph. One line represents the increasing btuh needs of the building as the outside temp. decreases. Line #2 represents the output of the heat pump relative to outside air temp. (Output decreases as oa temp. decreases) Operation below the intersection of the lines requires the use of supplemental heat. Acurate setting of the changeover tstat assures high efficiency operation down to the Balance Point and saves you money. lc
What else can I help you with?
Is a programmable thermostat good to use with a heat pump system?
A programmable thermostat works fine with a heat pump. Just remember that a heat pump does not heat as fast as a furnace because of the lower BTU ratings so do not set the thermostat as far back as you normally would. Also make sure to buy a thermostat that has heat pump terminals.
What type of thermostat does a heat pump with auxilary heat use?
Any brand or make will work if it is 2 heat 1 cool thermostat
How can a heat pump be optimized for efficient performance during the winter season?
To optimize a heat pump for efficient performance in the winter season, you can: Ensure proper insulation in your home to minimize heat loss. Regularly clean and maintain the heat pump to ensure it operates efficiently. Set the thermostat to a consistent temperature to reduce energy consumption. Consider installing a programmable thermostat to control the heat pump more effectively. Use a backup heating source, such as a furnace, in extremely cold weather to assist the heat pump.
What does e heat mean on a Bryant thermostat?
The "E Heat" setting on a Bryant thermostat typically stands for Emergency Heat. This setting is used to activate the system's backup heat source in case the primary heat pump is not able to meet the heating demands during extreme cold weather conditions. It is important to use this setting sparingly as it consumes more energy than the primary heat pump.
How do you reset a goodman heat pump?
To reset a Goodman heat pump, follow these steps: Turn Off the Thermostat: Set your thermostat to the "Off" position to stop the system from running. Switch Off Power: Locate the circuit breaker for the heat pump, typically labeled, and turn it off. Alternatively, use the disconnect switch near the unit if available. Wait for 5-10 Minutes: This allows the system to reset and clear any error codes or malfunctions. Turn Power Back On: Restore power at the circuit breaker or disconnect switch. Restart the Thermostat: Set the thermostat to your desired mode and temperature. If the issue persists, check for specific error codes or call a professional technician.
What does the EM heat mean on your thermostat for your central AC heating unit?
If you have a heat pump A/C unit then you have auxillary heat and emergency heat. The EM stands for emergency heat, which is using only your electric heat strips or gas heat, depending on your system. The auxillary heat uses your compressor inside of your outside unit. Say the house is 60 degrees inside and you set your stat to 70, the temperature difference is so great that if the heat pump alone cannot satisfy, then the auxillary heat would come on to assist the heat pump. Say you were to get a leak in either your condenser or evaporator coils, your heat pump would not work on the regular heat setting on the tstat. In this circumstance you would want to use just the emergency heat until a service tech can evaluate the system.

When should you use em heat on the thermostat?
EM (or emergency heat) can be used if you have a problem with your other heat source such as a heat pump. In most cases, you will not need this but what it does is bi-passes the primary heat source and allows your secondary heat source (normally your furnace) to become the primary.
How do you disable the reversing valve on a heat pump so you can run with a straight cool air handler?
Depending on the brand of air conditioner, it is either the removal of the signal voltage to the valve, or the constant application of signal voltage to the valve. Most brands on the market are powering the reversing valve in the cooling mode. This would be easiest as you would have to make no changes if you wish, and only switch your thermostat to Emergency heat instead of heat, effectively not using the heat pump. On Rheems and Ruuds for example, the unit is in cooling mode unless the reversing valve has voltage applied to it. If you have a Rheem or Ruud, no change would be necessary except to change your thermostat to a correctly wired standard version rather than a heat pump specific version. Many electronic thermostats have this built in. Like above, you could also simply use Emergency heat instead of normal Heat switch at the thermostat. Either way, heatpump wiring can be tricky for even a good service tech if they aren't accustomed to working with heat pumps. So its best to have this done by a service company that works with heat pumps a bit.
What If your pilot light on your furnace is on but the furnace is not working?
My wall furnace has an overheat safety switch. It's up near the top on the side of the unit. If the exhaust vent gets too hot, it will trip the switch off. I use a small screwdriver to reset the switch by pushing the little red button. The switch when activated shuts the thermostat to off. By resetting it, the thermostat will now work.
What is an wall thermostat?
A heat sensitive electrical switch that maintains the temperature and controls the on-off action of the heat source. NOTE: thermostats should only be used with gas appliances that have been tested and listed for use with thermostats.
When to use emergency heat setting on a heat pump?
Heat pumps don't work well when its below freezing point temperature's
