Emht Thermostat

What does EMHT mean on my thermostat? I have some HEAT / COOL / FAN / EMHT settings, but I don't know what they do.

This is a full line thermostat.

You will run the second phase of your heating system, ie H. Your first step is a second stage heat pump, electric or gas heater. If you know there is a problem in the first stage, you can skip the normal operation. Active if the set point is within 3 degrees of ambient temperature, or after a while if the first stage is not reached.

Emergency heating

Emergency heat switches on heat pump thermostats are used by many people. The point is, most people do not understand what an emergency heater is and when to use it. Many people think that heat pumps do not work in cold weather and should use emergency heating when it is very cold ... Wrong!

What is an emergency heating system?

Simply put, all heat pumps in the northern climate [below 35 degrees] require an additional heat source. It usually comes in the form of an electric resistance heater. This is an all electric heat pump. It can be a gas, oil or water backup system. The backup heater is also called backup heater or backup heater, the first step is just a heat pump. The backup heater is also used as an emergency heater.

Different systems have different options for determining when the second stage of the heat pump is turned on, but it is always automatic. Therefore, both phases work together in the colder months and there is no need to set the thermostat for emergency heating. Now we know what a backup heater is and how it is used for emergency heating.

So when should you use an emergency heater?

As the name suggests, it is only used in emergencies. It is used when there is a problem in heating the first stage [heat pump heat]. In other words, if you find that your device is cold and not warming up properly and you go outside and see a tree fall and destroy your heat pump, switch to emergency heating. It will be a good time to do it.

Mainline thermostat

The EMHT is an emergency heater. Normally, the heating system activates air vents and vents to keep air circulating, but emergency heating is a constant flow of air. It is not designed for casual use because it is too expensive to operate.

Your emergency heater activates a coil (such as a toaster) that adds extra heat to support your normal heat source.
