Moving heat- In heat mode, your heat pump is like an air conditioner working in reverse to pull heat from the outside to inside your home (the opposite of how it works in cooling mode). What Is a High-Temperature Limit Switch on a Furnace? The Emergency Heat or Auxiliary Heat setting is the second stage of your heating system that is used when the temperature is too low for the heat pump to be able to remove heat from outside, typically below 35 degrees Fahrenheit. Maybe it won’t turn on, or it no longer heats up appropriately. When the heat pump can no longer maintain the desired temperature setting, then the auxiliary heat must come on to assist. Many air handlers have more than one breaker that provide power. Typically the auxillary heat will be on and off perodically, you'll know when its on because you will feel warm air coming from the registers, the heat pump by itself w/ no auxillary heat will usually only send out 90F temperature from the registers, give or take 5F - … Once the source of the airflow restriction is eliminated, reset the lock-out by cycling high-voltage power to the air handler.
