Auxiliary heat is the heat pump. Nothing wrong if you're using a heat pump. That's how it works, unless the system has another primary heat source.

My thermostat has both auxillary and emergency light on,both are green,what does that mean?


Aux light; This turns on when the auxiliary (second stage) heating is in operation
It turns on 1-6 F below first stage and is user adjustable

Emergency light; This light turns on whenever the emergency heat is manually selected
(Mode switch is in the EMER position)
While in the emergency Heat mode, the heat pump compressor is off,
and the emergency heat (same as the auxiliary heat) maintains the
set point temperature

Dual heat system, honeywell thermostat, auxiliary heat won't turn on


IT SOUNDS TO ME LIKE EITHER YOUR SYSTEMS LOW VOLTAGE WIRING IS INCORRECT, MOST LIKELY @ THE FURNACE. IT COULD ALSO SIMPLY BE THAT WHEN THE TECHNICIAN THAT INSTALLED THE T-STAT AT START-UP DID NOT GO THROUGH THE INSTALLER SET-UP & CHOOSE THE CORRECT SETTINGS FOR A DUEL FUEL SYSTEM. TRY THIS " SET THE THERMOSTAT TO EMERGENCY HEAT, WAIT A MINUTE OR TWO & SEE IF THAT TURNED GAS FURNACE ON. IF SO THEN IT'S A SIMPLE FIX IN THE WIRING OR PROGRAMMING & NOT SOMETHING MAJOR! GOOD LUCK!

What does the "auxillary heat"


Auxiliary Heat is used to turn the electric heat strips ON, If the heat pump is not working. Or if the heat pump can't bring the space temperature up to Set Temperature it will display Aux Heat ON....... Assuming you have a Heat Pump System with Auxiliary Electric Heat as Back up...... If the tech didn't install a jumper wire from AUX to W on the subase which is in back of the Display on the Thermostat.....you won't get Auxiliary Heat if the Thermostat is set for Auxiliary Heat. Other wise the thermostat will turn the heat pump on first and then the electric heat (Aux Heat) if it needs it to satisfy the set temperature....... Hope this helps

I'm installing a Honeywell Thermostat RTH2410. In Step 1 you need to identify the system type. I have a Carrier Heat Pump model FA4BNF030. Is this a heat pump with or without auxiliary/backup heat?


Auxiliary heat is electric heat that is put into the air handler on the inside of the house. Its used when your heat pump doesn't provide enough heat, but heat strips are not always used. To see if you have auxiliary heat, look inside and see if you have breakers on the front panel of the air handler or anywhere close. No breakers, no electric heat. Hope this helps!

Fujitsu heatpump 13 years old is not heating room as it used to.filters are clean.i have gauges and would like to know what pressures are good and what pressures indicate low refrigerant or worn...


The refrigerant and compressor are related in cooling the room.As for heating problem the thermostat needs to be checked.
if you're used to a certain temperature of air and your heat pump is producing much cooler air, take the following steps. (Note that a heat pump may go into a defrost mode to prevent icing. When this happens, it can temporarily output cold air. Also be aware that the heat pump will have to work harder to produce heat.)

1) First be sure the thermostat is set properly. Try raising the set temperature 5 degrees F. and waiting a few minutes.

2) Be sure the room-heating registers are open.

3) Check the heat pump filter. If it's dirty, change it.

4) Be sure the auxiliary heating elements are working . 

5) Clean the coils of the outdoor condensing unit.
If still the same problem then thermostat needs to be checked and replaced.
Thanks.

I have my thermostat set to 75 degrees however my house will only get up to 70 degrees. At night when the temp drops outside so does the temp in my house. For example I had my thermostat set for 75 degrees...


How old is your system?

If your system is a heat pump and is failing to keep up overnight during the colder weather. Or if it struggles to keep up at all, a few issues come to mind.


Obviously, the first and most common cause would be due to an undercharge of refrigerant. With an undercharge, your heat pump has lost efficiency and cannot properly remove heat from outside.


Other possible issues that come to mind are failed defrost cycle. If your unit is not defrosting properly and it continues to run non-stop, a freeze-up could occur on the outdoor coil. And the worse it gets, the worse your system will perform.

Another possibility is auxiliary heat or heat strips are not coming on at all. Depending on your thermostat, you would be able to tell if the thermostat is calling for auxiliary heat. If you are not getting any additional heat, then the heat pump may not be adequate for the space intended.


Other smaller factors may come into play such as incorrect defrost cycles. Possibly a mechanical component taking a break or overheating or maybe a mechanical failure such as failed compressor leaving the only heat you have as emergency.

You would have to take the rear trim quarter panel off to get at it . If you are taking about rear Heat - A/C . It's not under the dash ! Aux heat A/C has it's own unit in the back of the vehicle . 2003 Tahoe No Rear Heat Fix Suburban Yukon XL Repair This is to show where it is located , not to fix a no heat problem . How to get to the
Auxiliary Air Temperature Actuator
The auxiliary air temperature actuator is a 3-wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12-volt control values represent the opposite limits of the actuator range of motion. The values in between 0 and 12 volts correspond to the positions between the limits.
When the auxiliary HVAC control processor sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.

Item Part Number Description 1 — Air inlet door 2 — Temperature blend door 3 — Headliner airflow 4 — Auxiliary mode door 5 — Floor airflow 6 18476 Heater core 7 19860 Evaporator core 8 19805 Blower motor
The auxiliary A/C and heating system has the following features:
  • The auxiliary A/C and heating system is functional whenever the instrument panel mounted A/C control is in any position except OFF.
  • The auxiliary blower motor recirculates the air inside the vehicle. Outside air is not available to the auxiliary system.
  • Air is cooled and dehumidified by the auxiliary A/C evaporator core only if the instrument panel mounted A/C control is adjusted to a position that requires A/C compressor operation.
  • The temperature blend door and the auxiliary mode door are controlled by electric actuator motors.
  • Movement of the auxiliary temperature control between COOL and WARM causes a corresponding movement of the temperature blend door to mix air flowing through and around the auxiliary heater core.
  • Movement of the auxiliary mode control between PANEL and FLOOR causes a corresponding movement of the auxiliary mode door to direct air flow between the panel (headliner) registers and the floor duct.
---------------------------------------
I would say the auxiliary mode door (#4) electric motor is not wokring.

Heat pump auxiliary heat does not turn on


Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.
