SOURCE: heat pump works in emergency heat, but not in auxiliary heat

I set the thermostat for 70 degrees. It comes on always in auxillary heat and does not shut off when it reaches 70 degrees. It is a heat pump, I am assuming, it might be the thermostat? But when the air conditioner is on, it turns off when it reaches it's temperature.

WHAT DOES IT MEAN WHEN HEAT IS SET 66 AUX IS FLASHING


If it is a heat pump if the ambient I door temp is not than 3 degree s lower than 66 it utilizes the aux heat ( heat strips) to help the unit achieve your desired temperature set point faster. Also the heat pump does need help if trying to overcome really cold temperatures. Once set point is achieved the heat pump should be able to keep the home at the set point without aux heat. But the flashing may just be to let you know that the heat strips are in use at the current time. See if when the temperature gets close to your set temp if it goes away. If not a heat pump it may always flash to just tell you heat strips are in use. Some homes mostly trailers only have heat strips but on heat pumps heat strips are there to help heat pump get to your desired temp. But when your heat pump can maintain the temp without the strips is where it saves power. Also heat pump thermostat hVe emergency heat settings. This scares alot of people but if your heat pump isn't working and you have to switch it to emergency heat until you can get it fixed,. That means that the system is only using heat strips and not utilizing heat pump at all. Power bill may be a little higher but remember, most trailer homes only have heat strips and if you do not use emergency heat in this situation your heat strips will only heat home 3 degrees below set point on thermostat to allow heat pump to bring it up the other 3 degrees. If heat pump isn't working correctly you will always be 3 degrees colder than what you set you thermostat at. Maybe too much info but it's prolly just your aux heat on helping system achieve the desired temp you set thermostat too.

Why doesn't the compressor start in the heat mode


If the compressor is off and the heat coil is on - this is normal for the "E" or emergency heat setting. Check for proper connections between the Heat-pump, furnace(heat source) and the thermostat and that the thermostat is capable of controlling a heat-pump with secondary/emergency heat units. Thermostats designed for this have 4 settings: Cool / off / heat / E(emergency heat). in the "heat" setting, both the Heat-pump and Aux heat work together to maintain temperature. In the "E" setting, only the Aux heat source is used. The "E" setting should only be used in extreme cold - when the Heat-pump can no longer produce heat.

Our janitrol heat pump is freezing. there is considerable buildup of ice inside the pump itself on the coil. the fan still spins and still heats the interior of the home


Switch the thermostat from heat to Aux. or emergency heat till the outside unit thaws out. This will shorten the life of the outside unit considerable running it all iced up.

Goodman package- no heat below 30 degrees outside


I believe the unit you are describing is a heat pump. Heat pump are great when the temperature isn't below 30 With low ambient temps. outside it is much more efficient and comfortable to run aux. electric heat from the heat pump.

New heat pump system freezing, questioning wiring.


W1 and E on stat need tied together. When W1 comes on wire where all heat elements come on. On the outside unit defrost board set the 45-60-90 to 45 and see if that takes care of the frost problem.

I only have two settings. Which is which and how so?


I think you probably have a heat pump. Aux heat is electrical resistance heat coils that produce heat when the heat pump can not produce enough to keep the temperature up (caused by low outside temperature or a problem with the refrigerant system). This resistance heat can be switched on by the emerg. heat button. It also can come on automaticlly (sp) and will be indicated by the aux being shown on the thermostat. Sometime if you set the heat up several degrees by thermostat the aux will come on to help the system catch up to the desired temperature setting. The emerg. heat is a way to turn on the AUX manually. If you do not have a heat pump system then it is possible that you have a heat pump thermostat installed on a non heat pump system. Emergency heat and Aux are both the secondary.

Hope this makes sense1

Abbreviation definitions.


Economy Mode = EM
Auxelary Mode = AUX
in em mode heat pump does most of the work in aux either an electric heating element is used or gas depending on if it is gas or all electric

What's the difference between EM HEAT and AUX HEAT?


Sorry, neither of these answers are completely correct.
You have a heat pump (or the wrong thermostat). Let's assume you have a heat pump.

In air conditioning mode, it works like every air conditioner you have ever had, but...

In heat mode, it reverses its operation. Have you ever felt the air coming out of the outdoor unit of your A/C unit? It's hot, isn't it. And the air coming out of the indoor unit (out of the registers) is cold. Now for a heat pump to produce heat it simply runs the air conditioner in reverse and the heat comes out in the house and the cold is released outside. Neat, huh!

Here's the problem with heat pumps...when it is really cold outside the heat pump can't produce enough heat to heat your home. So it has an additional heat source called "Auxiliary Heat". This heat comes on automatically when the house doesn't get warm enough. The source of this heat is based on the region of the country you are in. North/Northeast generally have oil heat, other regions have gas, and still others have to use electricity to heat. In Texas, we usually use electricity as the supplementary heat on heat pumps. VERY EXPENSIVE!

Now the "Emergency Heat"...this is exactly as stated in Solution #2. This is manually turned on by YOU at the thermostat when your heat pump fails. This turns on the auxilliary heaters and turns off the heat pump (remember, the reverse air conditioner). Again, this can be quite expensive to run if your heat source uses electricity! Gas and oil may be cheaper. The emergency heat is only designed (normally) to keep the house livable (not comfortable) until the Heating Tech can get out to you and fix your heat pump.

Something else you should know. It is normal for a heat pump's outdoor coil to frost up during heating mode. It will detect this and go into DEFROST mode and melt the frost off the coil. While it is doing this, it will turn on the auxilliary heater to keep the air blowing in the house at a reasonable "warm" temperature, but it will not be as hot as normal. In fact, heat pumps produce a lower temperature heat than traditional heaters. So the air may feel cooler during heating than you are use to anyway. This is normal and is not a sign of a problem.

So what do you do: Set your thermostat to the temperature you want and set the controls for HEAT/COOL and FAN-AUTO/ON and leave the EMERG HEAT off unless your heat pump breaks.

As always, keep your filters clean and your outdoor unit's coils clean and free of debris.

Hope this explains your question for you!

MY HEAT PUMP SYSTEM WILL NOT WORK IN EMERGENCY MODE


the thermostat sub base has a place to connect a wire usually white to energize the heat strips when you push the stat way hotter than the house temp. that is why the strips come on in normal heat. it also has a terminal that is only energized in emergency heat and it also should have a wire connected to it so that terminal can supply power to the strips when the stat is switched into emerg heat . you can identify the terminal from the wiring diagram and if need be jumper w2 wire over to the aux terminal and it will work. they both go back into the airhandler and power the same strips. w2..................................................................................................w2 in airhandler to strips or w2...jumper to aux......................................................................................................................w2 in airhandler to strips.

Hi- Can not tell if my unites are straight cool / heat or a heat pump.


if you look inside the condenser unit outside,see if you see the big reversing valve,if not it is a straight cool,heat, the heat strip ins in the air handler so you would have to take the side panel off and look for the heat stripe,my the way heat pumps also have a aux.heat stripe just in case it does not get cold enough outside,hope this helps you-mike
