    could be a low voltage problem if no voltage t-stat will not work or the relay componets as well.

    have you checked the circuit breakers? sounds like no line voltage. There may be a breaker at on in the unit itself also. Steve

Hi I have a hb2400vd2m20 air handler and need to know what wires are needed to hook up to my thermostat its a Honeywell, as of the moment there is no heat pump it just the air handler running. I know there...


Honeywell 5000, 8000, 8000 iaq, prestige, round dial analog, digital Honeywell redlink. 1 heat 1 cool thermostat 3 heat 2 cool thermostat. does the stat u have do conventional a/c and heat pump. red wire is hot wire 24 volts not heating its your 24 volt control power. this will be r on your board and t-stat and red wire. y is for cooling mode and is yellow and will be noted y on both board and t stat. green is fan on the indoor furnace and will be g on board and t-stat and the wire is green. blue is the common side of the transformer labeled b on both board and t-stat. I did not see brown on your schematic I looked up I seen orange which is your reversing valve wire for the heat pump whether its calling for cooling or heat this is what changes the flow of Freon to make it to the indoor coil as warm Freon or cold when called for in heat or cool. the thermostat if a vision pro 8000 needs to be programmed in the installer mode which if this is the t-stat u have u need to read through the heat pump section. the green hooked to the orange doesn't look right on the print but that's the breakdown. http://www.manualslib.com/manual/277678/Haier-Hb2400vd2m20.html?page=11#manual heres your schematic

HE heat pump won't talk with old air handler?


The fact is, the air handler supplies the voltage, blower, and electric heat. In order for the heat pump to work correctly, the wiring from the thermostat and heat pump need to be hooked up right to the air handler. The thermostat is what tells which component to come on. If the fan stops, but the condenser keeps going, you either have a faulty fan relay on the air handler, faulty thermostat or wiring, faulty wiring at the heat pump, or the contacts on the new unit are sticking, which is highly doubtful considering it is working now. I hope I have helped you understand this a little more. Good luck and don't let them push you around, get someone that knows what they are looking at.

I have a Ruud air handler and i'm trying to use a


The 44360 tstat can be used for single stage Heat pump use only. Unless you are in an environment that has greater than 40 degF outdoor temperatures year-round, you will want to return that tstat and obtain a multi-stage Heat Pump tstat. The standard system is 2-stage......1st stage is Heat Pump Compressor and 2nd stage is the backup electric heat.

Hope this helps. Good Luck. :-)

What does aux mean on a honeywell Thermostat? the heat doesn't seem to be working but warm air is comming from the vents and the heat pump fan is spinning just not enough to match the temp. it's set too....


The aux switch is for electric heat banks installed in the air handler. Depending on the outside temp. it may not be efficient to run in heat pump mode but in aux. or emergency would run the electric heat in the air handler.

We have 2. LA125HV w/ 1 condensing 1. air handler


I could not find a "fault code" list for the LA125HV but for thier Multi Split Units LG lists code CH7 (C7) as "Indoor Unit is Set in Different Cool/Heat Operation Mode." So maybe your air-handler tihinks it's in Heat mode will the compressor is in Cool mode, or vice-versa....

My air handler comes on ,not the outside unit when my thermostat is in the off position even if i turn the thermostat down to 50 and have it turned off the air handler comes on for about 5 to 10 minutes...


If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.
