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

My Haier 7000BTU portable AC unit is blowing hot air into the room from the back. We have the drain hose in and draining, so what might be the problem?


The drain hose is only to be used when the unit is in Dehumidifier Mode. In AC/Cooling Mode, there needs to be water in the tank to keep the coils cool. It is not recommended to use continuous drainage in AC Mode. My personal recommendation is do not operate Cooling Mode & Dehumidify Mode at the same time. As the dehumidify mode generates heat. Not something you need to be doing when you're trying to cool the room.

Hope this helped you and thanks for choosing FixYa.

Compresser for air cond wont kick on no digram for fuse panel could be missing fuse


The fuse might be there but its burnt out. Change the fuse/relay and see. if nothing happens then it could be the actual compressor itself that is out.

Hope that helps.

03 Sunfire need to locate the vacuum pump for the vent knob on the air cond.


The vacuum pump is the engine. It uses vacuum from the intake manifold on the engine to power the accessories. The vent knob basically is a switch for the vacuum, to give you different positions for your vent/ac/heating ducts, giving varying levels of vacuum to achieve them. problems with them working or not working usually stem from a leak in a hose, or a vacuum hose that has been disconnected. The most common vacuum leaks are where hoses are hooked up to something, right where the nipple ends inside the hose. They tend to crack there the most often.

RUUD HVAC UNIT - HEAT STRIPS COME ON WITH THE A/C


What you are talking about I think are the strip heaters in the Air Handler this must be a Heat Pump system right??? If so please check your thermostat and make sure it is not in EMRGY HEAT mode.. One other note there is a 2 stage bulb system inside the stat if it is too cold outside and the heatpump on its own cant keep up with the call for heat the 2nd bulb closes and turns on the heater as a supplumnetal heat also these will come on or should come on when the unit goes into defrost.. plz let me know what it is you are trying to test and i can walk you thru it.. Also need a model # off the A/H to get a Wiring diagram
