Question about Air Conditioners

Open Question

I purchased a siemens temperature monitor #QAA2071, the monitor comes in two pieces a base and a front. The wiring terminals on the base are 1, 2,3,4,5,6,7,and8. The terminals on the device and wiring diagram are G, GO, U..., I...,G..., C pos, and C neg. Where do I apply 24vdc to the base and where do I connect my 4 - 20 ma output on the base

SOURCE: No output voltage on circuit board terminals 1,2,3,and 4.

I think those are your thermostat connections and are probably 24 vac. Check the output of the transformer and make sure it is 24 vac. If it isn't make sure power is supplied to the input of the transformer.

Siemens rdj10rf/set-gb problems with


There seems to be a common fault with the relay in the base unit box that's wired in to the boiler. If the black triangle is showing, the remote is demanding heat. If the two lights (green and orange) on the base unit are both lit, then it is paired and knows that heat is being demanded by the remote. However the relay sticks and doesn't actually supply current to the boiler. It can also stick in the on position so the house just keeps getting hotter. I've found that a couple of firm taps with my knuckles on the front of the base unit usually solves the problem temporarily, but if it keeps happening I think you need a new base unit (although I think you can only buy the complete kit).

Air conditioning condensor will not run from thermostat have to go outside remve covers and jump thermostat connection . Then runs fine and cycles problem is intermitant


If it was me I would make sure the weed wacker hadnt attacked those wires as they leave the area leaving the house making their way to your condensing unit. Next, follow those wires back to your furnace control terminal area. Blower vibration can cause those little wires to break over time. Take care not to cause a break. Next, pull the thermostat off its base wall mount and jumper the red and the yellow wire, sometimes there is a blue color wire instead of yellow. If the unit outside comes on after this trick, make sure rc and rh are jumpered together on the thermostat terminal base and if they are then its your thermostat. One last thing, if someone has changed that thermostat since last cooling season, the thermostat wiring should be red to r terminal, white to w, green to g, blue or yellow to y terminal. Again rc and rh are usually jumpered. There are exceptions and at the very least see that the red wire is under the rc terminal.

I have an early 80's mobile home with an "intertherm gas atmospheric furnace" pilot light is lit but can't get the furnace to "fire". Seems as though the limit control is stuck open. ...


If your pilot light is lit then I would first check your thermostat. Make sure it is on heat setting and fan is on auto, turn stat up to where it should be calling for heat. If you don't get burner to light remove front cover from thermostat and see if it has a mercury switch, if it does move temperature selector up and down and see if you can see a spark in mercury switch vial. If y ou cannot see a spark remove screws that attach t-stat to base.Remove carefully and disconnect wires that go to r and w terminals on stat base. Temporarily connect these two wires together. This should make burner light if you have power to thermostat. If burner does light disconnect wires and replace thermostat. Also if you have a volt meter check across these two wires and see if you have power there. Should be around 24 volts a.c. If your thermostat has a fan on setting try that. If fan runs you know you have power to furnace The gas valve needs 24 volts to operate and inside the electric control box in furnace there is a transformer to step down 110-120 supply voltage to 24 volts. If transformer is working you should be able to hear a low buzz or humming sound. You can also check across gas valve terminals when t-stat is set for heat, you should read about 24 volts. If you have 24 volts to gas valve and it is not opening then you need to replace gas valve. The main purpose of the limit switches is to turn blower on when temperature in heat exchanger reaches fan on temp,shut off blower after burner shuts off and heat in heat exchanger reaches fan off temperature, and limit if temperature exceedes set point without blower coming on. I hope this helps you. Thanks

Where do the wires from the compressure go to on main base


Wiring up a compressor
The Start wire goes to one side of the run capacitor it will be the only wire on that side of the capacitor.
The Run wire goes to the terminal side (T1 or T2) of the contactor, it will have another
wire from that terminal to the run capacitor which is the opposite side of the start wire.
The Common wire will go to the other side of the contactor (T1 or T2).
Start Kit
Start from the capacitor to terminal #1 on start relay There should be another wire from
here to start on the compressor.
Common from contactor ( T1 or T2) to terminal #5 on start relay. There should be a wire from this terminal to the Common terminal on the compressor.(there will not be a capacitor in this circuit)
Run from the other side of the contactor ( T1 or T2) to the start capacitor and from the other
Side of the start capacitor to terminal #2 on the start relay. There should also be a wire from this
Terminal to Run on the compressor.

Rewire air conditioner controls


Assuming "Window Unit" with rotary switch.
L1 (smooth part of line cord) to thermostat 1, thermostat 2 to overload (black disk) from overload to Common( C) terminal on compressor.
From Run (R) terminal on Compressor to Common (C) terminal on dual capacitor. From Start (S) terminal on Compressor to "Herm" terminal on capacitor. From fan motor to # 4 on switch = Medium Speed, to # 6 on switch = High Speed, from fan motor to # 7 on switch - Low Speed. Brown wire from fan motor to (F) on dual capacitor, white wire from fan to (C) on capacitor and L2 (ribbedwire) (N) to (C) on capacitor

OK. Here is a Trane Weathertron BAYSTAT240 thermostat wiring picture. This heat pump w/ electric (emergency) heaters is running right now. Notice the G terminal has green wire, the R terminal has red wire, the white wire is jumpered from W to X2, etc. The black wire loop you see in the center hole is unconnected.

_1412.jpg
This unit is adjusted by leveling the base - loosen the screw to the left of "R" and the one to the right of "F". Twist the base clockwise to RAISE the indicator. This makes the mercury in the switch turn ON at a different temperature. Remember to tighten those 2 screws again.

You will have to experiment several times to make the unit read exactly right. If the tech installed the base exactly level, the unit would read right (it says here).

Remote thermostat off several degrees


if you can locate the sensor the remote thermostat is sending the signal to you may be able to get terminals to wire a thermostat to let me know if it is possible what the terminal letters are normally G is fan, Y is cooling, w is heat, red is 24v hope this helps

My lennox heating system will not kick on when the temp drops and I have to manually set it every time....what to do?? Im freezing


Sounds like your t-stat is failing you. Here is a test you can do. Take the front cover off. Locate the R terminal and the W terminal. Get your self a short piece of wire small diameter say 18 gauge. Now take your wire and jump across the two terminals hold them there and if you hear your furnace kick on then the t-stat is bad. let me know what you find out. ken

I know this is late but I had to add a solution to this problem since I had the exact same problem and was able to solve it. The probelm is not your control board. On these units, the heat pump compressor will not kick in unless the temperature you set on the control panel is within 2-1/4 degrees (or 4 degrees depending on your unit model. Otherwise, the unit locks out the compressor until the electric heat coil bring the indoor temperature up to that level - and then will switch the compressor back on for heat pump operation. So the problem is not the control panel or the compressor, it the electric heat coil. The coil has two manual limit switches on it that may be tripped and should be checked. The coil can be easily accessed by shutting down the power, removing 4 screws around the air outlet, pushing the screen up and sliding the panel out the top. The power wires can remain in place while the limit switches are reset. Hope it works.
