Question about Honeywell Heating & Cooling

2 Answers

I installed honeywell R845A 1030 as per diagram on its cover - hot blk to #1 and circl load to 3&4 and aquastat load to 6&5 putting the blk conductor of both load wires on the odd # terminal i.e. 3&5 -I only have juice across the line conductors and nothing on other two even when system is calling for heat--i took cover off same product someone else installed in this basement [on another identical gas fired hot water boiler] and the hot black was jumped across the 4&5 terminals and the blk conductors from the loads were tied to 3&4 and the neutrals were all tied together from the pigtail from the #1 line terminal - the owner of that apt said the system works fine for over 2 years - can some one straighten me out

i would be really better if u could give the diagram .........

The diagram is wrong as I believe you are grounding one, wire it exactly as you saw it wired in the other basement and let me know what happens. If you can post a picture of the diagram if it doesn't work, then I can see what is the difference better.

thanks and good luck

I have installed honeywell aquastat relay per instruction manual on my dunkirk xeb-4 lp boiler furance with honeywwell ignition unit s8610u but it wont ever start the exhaust fan checked everything several...


If aquastat wirings are ok, and control module had been set up properly, the the furnace should start.
Check if bypassing the control the furnace starts, if it starts then check aquastat wirings.
If it depends on the furnace, check the valve, the safety sensor and the ignitor.
Here is the guide to set up the Aquastat control:

I have a Weil mcLain Gold gas furnace and the Amtrol WH-7L hot water maker. I heat alot with an indoor woodstove and if the furnace is not being used I cannot get any hot water. However, when the furnace...


You should download & review the manual for Amtrol Boilermate products here.

Page 12 of the manual begins examples of wiring between the Boilermate and aquastat (also gas valve and multi-zone relay), that is usually mounted on the boiler. In order to use it correctly, you'll need to determine which aquastat (or other device) your furnace has. You should be able to locate this info on the inside of the aquastat cover. The Honeywell Triple Acting aquastat is very common and looks like this:

11_29_2012_7_17_38_pm.jpg
The cover is held by a single screw on the top, bottom or front (depending on the model you have). The inside should have wiring information along with the model number. Compare the model number with the wiring diagram for it in the Boilermate manual.

Make sure power is OFF before continuing.

Check that all wires are terminated and undamaged. Make sure terminal screws are not loose. Tighten any found to be loose.

The orange wires are connected to a switch that is normally OPEN but CLOSES to start the boiler when the hot water has cooled. It is also used to operate a "power vent" for a minute or two both before ignition and after flame out for safe pre and post purging of the combustion chamber of furnaces that lack a chimney.

Blue wires are connected to a switch that is also normally OPEN but CLOSES to start the boiler when the hot water has cooled. When the switch connected to these wires is CLOSED, ignition happens instantly. There is no delay for purge so when these wires are used to start a furnace, it should be one with a chimney - not a power vent.

For additional help with your particular installation, you will need to provide information concerning the wiring diagram in the manual that applies. Otherwise, there are simply too many variations to walk through.

I suspect that the switch(es) that are connected to the orange (or blue) wires - or the device (aquastat or multi-zone relay box) is not operating as expected to start the furnace.

The troubleshooting section of the manual that seems to apply best is the section: Boiler will not operate when calling for hot water on page 27 (if you want to try some of their suggestions while waiting for additional replies).

I hope this helps..

Heil outside fan motor 3 wire rd/blk/br new dayton motor 4 wire blk /br /purpule /brown with white strip Need help on wiring


Hi, the new motor takes its own capacitor to run it. This is what the 2- brown wires are for, one will have a white stripe. You will need to but a seperate run capacitor for this motor, a 5 uf, 7.5, or what ever it calls for. they should have told you when you bought the motor. It will have to spade connectors on it where the brown wires connect alone. Use the dual capacitor if that is what you have for the other 220 volt wires.Black and purple will be your 2 hot wires.You can connect either one to the old capacitor on the fan terminal and the other to the load side of the contactor, so when the contactor closes it will energize the motor.Or, take both the black and the purple wires and to the load side ( outlet side ) of the contactor, connect one to one side and the other to the other side. The line side is where your 2 hot wires that connect to the contactor from the incoming wires from the electrical box, you want to be on the other end. I would connect the black to the contactor load side and purple to the old capacitor as long as the old wiring is still on it as it has to be fed by a hot wire from the contactor. Each wire, blk, and purple has to have 120 volts to each one and you can get this a couple of ways. The contactor has several terminals that are not used and if you wire them on the outlet side, they will only be energized when the contactor is closed on a call from the stat, very easy to do. You will have to get a coulple of crimp on connectors to put on the ends of the wires, but the brown ones should already have them for this capacitor. Do not try to put the brown wires on the old run capacitor as you will burn out the new motor! Go get the small run cap for these 2 wires for about $10. I know that you can do this wiring change just remember the blk is hot 120, and purple is hot 120, = 240.volts. If you have removed all of the wires from the old capacitor, then use the contactor to connect to. The compressor wires must stay on the old run cap on the hermetic side and this old cap. must be fed by a hot wire from the contactor to the common terminal, that is marked with a C..If you look at the new motor diagram, it will show you also. Please dont forget to rate me as I know you will be kind, and I will check in on you to see how you are doing. Get this capacitor and it will run. This is a must!! Please keep me posted.
Sincerely,

There should be a wiring diagram on the back of the access panel. If you can't read it, check online for model wiring diagram. Don't guess, you may cause more expensive damage.

What would the correct high and lo and diff settings for the Honeywell L8124A Aquastat I have a wood fired boiler with the oil fired boiler side by sides,


I would say high if you need cooling. If the tempature is cool enough for you then set it to low.If you are hot and need more cooling then high.

I have a Honeywell L7224U1002 aquastat and I am unsure how to turn the temperature down. The water is 180 degrees.


I fixed it by holding in the 3 puch buttons for 3 seconds and then I was able to lower the temp by using the up and down buttons.
