Honeywell F1-9406 Zone Valve

I think I have some old zone valves on my hot water heating system (gas fueled boiler).

Where/how can I find wiring/instructions for Honeywell F1-9406 Zone Valve?

 

That does not look like a Honeywell number. Could be just a very old one. How many terminals or wires on the valve. Pix would help.

 

I agree, it looks more like a manufacturing or a date code.(But that would make it the 6th week of 1994)

 

Dance387,
If you can take some pictures of the zone valves & post them on photobucket or similar photo hosting site & provide a link to the pictures here, we can probably be of more help.

 

The part number I posted earlier (Honeywell F1-9406) is on the motor/transformer thing inside the zone valve, and might be part number for that.

If that is a case, I am not sure if this is a Honeywell Zone Valve or just just Honeywell motor/transformer thing.

Also, this building is divided into 6 zones. There are no problem with 5 zones and the Zone Valves for those 5 zones have 4 wires connected to the Zone Valve.

The Zone Valve for the 6th zone, where we have a problem, seems to have only 2 wires connected to it.

(All 6 Zone Valves have another wire going by them, without being connected to the Zone Valves.)

I do have some pictures, and I am including Photobucket URLs here.

But this is the first time I am using Photobucket. So, if I do something wrong, please email me at *********, and I will directly email those pictures to you.

Thanks for all your help, everybody.

Good shots & a big help. If you follow the red wires from the working zone valves, you should find one from each valve all tied together & going back to a T terminal on the aquastat. The same with the other red wire from each valve.

I think you will find that if another zone is calling for heat, zone 6 might also get heat but not if only zone 6 is calling. From what I can see, it looks like zone 6 has no way to tell the boiler to fire or to bring on the circulator.

Again, from what I can see, I would say you need to replace zone 6's valve with one like those found on zones 1 thru 5.

Has zone 6 ever worked by itself?

 

Thanks again, Grady, for all your help.

We just bought the building and this is our first winter here. And the previous owner is out of the country and we have no way to contact them. So, we do not know when was the last time Zone 6 was able to call for heat, tell the boiler to fire, or tell the circulator to run.

Is it possible that somebody wired the Zone 6 valve wrong or incomplete? If so, how can go about fixing/completing the wiring?

If I have to replace the Zone 6 valve, what am I asking for at the parts store?

What is the aquastat and what does it do? (Is that the part I gave part number F1-9406 for? In my last post, I called it motor/transformer thing.)

I am assuming there is one circulator for all 6 zones, on the boiler somewhere. Is that so?

Thanks again for all your help, Grady.

 

If you look at the valve for zone 6, you will notice there are only two wires coming from it. All the others have 4 wires. You wll need to replace the powerhead with a 4 wire head. The Honeywell part # is: 40003916-048.

Often parts houses don't stock just the powerhead or it is more expensive than a whole valve. If that is the case, just buy a 4 wire valve & swap out the powerhead. I think this can be done without having to drain the system.
When you get it installed, tie the red wires to the red wires of the other zone valves & the yellow wires to the wires currently attached to the existing zone valve. You might want to put the existing zone valve powerhead on a shelf in case a motor craps out on one of the other valves. Changing the motor is a 5 minute job for me, might take you 15 minutes.

The number you gave is a manufacturer's date code for the zone valve motor. The aquastat is mounted on the boiler with wires going to the burner & to the circulator. Most likely, you only have one circulator.

With a few more pics of the boiler & nearby piping I should be able to pick out the circulator & aquastat.

 

Thanks again, Grady.

You thought buying the whole valve would be easier/cheaper that buying the powerhead with a 4 wire head (The Honeywell part # is: 40003916-048). Do I need to know the Honeywell part # for the valve? Or will the part store be able to sell me the right one?

Also, how do I go about swaping the powerhead? And how do I know if this can be done without having to drain the system?

Below is a link to a few more pics of the boiler & nearby piping/wiring. (Two of the pictures are for a water heater near there.) If you can help me idenify circulator/aquastat/other things here, that would be great help.

Thanks, again, for all your help.

 

In order for me to be able to tell you the number of the whole valve, I need to know what size the pipe is on which the valve is located. The easiest way to determine the pipe size, if you don't have calipers, is to snug an adjustable wrench onto the pipe, slip the wrench off, & use a tape measure or ruler to measure the gap between the wrench jaws.

Re: Photo 100-0051. At the bottom left of the boiler is the gas valve. The red device in the center is your circulator. To the right of the circulator is the pressure relief valve. Behind the copper pipe from the relief valve is a boiler temperature & pressure gauge. Mounted on the top right corner of the boiler is the aquastat. Right of the aquastat, mounted on the wall is a transformer to power the zone valves & thermostats.

Photo 100-0053 shows your boiler's vent damper.
