It can possibly work that way. Might be better off bundling together all of the commons from the stats separately and running an extra tstat wire from the bundle to the transformer. Even though it's going to the same place, it would be a more direct path.

I've always wired Honeywell zone valves this way. That is how I was taught. I recently had a Emerson Sensi wifi tstat acting goofy. I using the same common that I'm using for all the thermostats W therminal to complete the circuit. Thermostat will call for heat and then it won't.

I have a 3 zone boiler setup like this. What would be the best way to make this type of system "smart"? I was thinking of getting some thermostatic radiator valves to replace the poptop valves. But then that won't send the send a call to the boiler as well. Can you recommend any equipment?

@JerseyMikeHVAC

8 ай бұрын

Thermostatic radiator valves are more of a zoning type of concept that still have to be manually set. The idea is to adjust each radiator to produce a certain level of heat room to room. If you want smart technology, I would recommend a circulator pump for the boiler that integrates smart technology, such as something like this: www.xylem.com/en-us/products--services/pumps-packaged-pump-systems/pumps/wet-rotor-circulators/heating-cooling-circulators/ecocirc-20-18/ You'll certainly have to do some homework to make sure it's compatible and works with your system, but that's where I would start looking.

Ive never worken on these honeywells before, so correct me if im wrong please, it appears that they are using the r and w circuit in the stat to complete the common circuit from the motor back to the xformer common. Is that correct? If so wouldnt there be no 24 volts on the r terminal in the tstat? Thats where im getting confused. I understand a tstat is just a switch that is either opened or closed but ive always seen 24v on R to C for instance,and then W to C when calling for heat, Y to C for cooling ect. or if no common on stat i would expect to see 24v from R to W when no call for heat,24v on R and Y on no call for cooling ect. And then no power reading when there is a call on those. So i guess im missing something here.

I love the 5 steps! I have 3 tacos, with 1 transformer and 1 circulation pump. The wiring is a mess. How similar is the wiring for a taco to your 5 step video?

A Question load from the transformer, can it go through the TT from thermostat first and then go to the zone valve. I know currently the way is to connect the yellow wire from zone valve first and then goes through to the TT on the thermostat. Thank you for the helpful video.

@JerseyMikeHVAC

The thermostat and the T&T are on separate 24 volt circuits, but yes, you can wire the load off of the transformer to the thermostat R terminal first and then to the zone valve motor from the W terminal via one of the yellow wires. The other yellow wire would then go back to transformer common. If I remember correctly, I believe the last diagram in the description shows this arrangement.

Hi Jersey Mike, awesome, clear video, thank you for doing this… There is a problem with one of the zone valves in our heating system since it was 'serviced' a couple of years ago. When the 1st. floor thermostat controlling the heat to the front of the house turns on the heat, it also activates the zone valve for the 2nd. floor bedrooms. The other two zones, including the one for the 2nd. floor bedrooms, work properly each controlling the heat of their own zone. Before attempting to make any changes to the existing wiring, I looked at your Zone Valve Wiring Cheat Sheet. The first discrepancy found is that the RED (load) cable from the transformer is connected to the WHITE cables from each thermostat, and the WHITE (common) is connected to the YELLOW cables from each zone valve. I traced the RED cables coming from each of the thermostats, and they connect to the respective YELLOW cable of their zone valve. Any suggestions of what could be causing this malfunction? Will it be safe to go ahead and disconnect all the wires and start from scratch following all steps from your cheat sheet. Thanks in advance

Turn off all of the thermostats. Turn on only the thermostat for the 2nd floor bedroom that you're having an issue with. Does that thermostat alone properly control the boiler turning it on and off? Or does nothing happen? Also, does red connect to R and white to W at the stats?

Hi, thanks for getting back to me, I greatly appreciate it. Each thermostat worked properly with their own zone valve, turning on and off the boiler. Red connected to R and white to W at the stats, checked OK. These is what I did next: Second floor bedrooms thermostat on and set the temp to 50F. First floor front zone thermostat on and set the temp at 90F. Second floor zone valve lever feels closed to the touch, does not move, but water flows through it. Then: Second floor bedrooms thermostat on and set the temp at 90F, the zone valve lever moves freely back and forth. First floor back zone thermostat on and set the temp at 90F, works fine. It appears that the second floor zone valve does not close properly. But, why when the first floor back zone thermostat is set at 90F, if the second floor valve is not completely closed the water does not flow through it? They are all connected to the same hot water supply line. 🤔

@JerseyMikeHVAC

8 ай бұрын

The wiring seems fine then. I have seen pressure changes in flow through changing manifold configurations as zone valves open and close, sometimes causing scenarios where a zone valve would not fully close but it would heat up or not just depending on which of the other zones were calling. It's a little weird but I've seen it. You can try to flush through the zone valve by opening and closing it manually a bunch of times as water is flushing through it, but it may be time to replace the valve body.

I'd have to know a lot more about all of the equipment you have there to really begin to give answers, But the TT circuit Is the burner circuit that fires up and shuts down the boiler. R, W and C are generally terminals of another circuit that is commanded by the thermostat. That circuit gets acrivated by the thermostat, which in turn activates the TT circuit to fire the boiler. So generally they aren't the same circuit. There are a lot of different arrangements out there though as fat as equipment, which would be relevant when it comes to ow to wire it all up.

Actually, now that I think about it, do you have a Crown Boiler by any chance? Some brands have R-W-C terminals on the control boards in the boiler like you describe, and in that case, yes, the TT connections would be made to the R and W terminals there. C generally isn't used. And no, it doesn't matter which goes to which (R and W).

Tie all of the other yellow wires from the zone valves with the red wire going up to the R terminal on the thermostat. W wire from stat directly back to common on transformer. 2: Load wire from transformer directly up to R terminal on thermostat. Wire from W terminal on thermostat with one yellow wire from each zone valve all together. Other yellow wires from zone valves tied together with wire going back to common on transformer.

This way the thermostat are energized?. Or still need batteries to work?

Power will go to the stat, but you'd need a common wire to power it without the batteries.

Great video. I have a related question. I have three Honeywell zone valves with two wires going to each thermostat. I want to install a Wyze thermostat which requires a common. Luckily, I have three wires going from my thermostat to the zone valve, and the third was just tucked away. My problem is I don't know what to hook that wire to. I tried hooking it to the common which allowed the Wyze thermostat to power on, but as soon as it tried to call for heat, it would shut down. I guess this could be from the valve opening causing a voltage drop, but it happens before I even hear the relay click, which makes me think the wiring is wrong. Any ideas? In other words, how do I supply a common wire to the t-stat from a zone valve system?

It all goes back to a common terminal, typically on a transformer and in many cases multiple commons go back to the same place together. Only issue you're likely to have is that Honeywell zone valves max out a 40va transformer after 4 or 5 zone valves (about 3 taco zone valves do the same). That probably isn't going to leave enough room to power 4 Nest thermostats. You may have to add a second transformer and split the zone valves and Nests 2 and 2, instead of all 4 zones and thermostats on one.

What's the "t and t "wire from the boiler? What's the full name?

@JerseyMikeHVAC

Жыл бұрын

T just stands for "thermostat" and there are always 2 connections for a thermostat going into the boiler, hence 2 Ts. There will always be two T wires or terminals that allows a control device to turn the boiler on and off. These two Ts are opposite ends of the same circuit, which is the burner circuit. That includes all of the safeties like limit switches, spill switches, roll out switches, the gas valve, sometimes a vent damper, a spark ignition and control board, or sometimes a standing pilot with a thermocouple. But it's everything in one circuit the boiler needs to fire up. When a connection is made from one T wire or terminal to the other T wire or terminal, the circuit is complete and the boiler fires up. When that circuit is broken, the boiler shuts down. On some boilers the thermostat is hooked directly up to these T and T wires. One from the thermostats R terminal and the other from the thermostats W terminal. So the thermostat itself becomes the on/off switch for that circuit. On other boilers, such ad the type with zone valves, the thermostat only activates a motor in the zone valve, and there is a small switch inside called an "end switch" the motor activates when it is fully open. In that case the thermostat is still controlling the boiler, but not directly. The stat is just turning a motor on and off, and the motor opens and closes the end switch to turn the boiler on and off.
