Room for improvement
Transformer quality sub-par. I had a situation where there were 3 surge events and this units transformer was the only one that blew out 3 times.
I wish there was a competitor.

Works as it should
Used this to replace my original aquastat. Seems to be working fine. I'll add the schematic I used to wire my two zones except my zone valves use black wires instead of yellow but it is the same.

Customer Service 5* product 0*
I ordered this aquastat to replace on that had been in service less than a year, but the transformer failed. I installed the new one and the transformer also didn't work. I filled out the replacement form and Supply House sent the replacement no questions asked. The replacement works just fine. Obviously this is a consistent problem with the equipment from the manufacturer.

Perfect
The boiler that I was looking at had a runaway temperature occurring. And in which I did the necessary research to discover that it was the aquastat that went bad. Ordered the correct one and now works exactly like it's supposed to.

Third failure in 6 years
Unfortunately my 8184J just failed for the third tim in 6 years. Each time is the same symptom, the circulator fails to power on when heat is called. The first two failures I replaced with new units, suspecting bad solder joints. This time I discovered that the issue was the solder joints, specifically C1. I was able to re-solder C1 and return the unit service.

Not a direct replacement as advertised.
While this product can be configured to work in a number of applications. It is not a direct replacement as advertised. Knowledge beyond that provided in the instructions is required to properly configure the device for your specific application. If you are buying this thinking it will be a plug and play, you may be disappointed.

Aquastat Relay is great!
The Aquastat Relay is great, however, getting it to us was not! The system should not update at 10 PM and say the item will be received the next day. Our first item was lost, I called Customer Service on Friday and was told I had to wait 24-72 hours for the system to update. I called again on Monday when the system was still saying only the label was created for the first item. Mia was amazing, she exemplifies GREAT customer service. She stayed on the line until a solution was made. She made sure another item was shipped and we received that two days later, even though again, at 10 PM the system said we would get it the next day. It would have been much quicker to drive to pick it up than to wait a week with no heat!

Q: MY FURNACE CALLS FOR A 200 f WATER temp limit do I set the dial @200 directly pointing to 200 your instructions show setting the high limit but the instructions are not clear please explain where the pointer and the high limit water temp explain how to set the pointer and how to adjust the water temp
Asked by Ray 12 years ago

-
That dial can be as much as 20* off. Crank that room thermostat as far as it will go and using a reliable temperature analyzer, measure the temperature of the line leaving the boiler. Set the control to shut off between 180 and 200*. If you get water seeping from your relief valve, you've set it too high. Rick Chetney
