There is the potential for a warranty issue A distributor who is not authorized to distribute the product. As a result of an error code on my boiler's aquastat that I was able to clear with this part, I bought this. Because I anticipated a failure, I bought this product to have on hand as a backup replacement In the end, it failed, and I replaced it with this part. (Note There were no differences in part numbers between the Aquastats involved, which were all Honeywell). For 8 days, it worked fine following a simple procedure. In the end, it failed as well. In my contact with the seller, he informed me of a 30-day return policy. By the time I needed it, I was several months beyond the deadline and had left the item on the shelf. I should contact the manufacturer, he said. I can't get back those three hours of my life, but Honeywell went well with the part with the following caveat. This was a one-off Once was a goodwill gesture, but they won't do that It was explained to me that the part comes with a three-year warranty, but it is only valid if the part is purchased from an authorized Honeywell distributor, and that seller is NOT an authorized Honeywell distributor. To cut a long story short- A good product, a good price, but make sure you install it immediately upon purchase so if it fails, you can have it replaced under the exchange policy of the seller. You're on your own if the program fails after 30 days. An MSRP of $315 is listed on the item, but the cost to contractors is approximately.
(FULL UPDATE) This had been in operation for about 3 years. The installation took place in January of this year, 5 months ago. We had a great experience with the boiler into April, and then the boiler was serviced We brought the boiler back in service on yesterday, 09/30/2015, and the Aquastat failed (Err 3) to do so. An example of a hardware failure is the control with a new one. It was used for only three months with conditions that are far above what would be considered suitable for this device. I have been with the company for five Since I had to research beyond the purchase phase of the purchase and into the review and troubleshooting phase of the purchase, I had to speak to other people who had had this model and had the same problem. It was the choice to replace our older model and compatible at the time, but time will tell and the follow up response to me is just as important as it was at the time. As for Amazon, we will have to see if they return the department. It is up to either the Technical Department or the Warranty Department to resolve the problem. Honeywell's Technical Department may back the product. This also turned out to be a waste of time. I hope this is helpful to someone. This was the place where the product was purchased! Once I learn what the outcome of my contact with Amazon is, I will follow up with them. I consider this unit to be very good (first review purchase). An older model of the device failed to work. pulled the quick connections off and bent the card holders, removed the old electronic card, and then reconnected the leads. I simply bent the card holders back to their original positions and inserted the new electronic card. I like it very much. You can check the models this unit will replace by visiting this website.

I had a failure of my old aquastat's circulator control relay and my old lubricator had begun to leak The room was heated by fired baseboard radiators via convection only with a very slow rate of heating.
These controls do not pose any problems. It seems to work. This control was installed in place of a beckett control. The construction is solid. A price that is very good.
There was a problem with this product - it burned out right away Having to hire someone to come and replace it was not an option. Spent a lot of money on this.
You can adjust many settings on this unit to fit your needs. As far as I'm concerned, the default factory settings are just fine. This way, it can be put to use nearly immediately Transferring the wiring is all there is to it. I have had it for one year and it has been working well. I would like to have separate heating zones. As far as I am concerned, I am happy with my.
The equipment I ordered is back with me. Once again, everything is running smoothly.
