The boiler itself is made well and would rate it 5 stars. The first computer on the boiler quit working within a week of firing it up. They did send me a new remote computer that was mounted a few feet from the boiler on the wall and has been working fine for the last couple years so I would give them 5 stars for customer service. My biggest problem with the system is there temperature probes fail if they get any moisture on/in them and they are not sealed (at lest they were not when I got mine a couple years ago). So I had to move the probe to a new location from the one on top of the boiler. I got a temperature probe fitting to put in a T mounted on the out going port on the top of the boiler. And the fire exhaust temp probe fail within a month of use I did not replace because I don't use it anyway. This all said the boiler is good, the computer seems good, however, the temperature probes are poor quality and if they don't work the computer controls are useless! Make what you will of it!

Thermostats was very easy to install. Instrucions were very clear and there are adjustments for every parameter so if you are a DIY like me you’lllove this one!

I use this a thermostat for my pool using a temperature probe. It usually works well, but sometimes if you set the temperature on the app, it reverts back to another number.

Using it as an aquastat it's doing a fine job however you should improve it by adding smart recovery
