              This control is essentially "bulletproof" and far more accurate to set for precision temp. control.

              It also is expandable for Outdoor reset and hot water control.

              This control is full featured with multiple ways to set it for the installation at hand. A truly universal replacement control with Honeywell quality and reliability. Have never had an issue after installation upwards of 30 units now and counting.

              Honeywell has a winner here.

                          aquastat works perfect, but did not fix the small problem with my boiler, wrong guess on my part, nothing wrong with the aquastat though.
                          but even more important was dealing with Pexsupply. As a new customer and a very suspicious one at that EVERYTHING they said about the order, process time, delivery time an complete handling of the order was right to a (T). I was really surprised an satisfied with the complete process. so to make a long story short, Pexsupply has me hooked. and I would STRONGLY recommend this company to do business with !!!

                                This aquastat did exectly as it was supposed to as soon as I powered up the system. It is a one device unit that installed with a screwdriver, was easy to wire and is able to control one complete zone and the burner. It also wired easily to an existing 2nd zone relay made by another manufactured.

                                      I purchased this aquastat about a month ago.
                                      Delivery was fast and the aquastat works well.
                                      In my case I have an older boiler and had to purchase a burner primary control box as well because the aquastat does not have terminals for the CAD cell. So if you are upgrading an older boiler keep that in mind.

                                      I'm very happy with this unit so far.

                                                        Easy install on 30 year old water boiler. I like the fact that this is electronic, has it's own built-in fault codes: if something malfunctions, just check the digital readout, and refer to the chark in the service/owners manual. Fully adgustable, with "cold water" start, if you don't have the tankless domestic hot water option.

                                                              Installed on my new Biasi B3 oil boiler with Riello R40 burner. Install was easy. I did have to purchase the extended length temp probe as the Biasi's temperature well is located in the back of the boiler. I have the aquastat wired into a two zone system and also with a Beckett heat manager.
