Description for Honeywell-Sparco AM100R-US-1

The Honeywell AM-1 series accurately adjusts, maintains and limits the hot water temperature to a desired setting selected by the user. In domestic water applications it offers scalding protection and bacteria growth control. By installing a Honeywell AM-1 mixing valve and raising water heater storage temperature setting and limiting mixed outlet water temperature to safe temperature more usable hot water is available. In heating applications it provides comfort and protects the equipment.

                    I put this in to temper the hot water going to my radiant floor heat. The kitchen is radiant but the rest of the house is baseboard heat. I had a DDC control system in for the last 10 years with a modulating ball valve doing the job but now that I am selling my house, I had to "bumb it down". As it turns out, I probably could have used this in the first place while only sacrificing the ability to reset the water supply temp setpoint. I would use it again if needed. It responds quickly and seems to hold setpoint well even with changing entering hot water temps.

                          THESE ARE GREAT FOR RADIANT FLOOR AND HEATING UNITS
                          SWEAT CONNECTIONS ELIMINATES MALE ADAPTORS. RECOMMEND PLACING A DIAL THERMOMETER IN A TEE AFTER THE UNIT TO MAKE IT EASIER TO CHECK WATER TEMP.

                                      This valve was exactly what we needed to fix our hydronic system. It's a good quality at a great price. We checked around and this was the best deal. We also received it quickly.

                                                  Just a heads up, the item that they shipped is not the same as the item pictured, the flanges are different, they're larger. The item shipped is even different than what's on the manufacturers website. See attached photo.

                                                        About eight years ago I installed an AM-1 mixing valve in my home's radiant floor heating system (after a competitive valve's failure), and it has worked flawlessly since then, holds temperature well. Also installed one in my daughter's system five years ago with the same result. Excellent product, highly recommended.

                                                                I have one of these feeding a radiant floor loop - but despite having primary loop temp of 170 or so, the most this seems to kick out is about 100. However, I am speculating that my flow rate is not adequate (1 3/8" pex loop). I don't know what that flow rate is. I have two other valves on air handlers where they appear to work just fine.

                                                                  1. Look for obstructions, debris in the line. The opening is

                                                                  and loop temp.

                                                                  3. Do you have a Y-strainer, is it clean. Do not rely on just opening
                                                                  up the drain on the bottom, the screen could be clogged and not allow flow
                                                                  past.

                                                                Q:

                                                                Would this work for DHW or is it just used for radiant flooring? If not what's the difference between the valves for DHW and radiant mixing valves?

                                                                  Mixing valves that are designed for heating systems generally have higher temperature ranges than ones designed for domestic hot water plumbing. Since heating mixing valves also do not carry the necessary approval codes for use with potable water, we would not recommend using them in such applications.
