        Comments about SetPoint 501s, One-stage SetPoint Controller with floor sensor:

        I am a professional contractor that has spent a lot of time researching different thermostats to control radiant system loops in a bathroom and kitchen set up as a heat-only, set-point, end-switch application. Please excuse the lengthy comment but I wish someone had written more than a two-sentence review to make my search easier. Tech specifications aside, even after several hours of comparing manufacturer websites (including NEST) I bought two 501s thermostats still HOPING that they would work as needed due to the lack of feedback from users in real world applications. It should be noted that the current stock picture shows the 4 button 501s which is the OLD unit and the NEW generation 501s is a much simpler 2 button shown in my posting. The wiring diagrams are also a little different than the previous generation so IF you read the Installation PDF on Uponors website before you buy (like I did), be sure you are viewing the correct one because the wiring schematics are DIFFERENT! Uponors tech line helped me avoid such a mistake. If you order this from SupplyHouse you'll be getting the current generation 2 button model, but why would you buy anywhere else anyway? I have been using Uponor radiant tubing & fittings for 20+ years & have always been impressed with the quality; this is no exception. Since the house is well insulated & air sealed, the room temp stays very stable until you shower which can spike the temp quickly & shut down the radiant if a typical room-air-sensing-thermo was used. Same for the kitchen where air temps can rise from cooking. I also wanted to keep the floor at a constant temp regardless of the air circulating from the rest of the house because the door is kept open when its not occupied. Even though it's properly ventilated, humidity can wreak havoc on the electronics inside from condensation if it was installed on the bathroom wall. In a properly designed heating system like this, you set & forget it, so I didnt need a thermostat in the room because it wasnt going to be changed once it was "dialed in". This is a slow-response system with the tubing installed as a "staple up" under the subfloor so it is very stable further eliminating the need to constantly adjust the temp setting. Plus just finding the proper place to install it in the rooms where wall space is at a premium, was extremely challenging. I just needed a way to read the floor temps ONLY (although this can be set to read BOTH room air AND/OR a sensor) making physical location of the thermo irrelevant so I could install them next to the radiant manifold in the basement without sensing the air temp where they were. Also didnt need (or want to pay for) extra functions ie. cooling, multiple temp settings, etc. In this simple application, its acting as a floor temp indicator that switches the heat on when it drops below my set temp and off when it hits my set temp (ALL settings are USER defined). The 501s was the PERFECT unit a VERY REASONABLE price. The floor sensor is super small (about the size of a BIC pen cap) so you can fit it in the grout joint of large tiles which allows you to install in an existing floor. This was set into the thinset directly under the tile during the tile job. I used a small Dremel diamond bit (shown next to the sensor) to rout a groove to fit it in the previously taped & cemented edge joint between two sheets of cement backer. I barely had to make a cut and was able to pack it in with thinset to get a good thermal contact with the subfloor. Wiring was simple with a mini screw terminal connection block: two 24V power, red & white thermo wires to the boiler control & two for the floor sensor. This has been up & running for a few weeks and its proven to work just as I needed it to. I'd also like to add that I have been buying ALL my materials from SupplyHouse since they were PexSupply and the service has ALWAYS BEEN OUTSTANDING! Ordered these at lunch on Monday, got them delivered UPS the NEXT DAY with enough time to get them installed and operating before quitting time! NO REGRETS with this purchase!

                          i had to buy model 501S with floor senser, and this option make my heating systeme work better.

                                            It does what I want it to. I have a basic 25X35 foot room that has a suspended concrete slab with 3 circuits of tubing. I just wanted something that senses floor temperature and will maintain the floor temp. I dont need it to sense room temp (although it can) because the radiant is a secondary heat source to my hot air. I use it just to take the chill off the floor.

                                                      Assuming concrete floors, you drill a hole for the sensor and stick it in. A heat conducting compound of some kind in with it will make it more responsive.

                                                      Thats what mine does. Its nice because you can set it up to maintain a set air temperature or use the probe to maintain a set floor temperature. Using the probe to maintain a set floor temperature is what I do. You want to keep the slab steady instead of hot to cold all the time. Its a good controller and has all the functions you will need.

                                                      You can. You will just need to wire the circulator and thermostat to a proper control.
