Review: Replacement for failed OJ Microline radiant floor heating thermostat. - This Radiant Floor Touch Screen Programmable Thermostat with GFCI, Includes Floor Sensor Model # UDG4-4999 was easily installed to replace the failed OJ Microline thermostat (10+ years old). I didn't even have to remove the under ceramic tile sensor (it was supposed to be installed in a plastic tube but I'd hate to have to find out!), just unhook the six wires (two load, two line, and two sensor) and hook them up to the new thermostat. The new touch screen thermostat is intuitively easy to program as well, and you can calibrate it to the actual floor temperature. I used an infrared thermometer and adjusted the wall thermostat to read the same as the floor surface temperature.
Review: Easy to use! - We had a professional installer do the work. It was easy to install and the touch screen was easy to program. It has been working well for a few days no problems and it has worked flawlessly. Very happy.. Bill

## Questions & Answers

**Q: What is the distribution Id?**
A: The distribution ID is 11151

**Q: If there is a power outage will the clock reset automatically or have battery backup for the outage**
A: This unit design does not have a battery backup or has auto clock reset. When ever there is eletric current disruption, you must manually reset your clock, date, and day.

**Q: Does the screen backlight turn off automatically or is it always on?**
A: turns off automatically

**Q: I need a controller that switches 120v on when remote sensor a is < builtin sensor b, and sensor b > 70 degrees.  can this unit do it?**
A: No, I'm afraid this thermostat can't do the required task. You can either set remote (floor) sensor temperature settings or built-in (ambient) temp. settings. As soon as measured temp. on sensor that is set to be in control (floor or ambient mode) drops below settings, the controller will switch 120V or 240V on.

### ⭐⭐⭐⭐ Excellent upgrade, some unexpected, undocumented installation issues
*by M***R on November 8, 2020*

The previous owners of our house had radiant heating installed underneath tile in one section of one floor. The system is well over 10 years old, and the legacy thermostat was a major pain to use and not intuitive at all. I had long wanted to replace the existing thermostat and was keeping an eye on this unit. Surprisingly, it was over $50 cheaper here on Amazon than on the OEM website, so I jumped on it. The unit itself is well made, and the OEM has videos posted on their site that explains the upgrade process which SEEMED very easy/straightforward. Since the legacy installed floor is 10+ years old and from a previous owner's tenure, we had zero documentation on the system. The only fly in the ointment came during setup after I had physically installed the unit. First, the programmer asks for the maximum power output for the floor. I wasn't anticipating this data requirement, and after some research it APPEARS the OEM limits the floor mats to 1800W on 120V, so that's the value I entered. Second, the system wants the resistance of the temperature probe. It comes with one, but I was wiring into the existing, legacy probe. Again, there is zero documentation to go on, but went with the default 10 ohm setting. Couldn't even find the probe specs on the OEM website. I guess I chose well, because the system is working flawlessly at the moment. Programming is now a breeze, changing settings (for travel, etc.), and monitoring energy usage is simple and very straightforward. I am VERY happy with the upgrade. I did not opt for the WiFi-enabled unit, since it's such a small area of the house and the utility of this function would be extremely limited, not worth the upcharge. Hopefully, this unit will outlast our tenure in this house.
