Great thermostat for the price

Pay attention to the ISU settings on installation. It would be better if auto mode was enabled by default.

Replacement for LUX TX500

Thermostat replaced my LUX TX500 perfectly. Installation was easy and took very little time and effort.

5 out of 5 stars review

Works great with high efficiency hot water heat

Using this for 2 years on my main heating zone and like it. I have it set for different temps for weekdays vs weekends (5-2), and a couple degrees cooler at night. It has learned to bring the boiler on about a half hour before returning to my higher morning temp. When we go away for a longer period like a vacation, it's easy to set it to hold a lower permanent temp.
