Perfect replacement for SunTouch C3

Perfect replacement for our SunTouch Relay C3 that had failed after 6.5 years. They redesigned the communication wire block, making it much harder to get the wires set. That was annoying for thr install, but functionality is perfect

Avoid this item - no mechanism to control temperature

This thermostat did not have any control or mechanism to set the temperature of the heated floor system. I assumed that was basic functionality for a thermostat, but apparently I should have researched more before purchasing.
