Smartzone-2x 2 Zone HVAC Controller Kit W/ Temp Sensor Dual Climate Control T

Good replacemnt for old XCI board.

I replaced an XCI board that had been there 15 years. (It had been flaky, e.g. removing the thermal sensor did NOT disable the zone motors, before it started tripping the 24 volt transformer.) I chose this board because it looks like the original XCI board.

It was easy to install and works well. I appreciate the lights which indicate what is going on. For example, I can see which thermostat is driving the board and what function is being called for as well as which zone is being closed. I also appreciate that it has a fuse, given that the old board did not.Read full review
