I'm not seeing much in the way of "smarts" on that board. Looking at the component side, the 3-terminal package just below the two caps on the upper right side of the board is a +12V voltage regulator (center pin is ground, bottom pin is the output). The larger rectangle halfway down on the left side of the board looks like a relay. I see what's probably a triac on the lower right side, and (perhaps) another relay near the bottom-center of the board.
I don't see anything that looks like a micro-controller. Maybe you're missing a board?
