The wall unit is the transmitter which sends the signal to the receiver that is wired to the stove. The transmitter sends the signal and the receiver powers the internal contacts to turn on the stove. Basicly only used power during switching the contacts on or off. Yes it does use some power "listening" for the signal but the main power draw is during switching.

Okay that's what I thought. When you said the "batteries aren’t using power all the time just during turn on or turn off switching" I thought you might have discovered something new. Still don't know why it's worth going battery powered when they're just another point of independent failure in the circuit. (As an electrical engineer we try to eliminate unecessary points of failure.) But, whatever floats your boat I guess.
