I use this one with my mag stoker. I like the digital readout and setpoint.

Titliest, is this a simple two-wire hookup?

Yes its a two wire. Under the cover, mine is aaa battery powered. The wires land on the B and W terminals. I have the slider switch on gas/oil setting instead of the heat pump setting.
