Good idea, another control item that is off-board and therefore easier to interfere with. But I think it'd be easier to use an electronic, rather than mechanical, solution to simulate the low water level. If you learn what the critical timing is, you could even program in a brief "reset" within that window to prevent the full shutdown.A second option could be to install a linkage to push down on the level sensor float, triggering a low-water shutdown, which should allow a restart when the float was released. But that might be defeated if the timed shut-off due to low water is exceeded. I saw no indication of how long that time interval is. So you will need to discover that.
