boilermate 2000 smartcontrol shot - need quick fix

hello - we have a amtrol boilermate 2000, the smartboard is shot, would like to know how i can wire the aquastat and eliminate the smartboard on the boilermate as a quick fix till new smartboard gets delivered - thanks

ECT contols and Johnson controls both make electronic aquastats with a temperature range that you need. removing the old probe is the hard part because you need to drain and tip the tank over to do it. Once installed you can pretty much cancel the new board as either one of those controls will do the same thing just fine.
