    3-wire surface aquastat cross

    I'm looking to cross what looks to be a Minneapolis-Honeywell 3-wire surface aquastat.  Label plate says : L109A1X1, also says use on Series 10 controls only.  Any ideas on what else I could use ???

    thanks,

    Is this on an

    existing series 10 system? What are the other controls? Typically you can drop the red wire and use an L4006A provided the bulbfits in the well if a well is being used. Just wire the white wire to one side and the blue to the other side of the switch.
