Weil McLain Ultra 2 Temp Control

Redhawk24Redhawk24 Posts: 1Member
I'm using a Weil Mclain Ultra Series 2 boiler for my driveway melt. How do I adjust the thermostat?

After very cold nights (below 10 degrees) I have to reset my boiler. I'm afraid the glycol mix in the tubing is freezing and the boiler shows error codes. I'm hoping the solution is raising the low setting on the boiler, currently set at 38. Does this sound correct? If so, how do I do this?

thanks!

    When you say you have to reset it, do you mean the reset button on the primary at the burner?
    Or do you shut off and on the 120v power?
    What make and model burner (Beckett NX)?

    If you have to hit the reset button it means the burner failed trial for ignition and needs service from a pro.
    Hopefully it went into a 3 trial lockout.
