1013-200 boiler control

R_L_SR_L_S Member Posts: 1
1013-200 boiler control. Has a green light and won't do anything. The control is 2 years old I have 2 separate boilers
Changed a few things and can not get this to work. Any ideas would be helpful. Thank you

    Steady power green light? No other flashing lights?
    Try jumping the 2 black wires that the thermostat wires are connected to. Check all molex plugs are secure in the module.

    What is the make of equipment this is on? I assume you have no heat is that correct? Is the GREEN light steady? The green light on steady indicates there is no call for heat as was already offered try jumping out the thermostat connection.

    this is a popular control used on Weil McLain gas boilers.
    on page 71 and 72 of this manual are the trouble shooting diagrams and procedures

    there may be a sensor that fell off the piping or the thermostat is not calling or a wire is open (not shorted). It can get involved or it can be very simple. See if the book helps
