System 2000 Question

    I recently had the hot water control for my System 2000 configured directly off the boiler rather than through the domestic side of the Heat Exchanger. Now the system will sometimes lock up when hot water and one or two of my two zones are calling for heat. I have to reset after 20 minutes or so and all is fine. How do I correct this problem? Error code is 140 degrees flashing.

    You'd be better off starting your own thread (click on the pencil) but that would point towards a burner issue rather than a zone issue. 
    The water heater isn't using the plate heat exchanger?

    Thank you for your question, @StephenReardon .  
    The 140 flashing light means that the boiler did not heat up as quickly as the energy manager would expect. In your case, that may mean that the hot water tank is not piped properly or that it is not wired to the manager properly (if the burner is not locked out).  The thermostat on the tank should be wired to the same thermostat (T) number as the zone valve (Z) number that supplies boiler water to your hot water tank coil (if that’s what you have). 
    You’re a heating professional should be able to clear this up quickly. Some more details here will help us figure out what you have.
