LAARS Endurance problem

I have two LAARS Edunrance which were installed 6 years ago. Recently I turn down the temperature, the pipe is still warm. I mean I set the the temperature that is much lower than the room temperature, the heat is still on not sure what's going on. i feel i am wasting my money on the heat,



My second Edurance has the opposite problem , it has hot water but no matter how high the temperature i set , there is no heat or a little warm.



so i hope somebody can help, i am really sick of LAARS.

    How are you adjusting the temp?

    How are the 2 boilers controlled?

    Turning down the temp on a non-condensing boiler can damage the boiler.

    Can you post some pictures?

    These two boilders are working independently, i turn down the tempature with thermostar. since recentely the weather is quite warm so i set down the tempature on the thermostar, but the heat is coming . I have the two LAARS with the blue pannel.



    maybe the anti condensing valve in the second boiler is not working. thx

    Thermostar?

    Are you turning down the thermostat in the house or something on the boiler?

    Does the boiler also heat the domestic hot water?

    Picture?

    Zone Valve

    In the Laars there is a Honeywell zone valve that opens and closes on heat demand. At times those go bad and allow the heat to go through all the time slowly or fail the other way and dont open allowing no heat I would check there first.
