in Radiant Heating
I have replaced my thermostat with a new one and I still can't control my heat using the thermostat. I have to manually turn the CH off on the boiler itself or else the heat reaches 75 degrees in the house. Is there a way I can manually setup the heat not to exceed 70 on the boiler itself? Thanks.

    Need more info. How many zones? Circulators of zones valves? Is the a zone control panel? It more than likely is something other than the boiler.

    I have no idea how to answer your questions. Sorry I'm just not a heat person. It's radiant heating. With propane. I attached a picture incase that helps.

    The boiler will have some wiring terminals to connect a thermostat. It's possible to configure it, so that it only runs when the thermostat is calling for heat. But other configurations may not use the thermostat. Or, piping mistakes can sometimes lead to unintended flow and overheating.

    Is it possible the thermostat is only for a separate AC system?

    If it's infloor radiant, sometimes space will overheat if the water is too hot. Since there is a delay between when you start heating and when the heat leaves the slab, it's easy to overshoot if the water is too hot.

    Does the heat eventually shut off, and the space cool back down before running again? Or, does it run constantly?

    A bunch more pictures of the piping around the boiler, and any other controls or components (preferably wide angle to show how every thing is connected).

    it may be easier to tell us where you are located and have a pro stop in and setup the controls and wiring.

    I own the same boiler and use it to heat the baseboards and pex radiant heating system. The boiler has an instruction manual that you need to read and use to set up the type of heat emitters you have (Pex tubing) and you cannot exceed more than 110 F.
    Then you should be wiring the new thermostat to the thermostat terminals on the zone controller that operates the zone valves of your pex emiiter system. The zone controller will send signals to the pumps, zone valves and to the CH (heat signal) of the boiler. And the boiler will heat water to less or equal to 110 F and no more while the heat signal is active.

    I'm not sure if the OP has a zone controller. We need better pictures and more information. From the looks of it I think the boiler just does a single zone with one thermostat and takes care of domestic hot water.

    I highly doubt that the thermostat needed replacement. It sounds more like a piping issue or incorrect internal configuration.
