What pressure are you seeing on the gauge?
Ok is your aquastat turning the unit off at the correct temp..do you know how to look at that?
OK then shut the feed line off to the coil does the pressure still continue to rise or stop and not blow off the relief?
OK with the coil water feed off the pressure is still rising? If so the aquastat is bad. Nothing else would cause this issue.

I did not have the model unit, if the pressure continues to rise it must be heating as it can not just rise on its own can you set the Aquastat down?
OK so the pressure continues to rise without it heating and with the feed shut off right?
