Trinity boiler error code
I have an NTI Trinity T200 boiler for my radiant heat. The panel is showing ER4. This seemingly happens when the boiler tries to fire, especially when I'm asking for a little heat (like 72 when the house is 69). Recently I replaced the boiler cover, gasket, and two insulation disks.
ER4 says "Unit has been running for 1 hour without reaching 80 of its set point"
80 what? Percent? Degrees? Some research on,one makes me think it may be a gas pressure issue? This thing had given me issues since I bought the house. It was installed by the previous owners son so...
Any advice is appreciated, especially if it's a free or cheap fix.
