Rinnai 1004 heats to a temp 4 degrees higher than set temp. It seems to be consistent. Can I adjust or calibrate the set or the temp reading with a screw adjustment or othewise?
You can adjust the position of the room air sensor found on the back of the unit between the heater and the wall. It is a black rubber bulb with yellow wires. There is a few inches of extra wire you can extend higher to get a more accurate reading of room air. While you are back there, check for drafts that will give you false readings.
My Rinnai keeps the room 14 degrees higher than the setting.
we keep it set on 60 and the room stays at 74. We'd like the room to be 68-70, but 60 is the lowest setting on the heater.
I don't think our model has the external room sensor, so I don't know what to do.

My Rinnai 1004 heats to a temp four degrees higher than what we set it at, consistently. We should be able to adjust this. Where is adjustment and how can I adjust?
I'm trying to remove the front panel (cleaning out the dust) but there's a grill screw that is too stubborn to remove. I'm afraid if I use brute force I will damage it. Are some screws special that only screw half way ? It seems like something is attached behind it.
