Post power glitch, ETMY ring heater was on with 0.55 W top and bottom. DIAG_MAIN reported that this is nominally OFF, and trends for the past few days agreed. I brought these back to 0 and double checked the others as well.

The ITM ring heaters were not checked in DIAG_MAIN so I added them. As of right now it will check if they are off or on (not for specific values), if only one half is on, and if the top and bottom differ by some threshold percentage. I'd like to add checks to make sure that they are at their correct values as well, once that seems to be in a stable state.
