The TCS power guardian was having to consistently readjust, the tell tell sign that the calibration needs updating. I brought H1:TCS-ITMY_CO2_LASERPOWER_POWER_IN from 5.2 to 4.8 and that seemed to do the trick.

Dan put in custom mask #1 instead of the normal central heating mask, and I believe that the power monitor channel is after the mask. If this is true it would make sense that we would have to update the calibration then.
