Sun CP1 Fill, 10:00 fill did not run, manually ran a fill at 10:50
Regularly scheduled fill at 10:00 did not run because both thermocouples were above the +30C nominal max limit [31C, 34C] presumably due to icing around the TC and/or Ref Junction.
Sun Jan 11 10:00:00 2026 ALARM: Abort run, Both Thermocouples BAD
I made a temporary change to the configuration to increase the nonimal TC-MAX to +40C and scheduled at 10:50 run.

This appears to be a good fill. The settings will be restored to nominal for tomorrow's fill.
