John and I have been on site investigating the instrument air alarm at E Y, we suspect a small ice block on the blow down used for eliminating the moisture from the compressor tank. We reset the blow down after applying some heat and all seems to be working correctly now. 

We also addressed some temperature issues at E X, we turned on more heat at HC-7. 

Tuesday I will verify all heating elements are functioning on the main heater. Temperature is stable now.
