Cold loop lowered for NE & WE

Yesterday morning in order to optimize the working point of the air conditioning in the terminal halls we have lowered (as suggested by Davide) the temperature of the cold loop by acting directly on the Eurotherms; the DMS alarm thresholds has been adjusted by the operator, below in detail:

9:30 LT -> WE cold loop from 14 C to 13 C
9:55 LT -> NE cold loop from 13,5 C to 13 C

This morning we deacrised again the working point:

9:52 LT -> NE cold loop from 13 C to 12,5 C
10:40 LT -> WE cold loop from 13 C to 12,5 C

At 12:50 LT we restored 13 C for the NE because the temperature of the water prevent the right functioning of the machine around this working point, more investigation will be done soon.
