Following the similar test we did yesterday (August 2nd - WEB AHU selective switch off), this afternoon we performed a switch-off test of the North end air conditioning system. Below, the time of each action and device are reported:

14:15 UTC -  AHU OFF + cold and hot water pumps ON,  T = 22.0 degC

14:38 UTC - cold and hot water pumps OFF (simultaneously) +  AHU OFF

15:00 UTC - hot water pump ON + cold water pump OFF+ AHU OFF

15:11 UTC - both water pumps ON + and AHU ON, T=23.6 degC

The analysis will follow.
