The AC unit in the H1 diode room has been cycling off an on about every 50 minutes resulting in a 5 degree temperature swing in the room, from 70 F to 65 F. This may be due to the system being underloaded, and the minimum amount of cooling the unit can supply is pushing the room to 65 F before it turns back off. This unit ties into the AC units in the H1 electronics room, half of which happened to be off. Yesterday Richard brought them back up, and this appears to have created enough of a load on the system to keep the diode room a little more stable, but it still is experiencing temperature swings.
