We noticed that in the past there were some long lags between turning the fans on in the Laser Room and turning the two airconditioners on. This led to temperature spikes because the fans rapidly heat the room if the AC is not on. The source of the problem is that the Mitsubishi air conditioners can not be turned on by the same Unitronics control system that controls the fans and must instead be turned on at the thermostats in the Laser Room. This might be hackable, but for now, the proceedure will be to turn on the Laser Room fans at the Unitronics box in the Ante Room instead of at the Unitronix box outside the PSL. The full proceedure is attached to this log and posted at both Unitronics boxes.
