TO Comments	Check Mirror Condensation warning appeared around 07:57. S89-DPi got down to 1, then rose to around 1.3 for about 15 minutes as warmer, moister air moved through. Immediately closed and turned on chiller and AHUs, and after 15 minutes delta was >2. Remained closed because S89-DPe was ~0
