PSL set to Science Mode
More info / changes needed to find an AC-ON-all-the-time stable temperature for the PSL.
Temperature range of the table sensors change with changes to the makeup air.
| commissioning, 100% makeup air | N: 72.6F to 73.9F | S: 67.7F to 69.5F | delta N: 1.3F | delta S: 1.8F |
| commissioning, 40% makeup air | N: 71.5F to 75.1F | S: 69.4F to 72.3F | delta N: 3.6F | delta S: 2.9F |
There's a way to see/set the temperatures that controls the AC unit coming on and turning off, and with the table temperature range changing with makeup air, I suspect these AC on/off temperatures are either not set or set to a wide range, and this could be a place where a change may allow for more PSL cooling options.
