This morning, after the power glitch, I went out to check the settings for the analog communication voltage scaling for the TCS chillers. For both TCSX and TCSY chillers: High Volts: 10.0 Low Volts: 0.0 High Temp: 40.0 Low Temp: 5.0 These are the same as the defaults listed on page D-5 of the Thermo Scientfific ThermoFlex Recirculating Chillers (Deluxe Controller) manual (P/N U00939, Rev. 08/14/2014).
The analogue input voltages were never changed from the factory settings. The settings that were changed were the fault and warning settings for high and low temps. These should have remained after power cycling the chillers though.
