We now have two temperature controllers in the lab:
A couple of weeks ago they installed a second temperature controller on the South Wall. This drives the HVAC heater that is above the stereo.
The original temperature controller (West Wall) was also upgraded to have a fancy new 1960's-style mechanical display of the setpoint-needle on the front type. Maybe in 50 or 60 years we can get a digital controller in here.
At the moment the second controller has not been calibrated to match the original controller.
