I added heater power by 600W at EYC 1F to increase the temp in the EYC area around 22:00.

[Kimura, Yasui, Miyoki]

We adjusted the heat generation condition in {IE}{XY}V because TMPs and dry pumps were off, and ion pumps were on at each V area.

  • IXV: Off the ceilling light, 1 FFU operation, Air conditioner off, 900W in Delonghi heater.
  • EXV: Off the ceilling light, 2 FFUs operation, Air conditioner off, 600W in Delonghi heater.
  • EYV: Off the ceilling light, 2 FFUs operation, Air conditioner off, 900W in Delonghi heater.
  • IYV: On the ceilling light, 2 FFUs operation,  Air conditioner on, 600W in Delonghi heater.

At present, I cannot know the precise temp data at IYV maybe because of no battery in the Ondotori. 

In addition, I set the target temp of the precision cooler near SR2 from 20 to 18 to compensate the heat from 7 TMPs and dry pumps operation. in the corner station. Also I turned off the ceilling light above IMC.
