Here's another device in dormitory, which is the floor heating controller. Floor heating is very common in Korea, and the only option of heating in dormitory, since the management forbid the use of heating mode of air conditioner. The controller shown in previous post for room air conditioner is only useful if the central controller is enabled. Also I was told during summer, they might just turn off the cooling in the afternoon to save on energy as they presume you are in campus.
