The Thermal Monitor helps monitor the temperature of a Nuclear Reactor. To open the GUI, right click the Thermal Monitor. Use the slider to select the maximum safe temperature of your nuclear reactor. If the reactor reaches that temperature, the Thermal Monitor's screen changes color to red and emits a redstone signal. The redstone signal can be sent to an alarm or directed back at the Nuclear Reactor, which would cause the reactor to shut down.

The temperature can be set between 0 and 15000 in intervals of 100. Right clicking the Thermal Monitor while sneaking will not open the GUI. The temperature chosen should be lower than the critical temperature of your reactor. If a reactor heats up extremely quickly, the thermal monitor may not have enough time to emit its redstone signal before the reactor explodes.

The Thermal Monitor should be placed within one block of your Nuclear Reactor / Reactor Chamber or, preferably, directly on it. When searching for a reactor, it only checks one block in each direction. If multiple reactors are placed near Thermal Monitor, then only the first one it finds will be monitored.

The Thermal Monitor has three indicator colors:

  • gray - no reactor found, detach it and move it closer or place it directly on the reactor chamber
  • green - actively monitoring a reactor, and the reactor is below the selected temperature limit
  • red - actively monitoring a reactor, and the reactor temperature has exceeded the chosen limit

An improvement to this monitor can be the Remote Thermal Monitor as it enables remote monitoring of the temperatures of the Reactor Chamber.
