Thermal Monitor

Thermal Monitor is a block added by IC2 Nuclear Control. It measures the heat level of the Nuclear Reactor next to or on it. If the reactor reaches a specific heat level, the Thermal Monitor changes color of it's indicator to red and emits a positive redstone signal. Right clicking the block will open the GUI. Any temperature in the range 0-15000 with step 100 can be set within this GUI.

The Thermal Monitor should be placed either directly on the reactor/reactor chamber or on any block near it. When searching for reactor, it checks only one block in each direction.

The Thermal Monitor has three indication colors:
 * Gray : The reactor isn’t found.
 * Green : The reactor is cool.
 * Red : The reactor is hot and could suffer a meltdown.
