Signal from the remote sensor can be receive a signal up to 8 blocks in each direction from the reactor. To increase range - use the Range Upgrade item. As an additional feature, this machine shows a progress bar of reactor heating (100% is the signal level it must be set to). You can adjust the facing side of the indicator with a Wrench. When the machine does not have enough power, an indicator bar has a dark gray color. It also indicates if a reactor can't be found or is too far with a bluish gray color.
Sneaking+Right Clicking with a wrench allows you to rotate the Remote Thermal Monitor around an axis.
The Monitor will output a redstone signal if the given temperature is reached, making it a very good way to control a Nuclear Reactor temperature.
It will use 1 EU/t. Energy consumption can be increased via RemoteThermalMonitorEnergyConsumption config parameter. The default energy storage is 600 EU, and the max packet size before explosion is 32 EU. Energy storage and max packet size can be increased with energy storage and transformer upgrades.
Power can be supplied via wires or with energy storage items (battery, energy crystal etc).
