[Question] Nuclear Reactor heat display

So, I'm building a nuclear reactor security system with tekkit and because I'm not that good at coding I wanted to know how to make a heat display.
Like: there's a big monitor on the wall and the computer prints the reactor temperature on the monitor (I've got nuclear control heat sensors wired to a bundled cable) so it has to be a program wich prints something on a monitor when it gets a certain input from a colored wire.
Edit: sorry for posting twice, not really familiar with this forum :/

The Industrial-Craft Reactor changes the effects due to max heat. And a chamber adds 1000 more heat tolerance. How many chambers would you normally have"?

I have 5 chambers but I've already wired an alarm to a thermal monitor wich is set to 7000. So when the reactor reaches a heat of 7000, it will send out a redstone signal into a bundled cable and the computer has to detect the input from for example the red cable inside the bundled cable and print 7000 on the monitor (and if it's possible it has to print the number big).
