Switching up the dials

This is a confusing panel to look at, so let’s quickly dissect it.

In the top left you have numerous lights with symbols on them. The lights tell you whether you need more or less of a concentration of CO2, Gas, or O2. Your job here is to balance the input of gasses into the incinerator to make it safe to open the door.

There are two lights for each element, each to tell you if you need more or less of it. Three lights, one for each element, will be lit up every time you play around with the dials.

Along the bottom are the dials for the Co2, Gas, and O2. You will be rotating these in response to the demands of the incinerator.

In the top right is the screen. This serves little practicality, only showing you how close you are every time you hit the lever.

When you think you have the right combination, the lever, on the very right, will have to be pulled. Upon the lever being pulled, either the door will open, or the lights will show you whether you need more or less of an element. If you have the right balance, then neither of that element’s lights will show.

So, essentially, if an element is showing you that you need more of it, find that element’s dial and move it anti-clockwise. If you need less of it, move the dial clockwise. Only do small movements of each dial and then press the lever. You may have to repeat that process a few times, but you’ll soon have the correct balance.
