Study Room

Look up, there are a light bulb and a number "15" next to it, note them on the floor-plan.

There is a blackboard on the wall and a few equations on it. Thinking about substitution, which number would be which alphabet. 

Mark down the calculation result on under the number string 1~8 printed on the floor-plan for later use.

Boiler Room

One of the generators marked as "5371", referred to the blackboard in this room, the Less-and-Greater-Than Symbols shown us an order of the arrow button. As 【→】is the smallest, which should be substituted for 1. Try to form a 4 digits command.

Please refer to the floor-plan, the light bulb in this room is marked as "10". We don't know which generator carry how many volts, but there is only one line connected the light bulb to the generator marked as "5371". 

When the lights up, note the voltage of each generator on the floor-plan.

Back to the Study Room

Please refer to the floor-plan, the voltage of each generator in this room is written. To turn on the light please switch on the generators which sum as "15". 

When the lights up, note the new hint. Convert the alphabet into numbers than do the calculation, convert the calculation result back into alphabet or arrow and form a command.

 

Laboratory

Look up, there are a light bulb and a number "99" next to it, note them on the floor-plan.

Consider the lines connecting the Laboratory and Boiler Room means the generators in two room are all connected to this light bulb. To turn on the light please switch on the generators which sum as "99". 

When the lights up, beat your enemy with the command ⑤, substitute the representative button for the numbers from 1-to-8, an 8-digits command could be formed.
