This design has two valves and two dials with hands.
Players need to rotate the valves so that the hands on the dial remain in the green range. This is not easy, as both valves are calibrated for different speeds, so this task requires teamwork and a sense of tact. If you keep the speed on the fans constant and the arrows are in the green ranges, the cache on the actuator will start to rise at the top.
This puzzle can be changed and reprogrammed based on your task. Possible to open magnetic locks, activate another puzzle, play music, turn the light on/off. Just let us know about it to calculate additional functions.
