I want to use a Shelly 2.5 to control the speed of my ventilation system in my home.
At the moment I have a button with three positions; low, medium and high. But actually only two signals are sent to the system; medium and high. So actually the control is the same as with a roller shutter. The up and down signals go to the motor. In the neutral position, no signal goes to the motor.
So I think I can use a Shelly 2.5 to take over the control from this three position switch.
My only question is if I can disable the "OPEN/CLOSE WORKING TIME", for example by setting this time to zero.
Does anyone have experience with disabling this working time?
