Test mode screen

Hi guys. I’ve managed to set my v3 up perfectly using the install guide. Only issue I am finding is that when in the test screen I can manually turn on all outputs apart from one which is the second from the left ( actuator 2 which I will use for heating ). I have tried calibrating the touch screen and loosening the screws of the case but it is still non responsive. Has anyone else had this issue? I will be brewing over Christmas so would like to get everything operational ASAP.
Thanks and merry Christmas

My guess is that you already have already configured some devices in device manager and the PID/PWM is driving the output.

So when you change it with the touch screen, it is immediately toggled again by the temperature control.
