Stromlos sind die Ventile geschlossen.
So sagt es jedenfalls Johan's Anleitung.
Zitat:
The valves are controlled via the plug on top of the unit. If +12v is applied the valve should close. So if it doesn't get 12v it's open and will allow the full coolant flow to pass. So if you unplug the control conector you will get a full flow of coolant
Zitat Ende.
Was ist nun richtig?
