Yes, you're right Edgar - never thought of that. Like Andy I've been relying on the 'puff' sound too. From memory there is a value reset on the widgets but I have not used it yet and will have to have another look again. Of course if that can be used then we'll have to do the reset after the turbine is running. This would be the case for the RPM and/or the pump voltage alarms.
