Re: McQuay WHS 248.2 water flow
Hi,
The following is an extract from a document that I have
When the unit starts, there has to be 20 sec of flow during the first 30 sec of pump operation. When the unit is running, the flow switch has to be open for 5 sec before the unit trips in flow alarm
Perhaps it's a timer?
