Note: Zonecheck key switch features a time out function in Self Test mode that
allows the user to start the flow switch test which will end automatically after
two minutes. The waterflow detector will be activated during the 2 minute
timeframe, upon activation the waterflow detection LED on the zonecheck
key switch will turn on and remain that way until the key is returned to the
standby position.
