Heart Beat

All SpaNET spa controls feature a heartbeat LED. This heartbeat LED flashes to indicate the current health/status of the spa control. When the spa control is functioning correctly the heartbeat LED emits a single flash in a constant pulse much like a heartbeat (i.e. ON, OFF, ON, OFF etc.). If the spa control has encountered an error the heartbeat LED constantly flashes in sequence with the error number being experienced (i.e. ER-2= ON,ON; OFF; ON,ON; OFF etc.).The heartbeat LED is located on the mini-din connector end cap of the spa control as illustrated below.
