When the controller is activated by either “Auto” programming or a “Manual” Input, the
power and an encoded signal is supplied to the Line Out Terminals.
The Decoder operates as an electronically controlled switch. When the decoder recog
nizes the encoded signal that matches its programmed data, it then allows or “switches”
power to the solenoid on the valve.
