Question
Station 4 does not turn off until Station 5 turns off.  This affects the water pressure in Station 5 and makes irrigation inefficient.  Is there an adjustment on the controller that will make turn off of Station 4 consistent?

Answer
Hi Ron

Measure the volts at port 4 when station 5 is watering, put the red lead to the port 4 and the black lead to the common port, if you get about 24V the port is damaged. If no volts are present the problem is at the valve. Replace the selenoid and or the valve.
