Question
my system has two kd6 controllers.  One for the front yard and one for the back as it is a 1/2 acre lot.   The back yard controller works fine but the front controller will not activate.
The controller is on and the dial works and all the functions work but it just will not activate for some reason.  i have tried to manually start each zone but none of them will work.
Any help you can provide is greatly appreciated.

Answer
Hi Mark,


Make sure the sensor SW is not in active position unless you have a rain sensor.
Make sure the common wire, white, in connected to all valves.
Make sure the water supply is open.
Last resort: reset the controller, put an small flat screwdriver in the reset contacts,  the display will blink and the controller will be reset to the default program.

Regards
Guillermo
