- Sequenced Sprinkler Control -
Provide sequenced
on and off control for
multiple sprinkler
valves.
Pressing the keypad F1 button will activate a Chain Channel that will cause sprinkler
valve 1 to turn on for 15 minutes (programmable) and then turn off. At this time, sprinkler
valve 2 will turn on for 15 minutes and then turn off. Then sprinkler valve 3, sprinkler valve
4, etc. will repeat the on/off cycle.
1) Press F1 to activate Chain Channel 5.
2) Chain Channel sequence activates all relays starting with Relay 1 for 15 minutes, Relay 2
for 30 minutes, etc.
3) Relay 1 switches power to NO to activiate valve 1, thus breaking power to following
relays / valves.
4) Relay 1 is restored after 15 minutes reconnecting power to relay 2 for the remainder of
its countdown time (15 minutes).
5) Relay 2 then restores to energize Relay 3 for the remainder of its countdown time (15
minutes).
Note: This sequence passes power when relays restore to
normally closed (NC) via the jumpers.
