Two-Speed Pump Setup
A common configuration question: two-speed pumps require proper relay setup:
- First relay: Turns pump on/off (controlled by pool/spa circuits)
- Second relay: Switches between low and high speed
- Default is low speed; configured circuits trigger high speed
- EasyTouch 8 supports up to 7 high-speed trigger circuits
- EasyTouch 4 supports up to 3 high-speed trigger circuits
Maximum Programs
EasyTouch has a 12 program limit. If you see "Maximum Programs Exceeded" in the Schedules menu, delete unused programs before creating new ones.
