Pentair IntelliTouch personality kits can turn your lights on and off, if you are looking to dim them you need the IntelliTouch Controller Dimmer Module. One module can support multiple lights from 100 watts up to a combined load of 1,000 watts using 120VAC. The module installs in a relay location in your power/load center. Up to 10 dimmer modules can be installed in a system with a maximum combined sysem load up to 4,000 watts. Expansion kits (i5X o i10X) may be needed to house multiple dimmer modules. IntelliTouch Controller Dimmer Module is designed to be used with pool and spa lights only, not backyard lighting systems.
