How to control a Ca reactor w/ RKL?

[orthokardia]

I have a RKL with the SL1 expansion. Does anyone know how to use it to control a Ca reactor? It appears the SL1 has low lover signal outs that might drive a relay, but i do not want to do electrical DIY around saltwater.

thx - bart

Not sure what you mean Bart? To control a Ca Reactor you would use a PH probe to control a solenoid. The solenoid is just plugged into standard power outlet on the power bar.

Yep... those are actually low level inputs on the SL1. The only module that has relays is the SW5 module.
