Do you sell an option to the C1900 that includes a control unit.

Yes - See the C2000. It includes a a control unit. You will still need equipment to dispense the chlorine nad acid.

Is the Jandy C1900 a stand alone unit or what other equipment is required with it

A     Answered on 1/24/2012 by InyoPools Product Specialist Patrick P.

No, the Jandy C1900 only monitors the levels of Chlorine and pH in your pool. It needs to be linked up with a control unit like a Jandy Aqualink to determine what to do when the levels are out of programmed limits. Also tanks like the Stenner Feed Pump and Tank System are required to hold and dispense the chlorine or acid when required. Or if you don't want to use liquid chlorine, you have the option of generating chlorine with a Salt Chlorine Generator like the Nature2 Fusion Salt Chlorine and Mineral Dispenser.
