I have a Jandy 6613 power control panel for my pool equipment. It is the model RS6, which can support 6 different relay control circuits. It was installed with only 5 relays, which are all being used for various pool equipment. The location where the 6th relay would go is empty. I want to order a relay to install in that position so I can use it to control my yard lighting. I am an electrical engineer with a lot of wiring experience, so I'm not worried about how to do it. What I need is info on where and how I can order a relay. I don't have a part number for it. If anyone can direct me to a site where I could order this, I'd appreciate it.
