After years of having two tankless water heaters and one hardly ever working, I decided to purchase a kit to get them to sync. I installed it and nothing changed. I revisited the issue several months later and discovered that the instructions called for different cables than were contained within the kit. I looked on line for them and only Supply House had them. I ordered them and they came quickly. I installed them and now have both water heater working in synch with each other.
