Rieco Titan 36013 Receiver / Transmitter 4-Function Control Kit
The good folks at Rieco Titan walked me through troubleshooting steps to isolate my failure to a defective controller. Installation was straight forward. I hope I never need the emergency remote, but it's comforting to have. Worked without a hitch.
Works great, replaced an existing unit that failed. We love being able to walk around the camper and raise or lower all the legs at once!
