Questions & Answers

My switch turns the lights on with the program but never turns the lights off. I've tried every option for lights off, but it just does not trigger the off command. How can I fix this?

Wattstopper a few questions: 1.- is the RT-200-XX available for use outdoors. What can be done to do this ( weatherproofing etc.) 2- Can it be made available for use inside a control panel. What fittings/accessories are needed to do this ?

Asked by: Mohan
The RT-200 is designed for indoor use. If you temperature outside stays within the range 32˚ to 131˚ F it is possible a waterproof box with rubber cover could be considered but it is not recommended. We are not clear what is meant by “use inside a control panel”, the switch is designed to mount in a single gang wall box.
