  The RENO experiment has been in operation since August 2011 to measure
reactor antineutrino disappearance using identical near and far detectors. For
accurate measurements of neutrino mixing parameters and efficient data taking,
it is crucial to monitor and control the detector in real time. Environmental
conditions also need to be monitored for stable operation of detectors as well
as for safety reasons. In this article, we report the design, hardware,
operation, and performance of the slow control system.
