Direct Acting BEIGE units (CSC–2001/2003/2007/
2009/2017) are designed for normally open dampers
with direct-acting thermostats for cooling and re-
verse-acting thermostats for heating.
Reverse Acting GRAY units (CSC–2002/2004/2008/
2010/2018) are designed for normally closed damp-
ers with reverse-acting thermostats for cooling and
direct-acting thermostats for heating.
