Refer to Appendix 1 for Installation and Programming information before using this quick-start guide.
Appendix 2 outlines the sequence of operation of the Factory Run Test feature of the control. The unit software,
as shipped from the factory, contains the Factory Run Test program. The Factory Run Test feature is used by the

By running the program you can easily determine that all the key electrical components of the unit are working
properly. See Appendix 2 for directions on how to turn on the Factory Run Test feature as well as a description of
