What you need to know before configuring your SEC-HD
Configuring your SEC-HD means telling it what equipment it will be controlling and how it will be
controlling that equipment. For example, your SEC-HD has three relay stages. You need to tell the
stages if they will be controlling heating or cooling elements.
Before you begin configuring your SEC-HD, make sure:
 It has power
 All equipment has been properly connected to the correct terminals.
 You know which equipment is connected to which relays and variable stages
This chapter does not explain set points, idle speeds, or other settings. For
information about those settings, read Chapter 4: Programming your SEC-HD on
page 26.
 We recommend configuring all your control elements before programming the
settings (temperature set points, idle speeds, and so on). Use the Appendix E:
Configuration worksheets on page 56 to help you keep track of which equipment
is connected to which relays and variable stages.
 If you receive an error message during configuration, look it up in Appendix B:
Troubleshooting on page 50 and then follow the instructions for correcting the
problem.
 Your SEC-HD's built-in diagnostic tests are useful for testing your equipment
after installing and configuring it. For more information, read Testing settings and
equipment on page 40.
