Using temperature override mode
Temperature override mode is for testing the SEC-HD configuration and settings. It allows you to
test the settings by simulating the temperature. Instead of adjusting the output of a variable stage or
state of a relay, you adjust the “test temperature”.
As you increase or decrease the test temperature, all stages and relays operate according to their
programmed settings and the test temperature, giving you an idea of how your system performs over
a full range of temperatures.
 When the SEC-HD is in temperature override mode, it operates according to the
test temperature, not according to the temperature measured by the probe.
 The SEC-HD does not exit test mode automatically. When you are finished
testing, press Back until the control exits test mode.
