Using temperature override mode,
parameter 29
Temperature override mode is for testing the TVS 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 TVS is in temperature override mode, it operates according to the test
temperature, not according to the temperature measured by the probe.
 The TVS does not exit test mode automatically. When you are finished testing,
press
Back until the control exits test mode.
