Testing and maintaining the NVC-2
Using temperature test mode
Temperature test mode allows you to test your equipment and settings by simulating the
temperature. In temperature test mode, you adjust the “test temperature”.
As you increase or decrease the test temperature, the relays operate according to their settings and
the test temperature. This gives you an idea of how your system performs over a full range of
temperatures. The relays remain operating according to the test temperature until you exit test mode.
When the NVC-2 is in temperature test mode, it operates the equipment
according to the test temperature, not according to the measured temperature.
The NVC-2 does not exit test mode automatically. When you are finished testing,
