During normal operation the display shows the temperature, humidity and dew point on the bottom line. When either measurement is within the alarm threshold, the value flashes. To adjust the display contrast, turn the contrast knob clockwise (right) for the increased contrast, and counter-clockwise (left) to reduce the contrast. The display periodically shows additional status information such as date and time, battery backup operation, battery low condition (during battery backup operation), and sensor failure.
To view the current alarm or delay settings, press and hold the corresponding button. For instance to view the temperature high alarm, press and hold the TEMP HI button.
To modify an alarm threshold or alarm delay, press and hold the corresponding button. While continuing to press the button, press the UP button to increase the value, or DOWN button to decrease the value. Note, the UP and DOWN buttons are only active if the alarm modification function is unlocked in the setup menu.
If an alarm is active, the SILENCE
button will silence the beeper and deactivate the relay. If
the SILENCE button is pressed
while there is no alarm, it has no effect on the beeper operation. The
Silence alarm function is only active during the current alarm occurrence.
Once the
alarm condition is over and the unit returns to the normal (non alarm)
operation, the silence alarm function is automatically deactivated.
