LED STATUS
The NT-DRS includes a Diagnostic LED that can help you
troubleshoot your installation and sensor operation.
LED Off:
LED OFF indicates no power to the NT-DRS or thermostat. Check
wiring of your sensor and the thermostat for problems. Fix as
necessary.
LED On Solid During Power-Up:
On power-up the LED will turn on solid until the NT-DRS
successfully communicates with the thermostat. If the connection
is successful, the LED will blink according to its conguration. If
the remains on, there is a communication problem. Check wiring
and x as necessary.
LED On Solid After Power Up:
If the NT-DRS loses connection with the thermostat for 60
seconds, the LED will turn on solid. Check the wiring and x as
necessary. Cycle power cycle power and recheck the LED status.
LED Triple Blink (Probe Operation)
The NT-DRS LED will blink three times when the thermostat
requests data. This occurs approximately every 16-20 seconds.
LED Fast Continuous Blink (Lost Probe)
If the NT-DRS loses communication with the probe, the LED will
continually blink fast. Check wiring and probe and x as
necessary.
ANOTE: In this condition, the NT-DRS will stop reporting until
the communication with the probe is xed.
