Error Message No Communication
Error Message No Sensor
Error Message Wireless Sensor Lost
When the thermostat powers up, it will display the nC message
indicating it has not established communication with the Wiring Hub.
After about 10 seconds the thermostat will establish communication
with the Wiring Hub and the nC message disappears.
The nC message will appear anytime communication with the Wiring
Hub is lost or never established. Check the wiring between the
thermostat and Wiring Hub and that the wires are secured in the
correct terminals on the thermostat and Wiring Hub.
The thermostat displays the nS message indicating it has not detected
an upstairs temperature sensor. Check the wiring between the sensor
and Wiring Hub and that the wires are secured in the correct terminals
on the Sensor and Wiring Hub. If a wireless temperature sensor is
used, be sure the batteries are installed and the wireless sensor is set
to the correct number.
The thermostat displays the Err 01 or Err 02 message indicating it has
lost communication with an upstairs, wireless temperature sensor.
Check the batteries in the sensor and be sure they are set to the
correct sensor#. If the error message persists, turn the power off to the
Wiring Hub. When power is restored, the Wiring Hub automatically
detects which sensors are being used and clears the error messages.
When an nS error is detected, the thermostat fully opens the Upstairs
and Downstairs dampers and turns airflow control off as long as the nS
error persists. It still maintains control of heating and cooling calls.
When an Err 01 error is
detected, the thermostat
alternately displays
When an Err 02 error is
detected, the thermostat
alternately displays
