Error C-09: Aerothermal Gateway-Production Control Board Communication Error
The system loses communication with the Gateway and, therefore, with the aerothermal system. The control of the system will
be disabled, enabling the system to work from the manufacturer’s thermostat. To solve this incident check:
1. Verify that the Gateway is properly connected to the unit port of the Production Control Board.
2. Check the status of the LEDs of the gateway. To do this check the self-diagnose section or the technical sheet of the
gateway.
AC unit error: Error in the AC unit
Check the type of error in the AC unit thermostat and follow the instructions provided by the manufacturer.
AIRZONE LITE THERMOSTAT (AZCE6LITE [C/R])
Lite thermostats incorporate LEDs that detect malfunctioning.
Status LED blinking red quickly: Wired Lite thermostat-Main control board communication error
This incident is blocking. It blocks the control of the zone. Check that "Error 1" not appear in all thermostats. If so, verify the
proper operation of the main board. To solve this incident check:
1. Main control board status: Correctly powered.
2. Main control board status: Airzone connection bus LEDs are operating properly.
3. Connection: Verify the polarity of the main control board and thermostat connectors.
4. Wiring: Check that the voltage between the poles (A/ -) and (B/ -) is correct (1.8 Vdc).
5. Restart the zone and re-associate it with the system. To do this, pull down all the microswitchs, reinsert the thermostat
in its base and press on the thermostat. The LED will flash green twice when the reset process is completed.
6. Restart system: If the system is restarted, this error may be displayed in the thermostats at the beginning of the process.
This message should disappear after around 30 seconds.
