12 FAULT FINDING

Should there be a fault with the smart controller, the heat pump
or some of it's connected components, the alarm icon will be
displayed on the smart controller touchscreen display when
viewing a heating or DHW circuit.
Tapping the icon will display a list of the current and historical
alerts. Refer to Table 7-1 for more information.
If a wired or wireless thermostat is configured, this will also
display an alarm code. Refer to Appendix A & B for thermostat
alarm code lists.

ALARMS

12.1.1 TEMPERATURE SENSOR ERRORS
If the alarm is an error for Circuit (Circuit 2 or 3), outdoor
temperature, upper/lower buffer water or DHW cylinder
temperature sensor, you should:
• check the temperature sensors are connected correctly to the
wiring centre. These will be connected between terminals 38
and 50 of the wiring centre (15V DC). Refer to Section 5.4
• check for loose connections on the sensors and wiring centre
terminals.
• check the sensors have been installed correctly and are not
damaged.
• check the sensors have been installed as per the system
scheme. (e.g., Outdoor temperature sensor has been
configured but not installed as the heat pump was intended
to be used).
12.1.2 NO CONNECTION TO HEAT PUMP
If the alarm is 'No communication with the heat pump module',
you should:
• check the heat pump had power and the isolator is set to ON.
• check that both the connection and polarity of the wires for
the Modbus connection between the wiring centre and the
heat pump are correct.
Refer to Section 3.12 for Modbus connection between the heat
pump and wiring centre.
12.1.3 NO FLOW DETECTED
If the alarm is 'No Flow detected', you should:
• check the Smart flow sensor is connected to the Smart
controller wiring centre correctly.
• check the Smart flow sensor is configured correctly on the
Smart controller. Refer to Appendix E.
• check the heat pump is working correctly.
12.2

THERMOSTATS

For issues when attempting to pair or use additional thermostats
on the smart controller, you should:
• check that the wired thermostat or wireless receiver has been
connected correctly to either the G1 or G4 sockets.

Section 12: Fault Finding
• check the wireless thermostat has been paired. Refer to
Appendix B.3.2 and A.1 for thermostat status information
from the display.
• check the thermostats are paired to the space heating circuit.
• ensure thermostat addresses are different if multiple wireless
thermostats are being used, and you have the correct
thermostat for the circuit. Refer to Appendix B.3.2 and B4.
12.3

ECONET

The smart controller will give an indication on the touchscreen
display of the status of connection with the Econet24 external
services via the Econet cloud icon. Refer to Figure and Table 7-1
If the symbol is 'green', the smart controller has an active
connection to the ecoNET24 server.
If the symbol is red, the smart controller does not have an active
connection to the ecoNET24 server.
The first step will be to check the Wi-Fi hub. The LED indicators
on the front will aid in deciphering the issue.
Refer to Table 14-1 for information on LED indicators and how to
resolve faults.
Refer to section 10 for further information on the Wi-Fi hub and
connection to the wiring centre.
