Common Issues

2.1

Communication problems

Communication problems can occur for the following reasons:
- PFRN wiring issues
- Incorrectly commissioned appliance
- Missing or un-configured modules
Before diagnosing a communication issue confirm that there is a minimum of one temperature module installed
and configured per appliance and a minimum of one ion pilot installed and configured per controller.
1. Check to see if the controller is communicating with the user interface by checking the appliance screen
(System Overview > Appliance) or the appliance wizard: System Overview > Settings > Appliance Wizard >
Assign controllers.
2. In the appliance wizard you can see the controllers that have a link but are not setup yet under Unassigned
controllers. Controllers here are communicating but still need to be commissioned. If the controller you are
looking for exists in the table, then commission the unit.
3. Controllers that have been previously commissioned but are currently not communicating are shown under
their associated appliance. The name of the controller if it is not communicating will be shown as "Not Set". If
the controller you are looking for is shown here but without communication or if the controller does not show
up in the list at all, then troubleshoot the link between the user interface and the controller.
4. If the controller shows up as having a link but there is still a communication alarm for the BMS, then there is
either a commissioning issue or a peripheral module (temperature, ignition, etc) has lost communication.

2.1.1 Controller communication problems

Check the following items if there is a controller communication problem.
1. Check that the controller is powered up. It should have 12 or 24VDC from a minimum of a 2 Amp supply plus
the required current for valves.
2. Update the system firmware. The firmware bundle on the UI and the controller must match in order for them
to communicate. If the controller does not show up in the firmware update screen continue troubleshooting
the connection.
3. Check the PFRN connection. Make sure the wiring is in the correct order and all connections are secure. Re-
crimp if necessary. Make sure none of the wires are touching each other, often this can happen if the wires
are stripped too long for the connector.
4. Check the continuity of the PFRN wires. When using hardwire sometimes the wire can break during
installation. Use a multi-meter to loopback the wires and check the continuity.
5. The link LED on the module should be a solid green. The link LED on the controller should be flashing green.
This indicates that there is some sort of communication, however it does not necessarily mean that the
communication is bidirectional. The LED can be flashing with one of the PFRN wires disconnected. If the LED is
off, this means there is no communication at all.
6. The Power LED should be solid blue on both the UI and controller. This indicates that the UI is receiving power
and that the controller is providing power.
