BCI-R / BCI2-R with Air-Fi Zone Sensor for standalone operation
Summary:
The Air-Fi zone sensor allows for standalone operation, meaning it can function independently without reliance on other devices and systems. This feature provided flexibility and convenience on managing HVAC zones
If there is not a Tracer SC on site, or it has not been installed, you must create a temporary network (even for one sensor and WCI). A wireless network must have one WCI that acts as a coordinator, and If you have multiple standalone controllers, create the coordinator in a central location.
There can only be one Coordinator per network. Multiple networks can be established if needed based on number of UC's or physical layout of site, in order to establish good network communications.
- To make the WCI a coordinator, and create the wireless network, press and hold the Start Button for 5 seconds. The CRD, NWK and Open Net LED's should light within a few seconds. If the Open Net LED does not light, press and release the Open Net button.
- Alternate method: Connect the Tracer TU service tool (with USB) to the controller, that's going to be the Coordinator. Click the 'Wireless' drop down menu in Tracer TU and then click "Create Network' The CRD, NWK and Open Net LED's should also light within a few seconds.
- On both methods of creating the network, the network will be held open for 1 hour to allow member WCIs that have been set with the same GRP/NET address as the Coordinator, to join the network. As each WCI joins the 1 hour timer is reset till all devices have joined.
- If you have multiple areas with standalone controllers, then create multiple networks. making sure to find centrally located WCIs as the coordinators.
A network must be established before a Air-Fi zone sensor will associate with a WCI.
- The Air-FI sensor group and net (gn) settings must match the rotary address on the WCI. This will allow it to become a member of the network
- The UC setting must match the rotary address of the unit controller. This will allow the sensor to associate with the specific controller
- The sensor (Sn) setting should be 1, unless you are using multiple sensors that are being used for zone temperature averaging.
- The network must be open for WCI's and sensors to join. the sensor may display an E2 code stating that it is not yet a member of the network It may take a few minutes for the sensor to join the network and the E2 error to be cleared from the screen. Pressing the center button twice will force the sensor to join of the network
- If the zone sensor is displaying a E1 code, it has not associated with the UC controllers, press the center button twice on the zone sensor to force the association and clear the E1 code.
6. With the Air-Fi sensor connected a jumper must be added to the RTRM on J6-1 and J6-2 so it will look at the Air-Fi sensor communicated values
When you are ready to install the SC on site, you must manually disband each of the previously formed networks before connecting and powering the WCI on the SC. The WCI on the SC will automatically become a coordinator, if there are existing coordinators with the same group and net settings then the WCI on the SC will not become the coordinator.
To manually disband a network: press and hold the start button on the coordinator WCI until the CRD LED goes out (roughly 10 seconds).
