5) EarthLinked® Diagnostic and Monitoring system (EDM)
The EarthLinked® Diagnostic and Monitoring system (EDM), as shown in Figure 7, provides real-time
remote monitoring and tracks pressures, temperatures, power consumption and thermostat signals. It
connects via Internet, Bluetooth, USB and SD card. The EDM system is factory-installed in all PRIME
series units. Sensors are already connected to respective components and the system will begin
collecting data at unit startup. The EDM system has the ability to send data remotely to the Earthlinked
online
Dealer Dashboard when connected to the homeowner’s internet router with an Ethernet cable.
Technicians can also wireless access the EDM data onsite with a Bluetooth connection to a phone or
tablet. For homeowners without Internet access, or as a secondary data backup, the EDM system has
an onboard SD Memory Card Writer that records the time, date, and sensor/signal values that can be
personally graphed or uploaded to the Dealer Dashboard for review.
For more information on the EDM system, refer to the EDM-IOM manual .
6) Air Zoning
Prime series compressor units are compatible with Air Zoning thanks to the Nano-PLC (see Appendix
for more information).
When zoning a forced air system, it is recommended to design the smallest zone of the system so that
it has the air flow capacity to support the minimum airflow requirement of the system (400 CFM /
nominal) while the system is in a second stage without exceeding
1” WC total static pressure
across
the Air Handler unit when only that zone calls.
AVV Series Variable Speed Air Handlers should be used in any zoning application .
Bypass dampers between the supply and return plenums should not be used.
In the event that a zone is too small to meet the requirements above, the Air Zoning Option kit (AZO-
KIT) must be purchased and installed . Such a designed zone may in fact never see a second stage
call, which will force the system into a 5 minute second stage maintenance cycle from time to time to
ensure oil return from the field back to the compressor unit.
IMPORTANT!
Failure to meet this requirement can result in shortened blower motor
life, noise issues and can cause performance, efficiency and reliability
issues with the compressor unit itself.
