4.5 ENTERING A NETWORK ADDRESS, SELECTING THE FLOW METER LOCATION &
ENABLING / DISABLING FRONT PANEL RESET
Before the System-10 can communicate on the P1 network, the flow meter location should be
programmed into the meter and the appropriate network address must set.
Identifying the flow meter location is particularly important for systems that will operate with
delta temperatures ≥20 °F. The default setting for the flow meter location is unknown. It should
be changed to the location setting that corresponds to the flow meter’s physical location in the
piping system. Choose supply when the flow meter is located in the pipe leading to the inlet to
the heat exchanger and return when the flow meter is located in the pipe leaving the outlet of
the heat exchanger. Leave the setting at unknown for bi-directional flow applications.
The application number is programmed into the meter at the factory prior to delivery, based on
the application information supplied by the customer. This application number can be changed
if necessary. Contact ONICON for additional instructions prior to attempting to change the
application number.
The System-10-P1 BTU Meter accumulates energy and volume totals in nonvolatile memory.
This memory can be zeroed directly at the meter or via the network. The direct method requires
the operator to scroll through the display menu pages until the subject energy or volume total is
displayed. The operator must then press the reset button on the front panel. The selected total
will then reset to zero. The next total to be zeroed is selected and the process repeated. The
front panel reset function, however, must be enabled for this to occur. It is disabled by default.
To select the flow meter location, enter a new device address or enable the front panel reset,
follow the instructions in the table below.
