SYSTEM-20 BTU METER
The last step in the installation process is commissioning the meter.
Commissioning is a two-step process. The first step is to review the mechanical
installation to confirm that the flow sensor and temperature sensor(s) are
properly located in the piping system. The second step is a review of the
meter program settings. Both steps must be completed in order to finish the
installation. A simple commissioning checklist is shown below. A copy of this may
be found online at www.onicon.com/system20.html.
4.2 COMMISSIONING
Commissioning Checklist
Part 1 Mechanical Installation
Confirm that the system components are installed
in the correct locations (Sec. 1.5 & 3.1).
Confirm that the flow sensor is properly installed
and correctly oriented with respect to flow direction
(flow meter manual).
Part 2 Programming
Confirm that the flow sensor location in the piping
system (supply or return) is programmed into the
meter (Sec. 4.1 & 4.2.1).
Verify that the Units of Measure Settings in the
meter are correct (Sec. 4.1 & 4.2.1).
Confirm that there are no alarm indications and the
meter is functional (Sec. 4.1.2 & 5.0).

Initial Power-up
4.2.1 Commissioning Following Initial Power-up
During initial power-up, the display pages will appear when the commissioning option
is selected. The settings shown below allow the installer to set MODBUS® or BACnet®
parameters, the flow sensor location (supply or return pipe) and the date and time. If the
factory pre-programmed engineering units for flow, energy and temperature are correct,
press SAVE to exit commissioning once the correct date has been set. Momentarily press
NEXT if you wish access the remaining commissioning mode display pages shown on the
following pages.
