4.2 COMMISSIONING
The last step in the installation process is commissioning the meter. Commissioning is a 2 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/system-40/XXXX.
Commissioning Checklist
Part 1 Mechanical installation
Confirm that the flow sensor is properly located in the piping system (Sec. 3.1 & 3.2).
Confirm that the flow sensor is properly oriented with respect to flow direction (Sec. 3.2).
Confirm that the temperature sensor(s) is properly located in the piping system (Sec. 3.3).
Part 2 Programming
Confirm that the flow sensor location in the piping system (supply or return) is programmed into the meter

4.2.1 Commissioning following initial power-up
During initial power-up, the following display pages will appear the commissioning option
is selected. The settings shown below allow the installer to set 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 next page.
