Return Temp
provides the instantaneous return temperature of the system
tabulated by the meter.
Delta Temp
provides the instantaneous difference between the supply and return
temperature of the system is tabulated by the meter.
The default description and communication via each auxiliary input is “Counts.”
Each pulse is a count of an accumulated value from the remote device.
The System-40 allows the user to change this description through the
commissioning process. See section 4.2.2.3 AUXILIARY INPUT/ OUTPUT
CONFIGURATION SETTINGS for more details on changing the aux description.
Run Hours
provides the instantaneous total hours the meter has run.
* These screens will only appear if Aux I/O was configured at factory for
Pulse Input. See section 5.0 AUXILIARY INPUTS and OUTPUTS for more
information.
Important Note
When reviewing the Supply and Return temperature display pages, note
which one has the word “FLOW” in the lower left corner of the page. This
is an indication of the flow sensor location in the piping system. Verify
the actual location of the flow sensor in the piping system. It is critical
that the correct location (supply or return) be programmed into the meter.
Failure to do so will result in significant error in both the flow and energy
measurements.
