The ProComm Electronic Commissioning Unit
The ProComm electronic commissioning unit has been developed in response to demand from discerning
commissioning engineers requiring an improvement in measuring techniques for differential pressures in
heating
and air conditioning systems.
The ProComm unit utilises state-of-the-art technologies in the field of electronics, software and hydraulic
protection for the sensitive measuring
element.
Health and Safety
Crane takes every reasonable precaution to ensure that ProComm commissioning units are designed,
constructed, calibrated and tested for safe and trouble-free operation when used in accordance with the
operating instructions.
For safe operation, it is important that commissioning
engineers read and understand the instructions
contained
within this manual. It is also very important that those employed in the function of
commissioning are aware of
the general hazards associated with the systems being commissioned.
When working with the ProComm unit, it is the user's responsibility to ensure that any Personal
Protective
Equipment (PPE) or clothing is worn as appropriate to the hazards potentially present.
It is also the user’s responsibility to understand the Health and Safety issues relating to high pressure
systems;
high temperature systems; and systems containing flushing agents, cleaning agents and/or
antifreeze agents. This list
is, however, not exhaustive.
Description of Unit
The ProComm unit comprises the following:
Hand-held electronic manometer in a removable rubber protector.
Quick-connect tubing set, complete with manually-operated isolation valves.
Pair of angle-pattern Binder-style adaptors.
Pair of straight-pattern Binder-style adaptors.

ProComm

System Defaults
The ProComm unit has been set up with default values for all the editable functions as follows:
Language = English Flow Alerts = Disabled
Pressure = kPa Back Light Timer = 5 minutes
Flow = l/s Auto-off Timer = 5 minutes
Specific Gravity = 1.00 Update Time = 1 second
Design Flow = 0 l/s Sample Time = 3 seconds
Target Flow = 0% View Size As = mm
Details of how to change these settings are provided in the various sections of this manual.
Automatic Alerts
Some automatic alerts may, on occasion, be displayed on the message bar at the top of the screen as
follows:
Zero DP SG (when specific gravity is not set to 1.0)
Low Battery High Temp (when internal temp. is high)
Change Battery
Connection
Note: each connection tube is fitted with an isolating valve and it is a matter of personal preference
whether the tubes are used with the isolating valves adjacent to the
ProComm unit or adjacent to the
subject measuring valve.
1. Before starting, ensure that:
a. Neither tube is connected to the
ProComm unit , and
b. Both isolating valves on the connection tubes are in the CLOSED position.
2.
Select the correct connection adaptors for the device being measured and attach them to the
connection tubes.
3. Attach the connection adaptor on the red connection tube to the high-pressure test point on the
subject measuring valve.
4. Attach the connection adaptor on the blue connection tube to the low-pressure test point on the
subject measuring valve.
5. Ensure that the equalising valve on the ProComm unit is OPEN (turn anti-clockwise) and then attach
the ProComm to the free ends of the red and blue connection tubes.
6. Open the isolating valves on the connection tubes. The differential pressure across the subject
measuring valve will generate flow through the connection tubes – from the high-pressure side to the
low-pressure side – and expel any air from inside the tubes.
7. Close the isolating valves on the connection tubes.
8. Press the ZERO button to set the datum at zero (if the unit is being subjected to an extreme
temperature change at this point, the datum may drift from zero as the internal temperature of the
unit changes and, in these circumstances, it will be necessary to repeat this process until the internal
temperature stabilises and a zero datum is maintained).
9. Open the isolating valves on the connection tubes.
10. Close the equalising valve.
11. The ProComm unit will now be reading differential pressure.
Please remember that the default setting for the Auto-Off Timer is 5 minutes i.e. the ProComm will
automatically switch off after 5 minutes of inactivity. If this happens, simply press the
MENU button to
switch the unit on again.
IMPORTANT SAFETY NOTE:
For safe removal of the ProComm unit, ensure that the equalising valve is OPEN before
CLOSING the isolating valves on the connection tubes. The ProComm unit and the connection
tubes can now be safely removed from the subject measuring valve.

There are seven options within the MAIN menu.
Select Valve
To select the manufacturer, use the ◄► buttons. To select the valve type, the valve fig. no. and the valve size,
use the ▲▼ buttons followed by the ◄► buttons for individual selections.
Important: Select all items on screen before using the button to accept them.
Valve Position (handwheel position)
When variable orifice valves are being measured, the handwheel position must be entered so that the
correct value of Kvs is used for the
derivation of the flowrate.
The screen shows the maximum and minimum recommended positions for the valve. The minimum
position shown ensures that the valve maintains reasonable accuracy.

Design Flow
The design flow for the selected valve can be edited in this screen.
When a value is entered, the actual flow will be calculated as a percentage of the design flow and will be
displayed on the Multi Display in the design flow box. Design flow can be entered in any of the units
selectable in the Units Menu.
Target Flow
The target flow for the selected valve can be edited in this screen.
When a value is entered, it will be displayed on the main display in the target flow box. Target flow must
be entered as a percentage and is generally derived when carrying out proportional balancing.
Typically,
the value used will be the same as the calculated design flow percentage on the index circuit. Balancing to
100% target on subsequent valves will ensure that valves adjacent to the index valve are balanced.
Pipe Size
Pipe size is entered if the user wishes to use the meter to establish the velocity in the pipe.
To display velocity, choose
a velocity unit from the Units Menu.

Flow/Pressure Display when a fixed / variable orifice valve is selected
The Flow/Pressure display is designed for most general commissioning purposes.
The type of valve selected (fixed or variable) is shown as a schematic symbol, with handwheel and Kvs
data in accordance with the selected valve.
The differential pressure and flow are displayed and continuously updated according to the signals being
received from the valve being measured.
Flow/Pressure Display when an automatic balancing valve is selected
If the design differential pressure is not met, the message LOW FLOW will be displayed. If the design
differential pressure is met, the message will be FLOW OK.

Multi Display when a fixed / variable orifice valve is selected
For commissioning engineers wishing to carry out commissioning using design and target flow, the Multi
Display can be selected.
The Multi Display is the most appropriate display when variable orifice valves are being measured.
Design flow and target flow are displayed. If the values for these parameters are set to zero, a series of
dashes are
displayed. The measuring valve selected is described in the scrolling bar at the base of the
screen.
When variable orifice balancing valves are selected and the design and target flow have been entered, the
ProComm
automatically uses the predictive handwheel position and displays this above the design or
target flow in their
respective boxes on the screen. When the valve has been adjusted to the predicted
position, use the
◄► buttons to adjust the handwheel setting.
Note: the design flow and target flow could be different
values, so it is important to use the correct
navigation button.
The predictive process is iterative due to the unknown valve authority in the circuit, so it will be
necessary to use this
feature more than once.

Multi Display when an automatic balancing valve is selected
The ProComm unit has the ability to display variables associated with automatic balancing valves. The
valve shown is an externally adjustable type.
If a valve is selected that is not adjustable (either internally or externally), the setting tab is not shown on
the valve image.
The design flow for any automatic flow controller will be achieved if the differential pressure across the
valve
reaches the design value. Each automatic balancing valve (and each setting for the valve) will possibly
have a
different design DP and the ProComm unit has the ability to hold the design DP for each
valve/setting.
Many of the automatic
balancing valves programmed into the ProComm have their actual characteristic in
the database. The level of
differential pressure across the valve will determine which data is used.
Generally, with automatic valves there is
a slight fall in flow when the DP reaches high values. This fact is
true for most automatic valves but, normally, the
fall in flow is within the stated tolerance for the valve.
When the ProComm is adjusted to select the correct valve/setting, the design flow is displayed within the
valve image. If the DP is not sufficient to create correct flow conditions, the box above the inlet pipe to
the
valve will display an up arrow and a value indicating that the DP will need to be increased to achieve
the
design flow. The value displayed is the design DP less the actual DP.
In the event of the actual DP being higher than the design DP, the box will display a
down arrow and a
DP value
that suggests a reduction in actual DP. On an index circuit this would suggest that the pump
speed could be
decreased to achieve the correct DP value.
If the design flow is not met, the message LOW FLOW will be displayed. If the design flow is met then the
message
displayed is FLOW OK.

Pressure Display
The differential pressure is displayed in large text. This screen is useful for users wishing to use the
ProComm as
a simple manometer.
About
The ‘About’ screen gives the unique serial number of the unit plus the unit’s firmware version.
DAMPING MENU
Use the ▲▼ buttons to select an option, followed by the button to accept it.
Update Time
This screen allows the user to change the apparent sensitivity of the ProComm unit.
The value can be adjusted by the user to increase or decrease the time delay between each screen
update. If the time is
short, the screen updates often. A long update time will give the appearance of a
steadier reading.
Use the ▲▼ buttons for coarse adjustment and the ◄► buttons for fine adjustment. A typical setting would
be 1 second. Note: increase this time on an unstable system.

Sample time
This screen allows the user to change the period over which the readings are averaged.
Use the ▲▼ buttons for coarse adjustment and the ◄► buttons for fine adjustment. A typical setting would
be 3 seconds.
This value can be edited up to a maximum of 11 seconds and it represents the base time over which the
readings are taken
for the rolling average system. A typical time of 3 seconds allows a large number of
readings to be taken before the mean calculation
is made.
The averaging system continues to use 3 seconds of measured values, but on a rolling average basis.
Increasing the sample time will make the screen appear to update slower, but with a more stable reading.
ADVANCED MENU
Flow Alerts
Flow alerts can be switched between Enabled and Disabled. The alerts relate to the flow through the
selected valve. “High
Flow” and “Low Flow” mean that the measured flow is outside the range normally
expected in the valve.
When working on unstable systems or systems that have little regulation, the alerts can
sometimes
impede commissioning operations and, in these circumstances, they should be temporarily Disabled.
Back-Light Timer
The Back-Light Timer sets the period of time that the Back-Light remains on. Pressing any key will
reactivate it.
Setting the light to a short time will preserve battery life.
Use the ▲▼ buttons to select an option, followed by the button to accept it.

Auto-Off Timer
The Auto-Off Timer sets the time the unit remains on. Setting the time to a short time will preserve
battery life.
Use the ▲▼ buttons to select an option, followed by the button to accept it.
View Size As
This screen allows the user to select the preferred units for selecting valve size. The default unit is
millimetres.
Use the ▲▼ buttons to select an option, followed by the button to accept it.
Quick Valve
This display allows the user to save the data from the current valve to a storage location on the
ProComm.
To use this feature, press the  button whilst viewing any of the display screens.
There are 100 storage locations available: arranged in ten groups, each of up to ten valves. The group
number can be
selected using the ▲▼ buttons and the valve number can be selected using the ◄►
buttons.
The MENU button gives the user the SAVE or DELETE options. If the screen is black, a valve is already in
the
location. However, if the screen is white it is possible to load a valve to this location.
13
ProComm

Using the SAVE command will overwrite the location with the current valve data.
The Quick Valve feature allows the user to save the selected valve to a memory location which is quickly
accessible without having to use the ‘Select Valve’ option. The purpose of this is to reduce time when
commissioning a system with, for example, three different types of valve. The three types of valve can be
saved to
the Quick Valve memory including the design flow designated for that valve. When recalled, the
valve will be
loaded to the unit including the design flow.
Follow the on-screen instructions to save the current selection or delete the existing saved valve.
An additional use for this feature is the ability for the user to save the commissioned data for up to 100
valves
for later reference when producing a commissioning report.
When the data for the selected valve has been saved, the following screen appears:
The example shown is for a variable orifice double-regulating valve. All other valve types have a simpler
screen.
When using automatic balancing valves, the procedure for using ‘Quick Valve’ is the same as for traditional
balancing valves but the screen showing saved data is different as shown below.
The above example shows that the actual DP is greater than the design DP and so the flow status is
displayed as FLOW OK.
Further options for saving valve data are available if PcomPRO Project Application Software is purchased
with the ProComm unit.
PcomPRO gives the user the option of preparing a ‘project’ on a computer
prior to
commissioning the system. The data from the commissioning process can be saved to the
ProComm unit for later
use.

Calibration
Factory calibration is carried out in controlled conditions, using calibration equipment which is traceable
to National Standards.
Generally, it is recommended that ProComm handsets are serviced and calibrated annually. However, this
is not a fixed period and more frequent service intervals may be necessary for extremely high-use meters
or for meters which are regularly used on very dirty systems or on systems that contain high
concentrations of cleaning agents / treatments.
Valve Database
The ProComm unit is pre-programmed with more than 4500 valves in its database.
Please note: whilst every effort is made to ensure that the valve data contained within the
ProComm is correct, valve manufacturers invariably reserve the right to
modify their products,
without notice, and so Crane cannot be held
responsible for any inaccuracies or omissions . The
user is advised to check
the performance data (Kvs values) of specific valves prior to use.
User Interface
The ProComm unit is fitted with a memory card for holding data. There is not normally any reason for
accessing the
data on this card. Contact Crane for more information if valve data is to be updated as
there are some important
procedures to be followed to edit the data correctly.
