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.
Toolkit including a set of hex keys (3mm, 4mm, 5mm, 6mm & 8mm) and a screwdriver.
Lanyard for attachment of the ProComm unit to pipework, etc.
Spare battery.
Operating Instructions, Quick-Start Guide & Calibration Certificate.
All the above are incorporated in a sturdy, lightweight, carrycase.
Connection and Set-up
General Navigation Buttons
Press the MENU button to switch the unit on. Once switched on, use the MENU button to enter the
menu screens.
Use the button for cancelling entries or for returning to previous screens. The button also allows
the ProComm to be switched off.
Press the ? button for context-sensitive help. Use the ▲▼ buttons to scroll through the help files.
When in a Menu screen or a Help screen, pressing the MENU button will give language options.

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.

The menu system is accessed using a single press of the MENU button. Then use the ◄► buttons to scroll
through the available menus.
When the correct menu is shown on the screen, use the ▲▼ buttons to select the correct function, which is
then accepted using the button.
Menu functions that require a numeric value to be added use a system which is best described using the
following example:
Example – Setting the design flow to 1.05 l/s.

MAIN MENU
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.

User Kvs
This screen allows for the user to enter the Kvs value of a valve which is not listed in the database of
valves.
When a Kvs is required for a variable orifice device, please remember that Kvs values will be
different at different handwheel positions.
Change SG (specific gravity)
This screen allows the user to enter the value of the specific gravity of the line fluid. Typically, this would
be used when glycol (or similar) is being used in the system.
Note: when an SG is set to a value other than 1.0, an advisory note is shown at the top of the screen.
UNITS MENU
This screen gives the user the option of selecting the preferred units for display on the ProComm.

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.
