Balancing
14 After the calibration cycle is done the measurement begins and values for the connected valve are displayed.
15 Press function key Continue.
16 Shut the valve and then press the function key Done.
17 Values for the closed valve are displayed. Press function key Continue.
18 Re-open the valve to the previous setting as displayed and press function key Continue.
19 The selected module appears on the display. Navigate
to the next valve you wish to measure. Press function
key Measure and repeat the process from item 11.
20 Continue to measure all valves in the module until they are all marked with a green tick. Follow the sequence as
above and instructions on the display. To check current status of the valves in the module press View measured
data from the Options menu.
21 When all valves in the chosen module are measured select Calculate from the Options menu.
22 A table of diagnosed Differential Pressures (Dp) in the module is displayed on screen. The diagnosed Differential
Pressures correspond to the pressure drops that will happen in each circuit and distribution pipe segment
(supply+return) when design flows will be obtained in all circuits.
23 Navigate
in the diagnostic table to compare the diagnosed values to the design Differential Pressures (Dp) if
you have downloaded a calculated hydronic network from HySelect. Press function key Continue.
24 Calculated setting for each valve in the module are shown in a list, adjust the valves accordingly.
25 Repeat the balancing process as above (item 6-24) for each module in the Hydronic Network.
26 To verify the completeness of the balancing process a control measurement of each valve should be performed.
27 The collected data from the control measurement can be uploaded to HySelect and used for a Balancing report.
Balance a Hydronic Network with TA-Wireless
The TA-Wireless method makes use of wireless technology and simultaneous measurement with two Dp sensors
for balancing a hydronic network. It minimizes the number of access to each balancing valve. Required equipment
is two Dp sensors and two or more long distance transmission relays (required for balancing inside buildings over
more than 20-30 m or across multiple floors).
When balancing a predefined hydronic network the action can be started either from the Balancing function, as
described below, or directly from the function Hydronic Networks, see page 23. The method and required actions
are then the same.
1 Select
Balancing from the main menu, press enter.
2 If required, adjust the acceptable flow deviations in design conditions with Balancing Tolerance (also available in
Settings menu, see page 37).
3 Select TA-Wireless method. Press enter.
4 A general description of the TA-Wireless method is displayed. Press function key Continue.
5 A drop-down list of networks stored in your TA-SCOPE is displayed. Navigate
to desired network and press
enter. If no Hydronic Network is stored the only available option is New Hydronic Network.
6 Select An existing module, press enter.
7 The selected network appears on the display. Expand
the network and navigate to the module where the
balancing should start from.
8 Ensure the essential balancing prerequisites displayed in the list are fulfilled, press function key Continue.
9 A list of options appears on the display. Select Perform Balancing and press enter.
Tips! Make sure that you have two Dp sensors available and that your TA-SCOPE is set in
two Dp sensors mode before starting balancing with the TA-Wireless method, see Wireless
signal on page 37.
