Editing heating/cooling zone data
- Selecting a covering.
Mark selected Heating/Cooling Zone components and specify the type of Covering in Data table window. - Change type for Heating/Cooling Zone.

- Mark these Heating/Cooling Zone where no loops are to be arranged and change their type to Without pipes.
- Determining the presence of peripheral zones.
Specify and configure Peripheral zone (PZ).For more information, see: Defining a peripheral zone.
Inserting Manifold components
- Insert Manifold on every storey. Manifold is inserted in the drawing together with manifold cabinet.
For more information, see: Manifolds for radiant system and their accessories.
Pipe feeds routing
- Connect Heating/Cooling Zone with manifolds using Pipe feeds route. Pipe feeds route enables automatic generation of pipe feeds.
For more information, see: Editing pipe feeds in a radiant system.
Editing an installation - feed to manifolds
Inserting Source

For more information, see: Connecting storeys with the "Stack" element.
Distribution
- Connect Source, Manifold, Riser with each other by drawing the network using the Pipe-run component and the AUTO and ORTO modes.
- (Optionally) use the Automatically connect terminal units function.
Inserting fittings
- Insert Valve onto pipe-runs.
- Select Valve type in Data table.
- Use Copy - Paste to insert fittings of the same type onto other pipe-runs.
Verifying correctness of installation structure
- Verify the correctness of the installation structure using the Check connections function (Key shortcut: Shift + F2).
- Verify the correctness of the installation structure and find conflicts using 3D view.
For more information, see: Verification of the correctness of installation structure.
Adjusting installation parameters - manual modifications (optional)
- Change feed temperature of the radiant system by using control circuits, which can be found in General data window in Thermal systems/Sources.
- Change pipe spacing and temperature drop in individual loops.
For more information, see: Interactive calculations of radiant systems. - Change structure of heating floor\wall.
- Change Max. press. drop in circuit.
Calculations and diagnostics
- Launch complete calculations by clicking the icon in the Calculations section of the toolbar.
- Open the Diagnostics window by selecting it in the list of windows or by pressing F8.
- Carry out an interactive verification of results in the Interactive radiant systems calculations window.For more information, see: Interactive calculations of radiant systems.
- After calculations are completed verify the messages listed in the Diagnostics window. If error messages are displayed, these must be eliminated in the first place.
For more information, see: Calculations and diagnostics.
Particular attention must be paid to:- Coverage of heat or cold demand.
- Correct routes of feeds generated automatically.
- Layers of heating/cooling surfaces selected to take account of undesirable differences in the heights/thicknesses of adjacent surfaces.
Editing an installation and its parameters
At this stage manual modification can be made of the installation and its parameters within the following scope:
Modifying the dividing line of element Heating/Cooling Zone to elements Heating-cooling surface

Editing an installation - dry radiant systems
The course of designing dry systems essentially follows that of the wet systems.
Additionally it is possible within a Heating/Cooling Zone type component to insert dry system plates and cut them to fit within room borders or to fit to the edges of other plates. The resulting quantities of plates are then included in the bill of materials. In addition, when routing the feeds and loops, it is necessary to take into account the arrangement of grooves in the dry system plates.
Editing general data and creating the building structure
Specify default data in General data:
- On the Floor systems tab, field Default system / fastening method, select the dry system of the particular manufacturer.
- Other data in accordance with: Editing general data and creating the building structure.
