Details on Heating Manifold/Cooling Manifold

Information on the Heating manifold and Cooling manifoldsection in the panel heating/cooling.

Displays the circuits assigned to the manifold ports of the manifold selected in the pipe run view and their parameters. You can edit assignment of circuits and assign other manifold cabinet sets and closed-loop control systems. Before assigning another closed loop control, it has to be created first and a control component has to be assigned to it.

Heating manifold/Cooling manifold

Manifold

Displays the pipe run and manifold name.

Supply water temp.

Specifies the supply water temperature of the manifold. You can set the supply water temperature for each manifold individually.

Manifold cabinet set

Specifies the assigned Manifold cabinet set. The button opens the Select a Manifold cabinet set dialog, in which other Manifold cabinet sets can be selected and accessories can be change or added, depending on the system.

Maximum number of connections

Shows the maximum quantity of connections of the manifold. The maximum number of connectors a manifold has depends on the manufacturer and cannot be be changed.

Connections radiators

Indicates how many radiators are connected to the manifold.

Connection sequence

In the Connection sequence area you can edit the arrangement of the circuits in the table. Single and multiple selected lines can be moved by one position or to the beginning or end of the table. The order of the remaining circuits remains unchanged and the numbering of the manifold ports are adjusted.

Close gaps: Automatically closes gaps in the numbering of manifold ports. The order of the circuits remains unchanged.

Table of circuit zones

Displays the heating or cooling circuit zones connected to the manifold connections and their parameters.

Column

Description

Supplied zone in controlling room

Displays the name of the supplied zone. The naming is done according to the following scheme:

if necessary building parts no./Storey no. / if necessary Apartment no./Room no. - Zone type room name if necessary dimensions of the laying sheets.

Reg.

Defines the regulation of the circuit.

: Opens the Select closed-loop ctrl system dialog, where the circuit can be assigned to another, previously created closed-loop control.

Note:

Since only one closed-loop control can occur in a room, the selection of a closed-loop control is automatically transferred to all circuits of this room.

If multiple zones from different rooms are combined to form a circuit or a Tichelmann circuit, the first room seen from the manifold lead is always assumed to be the reference room. This assignment can be changed in the Manifold Connection section.

Con. Length

Allows you to include additional connection lengths. An additional connection length is, for example, the last piece of the feed pipe from the floor up to the manifold port. Enter the sum of the additional connection lengths of the supply and return pipes. The additional connection length is taken into account in the material list and hydraulic balancing. The capacity output of the additional connection length is not taken into account due to the lack of spatial classification and the undefined laying spacing. You can also use the additional connection length to simulate the entire feed pipe length as a temporary approximation.

m kg/h

Displays the mass flow rate of the circuit.

v m/s

Displays the flow velocity of the circuit.

L m

Displays the total length of the circuit including feed pipes of the circuit. Additional connection lengths specified in the Con.-length column are not considered.

dp mbar

Displays the total of the pressure losses of the pipes and the completely open valve. For volume flow control units, the minimum working pressure is also considered.

dp V mbar

Indicates the additional pressure loss of the valve set for balancing the circuits.

dp tot. mbar

Displays the total pressure loss of the circuit with the valve set.

Valve setting

Displays the flow rate or the setting value of the regulating valve, depending on the manifold type.

For manifolds with flow meters, the valve position is specified in l/min. For manifolds with regulating valves, the setting value of the valve is specified (e.g. with rotations as the setting value). The data always refer to the selected products of the manufacturer.

Toolbar buttons

Button

Description

Room view

Switches to the room view of the room whose zone is selected in the table.

Draw manifold in CAD

Switches to the CAD program to draw heating manifold.

Connect heating/cooling circuits

Switches to the CAD program to draw in feed pipes from the circuit zones to the manifolds.

Draw expansion joint

Switches to the CAD program to draw expansion joints there. This function is enabled if you defined and drew in a laying area.
