The double circulation unit can be use in any application and with any heating source.
For applications examples please check the data sheet of the product.
The manifold used in the Double Circulation Units is a hydraulic block with the function of a standard manifold or a manifold with hydraulic separation. To enable or disable one of the options simply turn the screw. The open bypass means that a certain amount of the flow will be sent back to the heat source – this option is required when heating source has its own pump or in case where there is a system pump outside the heating source (primary side of double circulation unit). The close bypass means that there is no flow which is sent back to the heating source, the flow is divided based on the flow capacity of the double circulation unit pumps. The pumps capacity is set to the current demand of each heating circuit. This option is required in applications where heating source do not have built in circulation pump or there is no system pump outside the heating source (primary side of double circulation unit).
The bypass function and its value can be chosen by right number of turnings of the screw.
The double circulation unit DDA111 (group with a direct and mixing supply) can be upgraded to the DAA111 (group with two mixing supplies) by using an upgrade kit DVA111 (art. no. 62100300).
The units can be downgraded to direct by changing the valve to a plug set and insulation shell cover (delivered on demand) – in case this is need please contact our customer service.
