4.1.6 Hydraulic integration
Example 1 – bDFT020
Hoval BioLyt with one or two heating groups and calorifier
starting from distributor.
Important notes:
•
The hydraulic schematic merely shows the basic principle
and does not contain all information necessary for
installation. Installation must be carried out according to
the conditions on-site, dimensioning and local regulations.
• With underfloor heating, a flow temperature limit
thermostat must be installed.
•
Shut-off devices to the safety equipment (pressure
expansion tank, safety valve, etc.) must be secured
against unintentional closing!
•
Install sacks to prevent single-pipe gravity circulation!
