Installation of different heating circuits...
3 zone circuits (radiator heating circuit)
■
3 low-temp. circuits (under floor heating circuit with
■
3-way mixing valve)
DHW production with DHW recirculation
■
The 3-way mixing valve control, to achieve the low-
temperature level of the under floor heating circuit,
an accessory kit for a heating circuit with mixing valve
is required.
IMPORTANT
System separation is required of underfloor heating
systems employing non-oxygen diffusion barrier tubing.
All components on the secondary side of the heat
exchanger must be made of corrosion-resistant materials.
