b This diagram shows the case of an installation with
a three zone low temperature heating fl oor (= outlet
temperature < 40°C).
Zones must be same temperatures. i
Refer to the chapters “Hydraulic connection” and
“Electrical Connection” to connect the system.
i DHW components only necessary with sealed
system or open vented installations. Hot water
production can be via a combi boiler instead.
