INTRODUCTION
2.4 Example of Installation – Diagram 4 (4.3) : Standalone + with 3 low heating temperature zones
(30-40°C) or 3 middle heating temperature zones (< 60°C)
i
Refer to the chapters “Hydraulic connection” and
“Electrical Connection” to connect the system.
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.
