INTRODUCTION
2.3 Example of Installation – Diagram 4 (4.2) : Standalone with 2 low heating temperature zones (30-
40°C) or 2 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
dual zone low temperature heating fl oor
(= outlet temperature < 40°C).
Zones must be same temperatures.
