Technical data

The controller can manage the valves in each individual zone or
alternatively pumps, depending on the set temperature.
The system decides whether to activate the unit or the most
energy efficient resources to meet demand.
NadiSystem manages different temperature levels based on the
terminal units used.
The heat pump directly produces water at the right temperature
for the system terminals connected to the high temperature cir-
cuits (e.g. fan coils, radiators, towel rails in bathrooms), while
low temperature radiant panels are controlled by the mixing
valves according to the specific compensation curves.
This means a compensation curve can be applied to the high
temperature zones and different compensation curves for each
low temperature zone (maximum three).
Depending on the type and complexity of the system, expan-
sion modules are required for connection of the components
managed by the system (pumps, valves, probes etc.), as indi-
cated in the table.
Simple installation by serial connection of the components mak-
ing up the NadiSystem.
