GENERAL FEATURES
Options
Storing
and pumping
module
Standard pump Allows the circulation of the water on the plant side.
High head pump
Allows the circulation of the water on the plant side and guarantees a higher avai-
lable static head, suitable for high pressure drop plants.
Modulating pump
Allows the circulation of the water on the plant side with the possibility to set the
rotational speed of the pump in order to get the requested flow rate without the
necessity to install other setting devices.
Tank and
standard pump
Allows the circulation of the water on the plant side.
The thermal inertia of the buffer tank allows to reduce the number of compressor
starts and to guarantee a more stable flow temperature.

Integrative
electrical
heaters
Standard in the tank
Integrate or replace the heating power supplied by the heat pump and are managed
by the unit controller with a 2 step logic.
They are also activated as antifreeze electrical heaters.
Available only for the VA version.
Soft starter Reduces the compressor start current.
Compressor power factor correction
Allows to reduce the phase shift between the absorbed current and the power sup-
ply voltage keeping it above the value of 0,9.
Fans control
Modulating control
(condensation / evaporation
control)
The fans rotational speed can be modulated continuosly by an inverter to control
the condensation pressure (in cooling) and the evaporation pressure (in heating)
in order to extend the operating limits of the unit and to reduce noise emissions.
Electrical loads
protection
Fuses Allows to protect the electrical loads with fuses.
Thermal magnetic
circuit breakers
Allows to protect the electrical loads with thermal magnetic circuit breakers simpli-
fying the maintenance operations.
Chiller (IR) without options (VB) Heat pump (IP) without options (VB)
