GENERAL FEATURES
Options
Source side
flow rate
management
Pump
Allows the circulation of the water on the source side.
2 way valve
Modulates the water flow rate on the source side when the water circulation
is assured by an external pump.
Domestic hot water
production
3 way valve
Allow to divert the hot water produced by the heat pump from the heating cir-
cuit to the domestic hot water circuit.
3 way valve with
primary heat exchanger
The hot water is diverted by the three way valve on an internal heat exchan-
ger. An internal pump assures a correct domestic hot water flow through the
other side of the heat exchanger.
3 way valve with secon-
dary heat exchanger
(for integrated tank)
The hot water is diverted by the three way valve in a tank integrated in the
unit (accessory). The domestic hot water is generated istantaneously by
means of an internal heat exchanger and a modulating pump.
Passive cooling
Allows to use the source to cool down the plant water without activating the
compressor.
Integrative electrical heaters
Integrate or replace the heating power supplied by the heat pump and are
managed by the unit controller with a 3 step logic.
Soft starter
Reduces the compressor start current.
The controller flexibility and the big number of options availa-
ble allow to get, for each model, a lot of
different configura-
tions
that integrate inside the heat pump many components
of the plant and allow to realize compact and tested installa-
tions.
In order to select the right configuration it is necessary to defi-
ne the type of plant to which the heat pump will be connected,
both for what concerning the heating and cooling circuits, and
for what concerning the domestic hot water management.
