GENERAL FEATURES
Control system
The microprocessor controller is able to manage not only the
unit itself but also all that components of the plant which allow
to realize a complete system.
The main
functions
of the control system are :
- room temperature control according to the outdoor tempe-
rature (climatic control)
- domestic hot water production (management of 3 way
valve, storage tank, anti legionella cycles…)
- management of a heating and/or cooling mixed circuit
(pump and 3 way mixing valve)
- management of a heating direct circuit (only pump)
- management of a storage tank for heating and/or cooling
- management of electrical heaters for heating and dome-
stic hot water (3 steps logic)
- solar panels integration
- passive cooling
- room humidity control for cooling with radiant systems
- internal programmer clock (for heating, cooling and dome-
stic hot water)
- digital input for electrical energy low tariff
- alarm memory management and diagnostic
- compressor and pump operating hour counter
- possibility to manage more units in cascade (maximum 16)
Besides the standard user interface present on all the units,
wired or wireless remote thermostats are available which
allow to control all the operating parameters of the unit and to
acquire the temperature in the different zones in order to rea-
lize a more precise and comfortable control.
The unit controller is able to manage a lot of different plant
solutions enabling automatically the necessary control
algorythms according to the components which have been
connected.

The controller is able to manage up to
two zones in heating
(one by means of a mixed circuit and the other by means of a
direct circuit) and
one zone in cooling
(by means of a mixed
circuit).
It’s possible to realize more complex plants connecting to the
heat pump controller further expansion modules in order to
extend without limits the number of zones to be managed.
For each zone the following parameters can be set :
- set point
- daily or weekly operating time table
- climatic control curve
- room control sensor : it can be in common with the other
zones or independent (in that case it’s necessary to install
an additional room thermostat)
