– Put the boiler's front panel back on by hooking it at the top,
pushing it forward and fastening it with the screws removed
previously.
– Attach the warning label, included with the supply, on the boiler
in a clearly visible position.

Filling

To fill the systems:
– Power the boiler and the Heat Pump by setting the
respective general switches "IG" and main switches "IP" of
the appliances to "ON".
– Close the boiler's gas valve.
– Open all the automatic relief valves located on the boiler,
the Heat Pump and the HYBRID KIT (consult the instruction
manuals of the appliances).
– Where possible, select the maximum speed for the pumps.
– Open the filling valve located on the lower part of the boiler
and fill the circuits until the pressure reading on the display
is around 1.6 bar then close it.
– Set all devices (TA, etc.) on the system to heating demand
mode, so that all the pumps can work for at least 10 minutes ,
making water circulate and facilitating bleeding of air.
– Put the thermostats back to the "non-demand" position.
– Repeat the operations of the previous point 2 or 3 times and
verify on the display whether the pressure of the system
when cold falls between 1.2 and 1.5 bar . If not, open the filling
valve until the correct value is reached.

WARNING
If the pumps struggle to prime, we suggest
connecting a drain pipe to the manual relief outlet
(3 - Fig. 2) of the HYBRID KIT and opening it. Close it
at the end of the process.

Operation

m
WARNING
Refer to the boiler manual for setting the parameters,
anomaly visualisation, etc.
NECESSARY SETTINGS
The settings required for the optimal operation of the
generators and systems, and for guaranteeing the utmost
comfort for the user, include:
A - Setting of the boiler PARAMETERS
The "mandatory" parameters include:
PAR 02: 6
PAR 14: 55 (°C)
Consult the boiler manual for the procedure to be observed.
B - Setting of the "SUMMER" or "WINTER" mode
These modes are set manually on both the boiler and the Heat
Pump, and MUST BE "IDENTICAL": in other words, "WINTER"
(heating) on both appliances or "SUMMER" (cooling) on both
appliances.

temperature
Operation in "heating" mode
The "Winter" operating mode must be set and the closing of
the room thermostat (TA) is interpreted as a request for heat.
The temperature set-point, for the Heat Pump, must be set by
the user on the Heat Pump.
The boiler or Heat Pump, or both, and the system delivery
pump (PMI) activate to reach the delivery temperature set
on the boiler's control panel and measured by the system
delivery sensor (SMI) (fixed value or climatic curve depending
on whether an external sensor is present).
The choice of the generator is defined by the convenience
calculation described further below.
NOTE
The maximum set value of the delivery temperature must be
compatible with a safety thermostat (if present) of the system
used (e.g.: mixed system max. 50°C).
Operation in "cooling" mode
The closing of the room thermostat (TA), with the boiler
and the Heat Pump in "SUMMER" mode, is interpreted as a
cooling request.
The system delivery pump (PMI) and the cooling request to the
Heat Pump are immediately activated. The temperature set-
point, for the Heat Pump, is fixed and must be set by the user
on the Heat Pump.
"Domestic hot water" production
Domestic hot water (DHW) is always produced by the boiler
only, which has a rapid heat exchanger.
In "heating" or "cooling" mode, in case of a simultaneous
request from the room thermostat (TA), the system delivery
pump (PMI) continues to work together with the Heat Pump.
CALCULATION OF CONVENIENCE/SELECTION BETWEEN
GENERATORS
The electronics mounted on the boiler, only in "Heating" mode ,
automatically selects which of the two appliances – boiler or
Heat Pump – should conveniently work at any given time.
With external sensor installed
The calculation of the convenience of use between generators
is defined in relation to the temperature measured by the
external sensor compared with the set value of PAR 42 of the
boiler.
NOTE
In case of a "boiler anomaly", the convenience/selection is
forced on the Heat Pump.
Without external sensor
If there is no external sensor installed, only for calculating
the convenience between generators, the electronics takes
the value of the virtual outdoor temperature = 0°C as the
reference.
The user can decide whether to force the convenience of the
Heat Pump by suitably setting the value of PAR 42.
Activation of the convenient generator
The convenient generator (boiler or Heat Pump) is activated
