7 OPERATING MODES HUB RADIATOR PACK CF
7.1 ONLY OPERATION OF THE HEAT PUMP
The
IC
button (boiler switch) must be set to OFF, while the CD
digital controller must be set
“to heating ON” mode (the
display will show the green “SUN” symbol and the storage
temperature). In this way the system will work with only the
renewable energy of the heat pump.
In any case, the boiler will remain in operation during the summer
phase to guarantee the instantaneous production of domestic
hot water.
7.2 HYBRID OPERATION, HEAT PUMP WITH BOILER
INTEGRATED WINTER PERIOD
The
IC
key (boiler switch) must be set to ON, the I E / I key
(summer / winter switch) must be set to WINTER while the CD
digital controller must be set “to heating mode ON” (the display
will show the green “SUN” symbol and the storage temperature).
The digital controller of the CC boiler must be set in WINTER
mode.
In this way the system will operate in hybrid mode with the boiler
active in support of the external Booster in HP upon call from the
external probe Pb2.
7.3 HYBRID OPERATION, HEAT PUMP WITH SUMMER
INTEGRATION BOILER
IThe IC key (boiler switch) must be set to ON, the I E / I key
(summer / winter switch) must be set to SUMMER while the
CD digital controller must be set
“to cooling ON mode”
(the
display will show the green “SNOWFLAKE” symbol and the
storage temperature).
The digital controller of the DC boiler must be set in DHW mode.
In this way the system will operate in hybrid mode with the boiler
active for the production of DHW and the external Booster in HP
active to produce chilled water up to 4 ° C to power the hydronic
terminals.

6. HUB RADIATOR PACK CF CIRCULATOR
The electronic circulator is supplied as standard and can
supply a single hydraulic circuit or alternatively a boiler room
manifold to which additional circulators will then be applied.
The power supply of the circulator has already been carried
out by our technicians during the assembly phase and allows
the circulator to work both when the room thermostat requires
heat.
In the case of a radiant floor system, it is necessary to purchase
the system mixing valve accessory which will be installed in
the factory together with the circulator.
The mixing valve is available in 2 versions:
- Fixed point mechanical version with manual adjustment
- Motorized version with managed external climatic probe
automatic
A safety thermostat must be installed on the delivery pipe that
blocks the operation of the pump, if the delivery temperature,
for some reason, exceeds the threshold value, in order to
avoid overheating of the floor and its excessive expansion.
The technical characteristics of the circulator are shown in
the graph below and must be verified from time to time by
a qualified heating engineer to assess that the circulator is
suitable for powering the reference system.
