Mini Hub Radiator Circulator; Diverter Hub Radiator Mini; Electric Resistance Hub Radiator Mini - A2B Accorroni HUB RADIATOR MINI 6.0 Technical Information

7. MINI HUB RADIATOR CIRCULATOR

the electronic circulator supplied as standard HUB
RADIATOR MINI can feed:
- the floor heating system;
- the wall heating system;
- the radiator system;
- heating-only fan coil system.
In some cases MINI HUB RADIATOR can be
connected simultaneously to two or more
types of plants.
The power supply to the circulator has already been
carried out by our technicians during assembly
and allows the circulator to operate both when
the room thermostat requires heat, both when the
Flow switch indicates that water is being drawn
hot water.
In the case of radiant floor heating systems the
circulator will be controlled by the room thermostat
and the water delivery temperature comes
regulated by a three-way mixing point valve
fixed and the value can be modified to adapt it
to the design value of the plant. This valve
must be purchased separately as an accessory.
On the delivery pipe a
safety thermostat that blocks operation
of the pump, if the flow temperature, for
some reason, it exceeds the threshold value, so
to avoid overheating of the floor e
excessive dilatation of the same.
The characteristics of the circulator are shown on page
18, where the prevalence useful to the plant is shown
depending on water flow and
heating power of the heating system.
A water flow is normally considered
such as to obtain a delta in nominal conditions
temperature between flow and return of 10 ° C.
8. HUB RADIATOR MINI DIVERTER VALVE
All products in the HUB RADIATOR MINI series are
equipped with motorized diverter valve with return
spring loaded
The diverter valve is powered e deviates to the plant
automatically when the temperature of the technical
accumulation exceeds 47 ° C (parameter AR21),
vice versa below this temperature the system
remains in priority health inhibiting the functioning of
the circulator also in concurrent consent of the room
thermostat.

9. ELECTRIC RESISTANCE HUB RADIATOR MINI

All products in the HUB RADIATOR MINI series
they are equipped with a 1500W electric heater
single phase.
This resistance can be used both as a replacement
of the heat pump which in addition to the same.
the type of operation can be selected using the keys
on the control plate of the external cover cabinet.
A) Operation of heat pump only All keys must be in
position "0" with both LEDs off, in this way the
resistance electricity will never work
B) Resistance heat pump operation To use the
resistance to integration is enough press the "1" key
(led on) shown in figure e leave the "2" button in
position "0". In this way the control unit will decide
when help is needed of the resistance that will work
together with the heat pump.

Resistance only operation
Press both the green buttons (lit LEDs) and the
resistance will work in replacement of the pump
heat.
