9. WINTER SUMMER DIVERTER VALVE
All products in the HUB RADIATOR DHP series are
equipped with summer / winter diverter valve
connected
electrically with the appropriate switch that must
each season change must be selected.
Summer / winter operation
With the green key pressed and the led on, the
system is in winter mode, with red button pressed
and led off the system is in summer mode.

ELECTRIC RESISTANCE HUB RADIATOR DHP
All products in the HUB RADIATOR DHP series are
equipped with a 1500W single-phase electric heater.
This resistance can be used as a supplement
of the same.
The type of operation can be selected
using the button on the control plate of the
external cover cabinet.
A) Operation of heat pump only
The key must be in position "0" with the LED off,
in this way the electric resistance will not enter
never in operation
B) Operation with activated resistance
support
To use the resistance to integration is enough
press the green button with the lightning symbol.
In this way the control unit will decide when it is
necessary the help of the resistance that will work in
heat pump support. In this mode the
led will be on.

CIRCULATOR
HUB RADIATOR DHP
the electronic circulator supplied as standard HUB
RADIATOR DHP can feed:
- the heating and air conditioning system
On the floor;
- heating and fan coil system
conditioning.
In some cases HUB RADIATOR DHP 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 while it is
running
rediscovering both when the room thermostat
requires heat, both when the minimum thermostat
falls below 45 ° C.
In the case of radiant floor heating systems the
circulator will be controlled by the environmental
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.
While for conditioning the circulator is
controlled exclusively by the room thermostat ..
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 given in
pag. 17, where the useful prevalence is reported
to the plant according to the water flow rate and the
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. DIVERTER VALVE HUB RADIATOR DHP
All products in the HUB RADIATOR DHP series
are equipped with electrically connected diverter
valve with minimum thermostat
This system allows to put momentarily in stand-by
the system for favor the production of domestic hot
water.
