11.1 KEY OF ELECTRICAL DIAGRAMS HUB RADIATOR PLUS 250 - 400 SOLAR
All the products of the HUB RADIATOR PLUS SOLAR
series they are equipped with a 2000W single-phase electrical
resistance.
This resistor can be used either as a replacement
of the heat pump that integrates it.
the type of operation can be selected using the buttons
on the control plate of the cabinet of external cover.
A) OPERATION ONLY HEAT PUMP
The “IR” button in the figure must be in the OFF position
“key O”, in this way the resistance electric will never go
into operation
B) OPERATION WITH ACTIVATED SUPPORT RESISTANCE
To use the integration resistance just press the “IR” key
in the ON position “I key” and the “DR” INTEGRATION
“key II” key. In this way the control unit will decide when
it is necessary the help of the resistance that will work
in tandem to the heat pump.
C) OPERATION WITH ALWAYS ACTIVE RESISTANCE
To use only the resistance in place of the pump
heat, just press the “IR” button
in the ON position “I key”
and the “DR” EMERGENCY “key I”.

N.B. Before making connections
make sure you have
correctly sized the section
of the power cables
based on the actual distance
