NIBE™ F1255Chapter 1 | Important information6
F1255 – An excellent choice
F1255 is part of a new generation of heat pumps, which have been intro-
duced to supply your home with inexpensive and environmentally friendly
heating and/or cooling. Heat production is safe and economical with in-
tegrated hot water heater, immersion heater, circulation pump and control
system.
The heat pump can be connected to an optional low temperature heat
distribution system. e.g. radiators, convectors or under floor heating. It is
also prepared for connection to several different products and accessories,
e.g. extra hot water heater, ventilation recovery, pool, free cooling and
climate systems with different temperatures.
An immersion heater of 7 kW can be connected automatically if anything
unforeseen should occur or as reserve operation (then 6 kW).
F1255 is equipped with a control computer for good comfort, good eco-
nomy and safe operation. Clear information about status, operation time
and all temperatures in the heat pump are shown on the large and easy
to read display. This means, for example, that external unit thermometers
are not necessary.
Excellent properties for F1255:
႑Inverter controlled compressor
The heat pump has an inverter controlled compressor that automatically
adapts itself optimally and economically to your house and supplies your
installation with renewable energy.
႑Scheduling the indoor comfort and hot water
Heating and hot water as well as cooling and ventilation in some cases,
can be scheduled for each day of the week or for longer periods (vaca-
tion).
႑Display with user instructions
The heat pump has a large display with easy-to-understand menus that
facilitate setting a comfortable climate.
႑Simple troubleshooting
In the event of a fault, the heat pump display shows what happened
and the actions to be taken.
