NIBE™ F750Chapter 1 | Important information6

F750 – An excellent choice
F750 is part of a new generation of heat pumps, which have been introduced
to supply your home with inexpensive and environmentally friendly heating.
Heat production is safe and economical with integrated hot water heater,
immersion heater, circulation pump and control system.
The heat pump can be connected to an optional low temperature heat distri-
bution system. e.g. radiators, convectors or under floor heating. It is also
prepared for connection to several different products and accessories, e.g.
extra water heater and climate systems with different temperatures.
F750 is equipped with a control computer for good comfort, good economy
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 F750:
႑Integrated water heater
There is a water heater integrated in the heat pump, which is insulated
with environmentally friendly cellular plastic for minimal heat loss.
႑Buffer vessel
There is a buffer vessel integrated in the heat pump that equalises the
temperature of the water that is sent out in the climate system.
႑Scheduling the indoor comfort and hot water
Heating and hot water as well as ventilation, can be scheduled for each
day of the week or for longer periods (vacation).
႑Large display 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.
