F1255PC – An excellent choice
F1255PC is part of a new generation of heat pumps, which have been in-
troduced to supply your home with inexpensive and environmentally
friendly heating and/or cooling. 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
distribution system. e.g. radiators, convectors or underfloor heating. It is
also prepared for connection to several different products and accessories,
e.g. extra hot water heater, ventilation recovery, pool and climate systems
with different temperatures.
An immersion heater of 4.5 kW can be connected automatically for
F1255PC-6 1x230V if anything unforeseen should occur or as backup op-
eration (then 3.5 kW).
For F1255PC-6 3x400V a 6.5 kW immersion heater can be connected
automatically if anything unforeseen should occur or as back-up operation
(then 3.5 kW).
F1255PC 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 thermo-
meters are not necessary.
Excellent properties for F1255PC:
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.
