System description
Principle of operation
F2025 is an air/water heat pump, specially designed for the
Nordic climate. F2025 utilises the outside air so there is no
need for bore holes or coils in the ground. F2025 has an
automatic 2-stage capacity control of the fan (does not apply
to F2025-6 kW, which only has one fan speed).
F2025 is designed for **water based heating systems and
can be used together with most electric boilers, oil-fired
boilers or equivalent. The heat pump includes an advanced
control system for optimal control. F2025 is started by a start
signal from another controller or thermostat.
F2025 can also be controlled by a specially designed control-
ler, SMO 10 *. This connects and disconnects the additional
heat and controls switching between room heating and hot
water heating.
Accessories such as extra shunt group and pool control can
be connected if SMO 10 is present.
F2025 can both heat hot water effectively at high outdoor
temperatures and give a high output to the heating system
at low outdoor temperatures.
If the outdoor temperature drops to a level below the stop
temperature all heating must then occur with external addi-
tional heat.
F2025 is manufactured in four sizes: 6, 8, 10 and 14 kW.
The material has been chosen for a long service life and is
designed to withstand the Nordic outdoor conditions.
