The control unit’s operating modes
When a heat pump is installed, it must be set-up for a specifi c operating
mode. An operating mode relates to the heat pump’s working situation
which is dependent on the prevailing conditions, for example, whether an
electric or oil-fi red boiler is to be connected.
It is the task of the installer to adjust the heat pump with the correct
settings for the relevant operating mode and other conditions.
Heat pump with electric cassette
When the heat pump is used with one (or two) electric cassettes, the control
unit in the control cabinet sets itself for this operation. This means that the
heat pump works with additional heat from the electric cassette and that hot
water is produced in an external hot water heater, if connected. A sensor
located on the outside of the house sends information about the outdoor
temperature to the control unit. The control unit controls heating and hot
water production based on the read off current values and the set values.
Heat pump with mixed additional heat, e.g. an
existing electric/oil-fi red boiler.
When the heat pump is used with an existing electric/oil-fi red boiler, the
control unit in the control cabinet sets itself for this operation. This means
that the heat pump works with additional heat from the electric/oil-fi red
boiler and that hot water is produced in an external hot water heater, if
connected. A sensor located on the outside of the house sends information
about the outdoor temperature to the control unit. The control unit controls
heating and hot water production based on the read off current values and
the set values.
Heat pump with electric boiler 290 A/W
(Optima 600-1100)
When the heat pump is used with 290 A/W, the control unit sets itself for
this operation. This means that the heat pump operates with additional heat
from the electric boiler and that the hot water is produced in the electric
boiler’s hot water heater. A sensor located on the outside of the house
sends information about the outdoor temperature to the control unit. The
control unit controls heating and hot water production based on the read off
current values and the set values.
