Electrical fault. Contact your
installer.
ERR PHASE
SEQ.
The compressor in the heat
pump is operating in the
wrong direction and this means
that only the auxiliary heater is
maintaining heating.
The phase
sequence changed
when changes
were made in the
electrical installa-
tion of the house.
Contact your
installer.
HIGH RETURN The temperature of the water
that returns from the radiators
is too high and prevents the
heat pump from working.
Insufficiently
opened radiator/
floor loop thermo-
stats.
Ensure that all
thermostat valves
are fully open.

Term Explanation
Evaporator In the evaporator, energy from the heat source is absorbed by the
refrigerant passing through the evaporator. The refrigerant turns
into gas. (See the “About your heat pump” section for further infor-
mation).
INTEGRAL INTEGRAL is the heating system’s energy balance. Heat generation
is controlled by a calculated requirement. This value is determined
by comparing the actual supply temperature with its calculated
supply temperature. The difference between the temperatures is
multiplied by the time during which the difference is active. The
resulting value is referred to as the integral. The integral value is
automatically established when the heating system is in use. The
value of the integral can be viewed in the display under the sub-
menu TEMPERATURE.
Compressor The compressor raises the temperature and pressure of the refriger-
ant. (See the “About your heat pump” section for further informa-
tion).
Condenser In the condenser, the refrigerant supplies its heat energy to the
heat transfer fluid circuit. (See the “About your heat pump” section
for further information).
CURVE The CURVE value is set via the display. The set value indicates the
supply temperature of the water that is transported to the radiators
at an outdoor temperature of 0°C.
Brine Is a water based mixture that transports energy from the heat
source to the heat pump. (See the “About your heat pump” section
for further information).
