Danfoss – 43VUBMA102
Term Explanation
ROOM If ROOM shows 20°C the heat curve is not affected. If ROOM shows 
higher or lower, this indicates that the heat curve has been adjusted 
up or down to change the indoor temperature.
Heat transfer fluid 
circuit
The fluid circuit obtains heat/energy from the refrigerant circuit, 
which it then transports to the water tank or heating system. See 
the ”About your heat pump” section for further information.
Heat curve The control computer determines the correct temperature of the 
water to be distributed to the heating system based on the heat 
curve. The indoor temperature is adjusted by changing the gradient 
of the heating system’s CURVE.
