CURVE
The control computer shows the value for CURVE by means of a graph in the display. You
can set the heat curve by adjusting the CURVE value. The CURVE value indicated which
supply temperature the heating system is to have at an outdoor temperature of 0°C.
At outdoor temperatures colder than 0°C, supply water hotter than 40°C is sent out to the
heating system and at outdoor temperatures greater than 0°C, supply water cooler than
40°C is sent out.
