4.4.1 Internal add. heat
The internal additional heat has three steps, E2.E1 (4.5
kW), E2.E2 (4.5 kW) and E2.E3 (6.75 kW). When all
stages are connected a total of 15.75 kW is obtained. A
degree minute calculation is used to activate each stage.
E2.E1: The compressor is running and E11.T1 does not
reach its set point value. Calculation of difference
between E11.T1 set point value – set Hysteresis (3 K)
and E11.T1 actual value are added continuously. When
the sum reaches the value set in Delay (180 °min) stage
1 is activated.
