Flow Temp. Setpoint: Flow temperature for the heat-
ing circuit
Flow Temp. VF2: Current flow temperature VF2.
C4
°mins lag/gain: The °mins lag/gain is the sum of the
41 °C
difference between TARGET flow temperature
29 °C
and ACTUAL flow temperature per minute. The
OFF heat pump starts at a particular heat deficiency
(see energy balance control (¬ Ch. 9.4.2)).
Open
Status of pump: Indicates whether the pump is
