In efficiency class C, the difference the temperature setpoints for heating and cooling is very small at
ca. 1 K (minimum dead energy band). Operation of the HVAC plant starts two hours prior to
occupancy and ends three hours after the end of the occupancy period.
BAC efficiency class B
Efficiency class B applies better adapted operating times by optimizing switching on/off periods. The
current temperature setpoints for heating and cooling are monitored by superposed functions,
resulting in a dead energy band that is greater than the one for efficiency class C.
BAC efficiency class A
Efficiency class A provides additional energy efficiency by applying advanced BAC and TBM
functions as well as adaptive setpoint adjustments for cooling or demand-controlled air flows.
