Mode = Operating mode (0 = summer)
SPC1 = Summer LB setpoint
PC11 = Type of control (0 = Lateral band)
PC12 = Proportional band
PC21 = Lower limit chiller setpoint
PC22 = Upper limit chiller setpoint
Vice versa, in the winter operating mode (heat pump), the entire band is moved below the setpoint:
Mode = Operating mode (1 = winter)
SPH1 = Winter setpoint LB
PC11 = Type of control (0 = Lateral band)
PC12 = Proportional band
PC23 = Lower limit heat pump setpoint
PC24 = Upper limit heat pump setpoint
8.6.2 Zero energy band (ZEB) Control
This type of control requires definition of a zero energy band (ZEB) around the set point. In the zero energy band, the compressors will
not be turned on or turned off.
If the output temperature of the AF is outside the zero energy band, the compressors activate/deactivate to bring the output
temperature of the AF within the zero energy band.
The switch-on/switch-off requests for the various power steps provided by the compressors in the summer operating mode (chiller)
follow this logic:
Switch-on: when the output temperature of the AF exceeds the zero energy band.
Switch-off: when the output temperature of the AF falls back within the zero energy band.
Mode = Operating mode (0 = summer)
SPC1 = Summer setpoint NZ
PC11 = Type of control (1 = zero energy band)
PC 14 = Zero energy band
PC17 = Extra time for outside zone request
PC21 = Lower limit chiller setpoint
PC22 = Upper limit chiller setpoint
