NOTES:
If avg kW value>0, avg positive kW = avg kW, avg negative kW = 0
If avg kW value<0, avg negative kW = avg kW , avg positive kW = 0)
System Maximum Power Draw (kW System Max)
system highest instantaneous power draw since reset, in kW (resettable)
= max kW net value, signed, BACnet
= positive max KW value, signed, BACnet
= negative max kW value, signed, BACnet
= max kW value, unsigned
= positive max kW value, unsigned
= negative max kW value, unsigned
NOTES:
If max kW value>0, max positive kW = max kW, max negative kW = 0
If max kW value<0, max negative kW = max kW , max positive kW = 0

System Minimum Power Draw (kW System Min)
system lowest instantaneous power draw since reset in kW (resettable)
= min kW net value, signed, BACnet
= positive min kW value, signed, BACnet
= negative min kW value, signed, BACnet
= min kW value, unsigned
= positive min kW value, unsigned
= negative min kW value, unsigned
NOTES:
If min kW value>0, min positive kW = min kW, min negative kW = 0
If min kW value<0, min negative kW = min kW , min positive kW = 0
