This keyword is used to describe a series of stationary simulations with different loads and durations. This results in an accumulated heat consumption, heat production and operating costs for heat production and pump operation.

Where:
durM : Duration in hours, the N:th period.
TmpN : Ground temperature in ? C for the N:th period.
fqN(M) : Load factor for node type M applicable to the N:th period.
fdtN(M) : Temperature factor for node type M applicable to the N:th period.
tiN(M) : Inlet temperature for node type M applicable to the N:th period.
rtN(M) : Change in return temperature for node type M applicable to the N:th period.
prN(M) : Production cost for node type M applicable to the N:th period.
