is triggered on EVC that causes the calculation of the average value to start again.
The new start can be triggered through a manual switch cabinet by a check of the
system variable STARTUP. A switching table can implement the check of the
STARTUP point:
When STARTUP = 1, reset EVC to 1.
The controller sets STARTUP to zero during a network failure. After the return of the
network, STARTUP is 1 again. The switching table enables a new start of the OAT
calculation after a network failure.
NOTE: If the STARTUP variable triggers a reset of EVC, ensure that STARTUP is
reset to zero after running through the first cycle. See Appendix B for a
description of STARTUP reset.
