Goals and Symptoms
CM3000 Power Demand and Peak Demand are resetting on the 1st of the month when no scheduled tasks are set up.
Causes and Fixes
CM3000s with firmware 15.020 and below will experience this issue.
Register 6426 has a default setting to automatically reset peak demand at the beginning of the month. The default has been set to 3 to reset both power and input metering peak demand.
To stop demand from resetting each month:
Change the default value from 3 to 0:
write value 9020 to register 8000
write value 0 to register 6426
write value 1 to register 8001
write value 9021 to register 8000
