In case the main circuit breaker does not provide enough capacity to run all electrical appliances in parallel, it is possible to set priorities for outputs and the output module will make sure the total load is not exceeded. This enables to use a lower capacity main circuit breaker and save on fees to the electricity provider.
1. Go to Menu → Devices → 12DO Module and set the outputs to PWM on digital output
2. Click Add new group
3. Set Total resources - maximum Watts for the main circuit breaker
4. Add new output and set its consumption in Watts
5. Sort the outputs by priorities. The highest priority output shall be on top.
The output module will only switch on combinations of outputs where the sum of their loads does not exceed Total resources.
