Set Points
The following parameters are remembered during power off (permanent memory), are factory set to the Default value, and can be
adjusted to any value in the Range column. Read and write access to these set points is determined by the Global HMI (Human
Machine Interface) Standard Specification.
Unit Level Set Points
All of these settings require the unit switch to be off in order to make a change and require rebooting the controller in order to apply
a change.
