When setting the cool range it is important to limit the lowest cool set point, while it is not that important to limit the highest cool set point.
This is because the lower the cool set point, the colder the occupant can adjust the thermostat and the longer the unit will run cooling. While the high side allows the cool set point to be set higher, which means cooling will not run until the room reaches the higher setting.
We do not have an opinion on how you set this, but we are always available to assist.
