Set the minimum and maximum cool/heat temperature set points. This allows for onsite changes within a defined temperature range.

This is ideal for locations that want "flexible" restrictions and does not prevent your staff from making necessary onsite changes, if needed.

To set this up, follow these instructions.

Configure a pin that is required to make any changes to the thermostat locally.

This option is ideal for locations that want to prevent any changes on the thermostat, as much as possible. But be sure to write your pin down!

To set this up, follow these instructions.
