No. A 75F system will act standalone without a connection to the internet. However, you will lose the following:
- Remote support from 75F
- Over-the-Air updates
- Ability to use Facilisight for remote diagnostics, site monitoring, schedule changes, space temperature adjustments, remote alerts via text, email or push notifications, and data storage/history.
- "Replace CCU" feature.
Note: An internet connection is required during the registration process for each CCU. The CCUs will automatically update to the most current version during the registration process and will set up a building on Facilisight in case the customer can connect to the internet down the road.
