The Bromic Smart-Heat App will guide you through the installation process, step by step to configure each controller. Before you commence the installation, a little planning is required to define how to setup the heaters within the App. Sites are created to group heaters and separate site control. You can have all heaters on one site, accessible to all users or split the heaters into groups allocated to different sites. Sites function to separate user access if this is required by inviting users to each site independently (by the site admin user.)
