siteConnect CS

Sharing operational data using our siteConnect™ Platform provides greater visibility into your HVAC, BAS, and EMS systems, leading to better control over your equipment. A two-way data flow enables full access to our analytic software as well as the HVAC equipment from all your locations.

For example, the facility manager can check on the chiller from home first thing in the morning and the service provider can remotely troubleshoot the system down to the individual components. Corrective actions can be implemented much faster as the service provider can begin troubleshooting and ensure technicians are fully aware of the related issue prior to arriving at the site.
