The VRF problem CoolAutomation solves

VRF and mini-split systems are excellent equipment with a well-known weakness: each manufacturer ships its own closed controls ecosystem. Put Daikin on one floor and Mitsubishi on another and you now have two systems, two interfaces, and no single view of the building. Your BMS — the one running everything else — can't see either of them.

CoolAutomation exists to close that gap. Its integration devices sit between VRF equipment and the outside world, translating proprietary manufacturer protocols into something a BMS, a home automation platform, or a cloud service can actually use. The company now supports over 10,000 customers across 50,000+ sites in 100+ countries, with 20+ compatible HVAC brands and 30+ home automation integration partners.

Integration devices

• CoolMaster — the core product line for professional VRF and multi-split integration into building management systems.
• CoolMaster EDGE — adds edge processing at the device, so logic and data handling happen locally rather than depending on a cloud round trip.
• CoolPlug — purpose-built for split and mini-split systems, bringing individual units into the same control layer.
• CooLinkBridge — integration for zone controllers and heat pumps.
• CoolMasterLT and CoolMaster Home — lighter-weight options for smaller installations and residential-scale integration.

Cloud applications

Once the equipment is connected, CoolAutomation's cloud layer is where the operational value shows up:

• HVAC predictive maintenance — early anomaly detection, so a failing compressor surfaces as a trend before it surfaces as a tenant complaint.
• Advanced HVAC operations — remote, multi-site control and monitoring from one place.
• VRF power distribution — apportioning VRF energy use by unit for accurate tenant billing, which is often the single feature that pays for the integration in a multi-tenant building.
• HVAC control app — a straightforward interface for occupants and facility staff.
• Developer API — for pulling HVAC data into whatever platform you already run.

What owners actually get out of it

CoolAutomation reports energy savings of up to 30%, and customers cite roughly 50% fewer on-site service visits once remote diagnostics are in place. That second number is the one facility managers tend to care about: a technician who can read fault codes and system state remotely resolves a large share of calls without a truck roll, and arrives with the right part when a visit is genuinely needed.

How we use CoolAutomation

We're most often deploying CoolAutomation in one of three situations:

• A building has VRF from one manufacturer and a BMS from another, and the owner wants one interface instead of two.
• A multi-tenant property needs defensible VRF energy allocation for billing.
• A portfolio of small sites needs central visibility without a full BAS at every location.

In each case the point is the same: unify the VRF fleet with the rest of the building, with no proprietary lock-in. Paired with our Alerton, Niagara, or Distech work, CoolAutomation is usually the last piece that makes a building genuinely single-pane.
