Smart Air Conditioning & Heat Pump Interfaces
Smart air conditioning interfaces connect an existing air conditioning system to a building management system. Every manufacturer uses its own proprietary control bus, so a Daikin, Mitsubishi Electric or Toshiba unit cannot be read or controlled by a BMS on its own. The interface wires into the unit exactly where a manufacturer's wall controller would sit and presents it on an open protocol such as BACnet, Modbus or KNX, giving your head end full visibility of setpoint, mode, fan speed, room temperature and fault status.
Our range covers domestic, commercial and VRF systems from all the major manufacturers, in both BACnet/IP and MS/TP and Modbus RTU variants, along with a universal infrared model for units without a wired connection.
Air conditioning interfaces are most often specified where a building already has working air conditioning plant that sits outside the control of the BMS. Rather than replacing serviceable equipment, the interface brings it onto the same network as the heating, ventilation and lighting so it can be scheduled, setpoint limited and monitored centrally. Typical applications include offices and commercial fit outs where split and VRF systems have been installed piecemeal over the years, retail and hospitality estates that need consistent control across multiple sites, schools and healthcare buildings where out of hours running is a significant cost, and any refurbishment where the mechanical plant is staying but the controls are being upgraded. The result is lower energy consumption from enforced schedules and setpoint limits, faster fault response through alarms reported straight to the BMS, and reliable runtime data for energy reporting, all at a fraction of the cost of a manufacturer's own centralised control system.
