The RedLink wireless controller from Mitsubishi Electric Cooling & Heating is now available for the company’s M-Series line of residential split-ductless and ducted cooling and heating systems. Previously available only with the light-commercial P-Series product line of split-ductless and ducted systems, the RedLink wireless controllers now provide increased zoning and temperature control capabilities to the residential M-Series line, according to the company. Introduced in 2011, the RedLink wireless controller communicates through radio frequency instead of infrared waves or wires. The manufacturer says this eliminates the need for electrical wires and enables the wireless controller to be placed in a different room than the indoor units. RedLink controllers are compatible with the Honeywell RedLink Internet Gateway, which allows users to control HVAC systems remotely through a Web browser, iPhone, iPad, Android or any Internet-enabled “smart” device.
