Mitsubishi Electric Cooling & Heating will now incorporate Honeywell’s energy-saving RedLink wireless HVAC protocol into its line of split-ductless and ducted heat pumps. RedLink’s wall-mounted remote control communicates via radio frequency; controllers can be placed in different rooms without requiring wires to be run through walls. Back-lit displays allow users to control up to 16 zones. Functions include adjustable fan speed, vane positioning, and zone control.
