Daikin AC launches a new economizer accessory for the FXMQ-P and FBQ series of ducted fan coils. The addition of an economizer allows mechanical compressor energy to be reduced under appropriate ambient conditions by introducing greater volumes of temperate outside air. The economizers utilize the Honeywell JADE economizer logic controls, allowing for simple, intuitive setup and installation. Single enthalpy control is standard with optional CO2 and dual (comparative) enthalpy control is available. Filtration options include MERV 8 and MERV 13 filters.
