706-FFS and 706-HPFS

The 706-FFS and 706-HPFS controllers optimize the flow of air of typical constant volume heating and air conditioning equipment. Its function measures system efficiency, improves comfort and indoor air quality all at the same time.

By optimizing (varying) the flow of air before and after each cycle, more usable energy is recovered by expelling all of the energy of the cycle, mixing it with otherwise destratified air and delivering it to the space as usable energy, all at a varying flow rate.

The result of this shortens the "on time" and/or increases the length of the "off cycle", saving energy while maintaining even floor to ceiling temperatures.
