IntelliPTAC is a moisture proof PCBA with a combination of software, firmware and circuitry designed to optimize efficiency of operation of PTAC/PTHP units through intervening control of PTAC / PTHP system component activity. Subtle influences on system activity result in substantial savings in PTAC operating cost; usually about 10-15%.
PTAC/PTHP Control Panelsusually have buttons or dials to set the machine to condition the air in a room to a desired temperature. When the room reaches the temperature set point, the PTAC heat exchanger unit / cooling compressor cycles off.
The fan, however, continues to run for about sixty seconds. Studies show that PTAC / PTHP heat exchanger coils also retain energy after the compressor and fan rest. The heater remains hot or the coils remain cold and wet. It is the IntelliPTAC that initiates recovery of this otherwise wasted energy. The device works by extending the fan operation for a variable time period based on its assessment of current session activity. It takes advantage of system component heating/cooling energy that is, otherwise, lost.
