GLOSSARY Enhanced Commercial Controls 15.0 GLOSSARY Analog Control Signal Economizer Bypass An analog signal is a varying-voltage output signal, typically The Economizer Bypass provides energy conservation during between 0–10 volts. It is most often used to produce a specific operation of an ERV. It accomplishes this by sensing ambient amount of output from a variable-output device, such as a conditions and it then allows the return air stream to move digital scroll compressor or a variable speed fan. - Page 87 GLOSSARY Enhanced Commercial Controls NAND Memory Setpoint NAND flash memory is a type of non-volatile storage The desired value in a closed-loop feedback system, as in technology that does not require power in order to retain data. regulation of temperature or pressure.
