Symbio 700 - Low Leak Economizer 6-25 Ton
Summary:
This covers the installation of low leak economizers for 6 to 12.5 ton downflow units in the B and C cabinet (digit 39 = B, C). Symbio 700 supports a 0 to 100 percent economizer damper which requires a discharge air temperature sensor to be installed for economizer cooling. There are four configurable economizer types: fixed dry bulb, differential dry bulb, reference enthalpy, and comparative enthalpy.
