SEQUENCE OF OPERATION 50TFQ004-012 Units energized and the position of the economizer damper will be determined by the supply-air temperature. Compressor no. 2 (50TFQ008-012) is locked out. When the second stage of cooling is satisfied, the compressor, RVS2, and outdoor-fan motor(s) will be deenergized. The damper position will be determined by the supply-air temperature. When the first stage of cooling is satisfied, the damper will move to fully closed position.
HEATING, UNITS WITH ECONOMIZER INCLUDING DURABLADE, ECONOMI$ER (Johnson) OR ECONOMI$ER2 (Sizes 008-012) — Upon a request for heating from the space thermostat, terminal W1 will be energized with 24 v. The IFC, outdoor-fan contactor (OFC), C1, and C2 will be energized. The reversing valves switch position and the indoor fan, outdoor fan, compressor no. 1, and compressor no. 2 are energized. The economizer damper blade opens to minimum position.
