SYSTEM ENGINEERING GUIDE 63-2484—03 Solid State Economizer System (CONSISTING OF: C7046C DISCHARGE AIR SENSOR OR C7150B MIXED AIR SENSOR, C7400 SOLID STATE ENTHALPY SENSOR OR C7660 SOLID STATE TEMPERATURE SENSOR, M7415, M7215 OR M8405 DAMPER ACTUATORS OR MODU- LATING DIRECT COUPLED ACTUATORS (MS7503 or MS7505) T6031H THERMOSTAT AND W7459 OR W7212 SOLID STATE ECONOMIZER LOGIC MODULE) APPLICATION The Solid State Economizer System provides an economical method of providing cooling air by incorporating outdoor air in the first stage of cooling in heating, ventilating and air conditioning (HVAC) systems. The Solid State Economizer System consists of the C7046C Discharge Air Sensor or C7150B Mixed Air Sensor, C7400 Solid State Enthalpy Sensor or C7660 Solid State Temperature Sensor, M7215, M7415 or M8405 Damper Actuators or Modulating Direct Coupled Actuators (MS7503 or MS7505), T6031H Thermostat and W7212A,C or W7459A,C Solid State Economizer Logic Module. FEATURES C7046C Discharge Air Sensors have probe lengths of 8 in. (203 mm) and nominal sensor resistance of 3000 ohms at 77°F (25°C). • No setting or calibration required. • Solid state components not affected by dust or dirt. • Fast reacting. • Rugged aluminum insertion probe. C7150B Mixed Air Sensor is used with the W7212/W7459 Economizer Module to sense mixed or discharged air in roof- top packaged air conditioning equipment. • No setting or calibration required. C7400 Solid State Enthalpy Sensor and C7660 Solid State Temperature Sensors are used with the W7212/W7459 Solid State Economizer Logic Module to sense outdoor and return air enthalpy or temperature. • C7400 senses and combines temperature and humidity (enthalpy) of outdoor air (heat index). • C7660 senses temperature only and can only be used in single referential control. Use C7400 enthalpy for differential control. • When enthalpy/temperature of outdoor air increases, the outdoor air damper closes to a preset minimum position. • When enthalpy/temperature of outdoor air is low, the outdoor air damper opens to reduce the building cooling load.
