34SETPOINTSMAT SET 53F 38 to 65 F; incrementby 1SUPPLY AIR SETPOINTSetpoint determines where the economizer will modulate the OA damperto maintain the mixed air temperature.LOW T LOCK 32F -45 to 80 F;increment by 1COMPRESSOR LOW TEMPERATURE LOCKOUTSetpoint determines outdoor temperature when the mechanical coolingcannot be turned on. Commonly referred to as the Compressor lockout.DRYBLB SET 63F 48 to 80 F; incrementby 1OA DRY BULB TEMPERATURE CHANGEOVER SETPOINTSetpoint determines where the economizer will assume outdoor air tem-perature is good for free cooling; e.g.; at 63 F unit will economize at 62 Fand below and not economize at 64 F and above. There is a 2 F dead-band.ENTH CURVE ES3 ES1,ES2,ES3,ES4, orES5ENTHALPY CHANGEOVER CURVEEnthalpy boundary “curves” for economizing using single enthalpy.DCV SET 1100ppm 500 to 2000 ppm;increment by 100DEMAND CONTROLLED VENTILATIONDisplays only if CO 2 sensor is connected. Setpoint for Demand ControlledVentilation of space. Above the setpoint, the OA dampers will modulateopen to bring in additional OA to maintain a space ppm level below the set-point.MIN POS 2.8 V 2 to 10 Vdc VENTILATION MINIMUM POSITIONDisplays ONLY if a CO 2 sensor is NOT connected.VENTMAXWith 2-speed fan units VENT-MAX L (low speed fan) andVENTMAX H (high speed fan)settings are required2.8 V2 to 10 VdcDCV MAXIMUM DAMPER POSITIONDisplays only if a CO 2 sensor is connected.
