Carrier WeatherMaster Series Installation Instructions Manual

41Table 8 — Menu Structure* (cont)LEGEND* Table 8 illustrates the complete hierarchy. Your menuparameters may be different depending on your configuration.For example, if you do not have a DCV (CO2 ) sensor, thennone of the DCV parameters appear.† When values are displayed, pressing and holding the orbutton causes the display to automatically increment.** N/A = Not Applicable.†† ERV Operation: When in cooling mode AND the conditions areNOT OK for economizing, the ERV terminal will be energized.In the Heating mode, the ERV terminal will be energized whenthe OA is below the ERV OAT setpoint in the setpoint menu.*** When used with communicating actuator the damper out isreported in XX.X% open versus XX.X Vdc.††† After 10 minutes without a command or mode change, thecontroller will change to normal operation.NOTES:1. STATUS  OCCUPIED — The factory-standard Occupancysignal originates with a thermostat or other controller call forindoor fan operation at CTB terminal G. This signal passesthrough the Central Terminal Board’s OCCUPIED jumper JMP1to the ECONO connector and to the W7220’s OCC input termi-nal. An external timeclock or relay is required to implement anOccupancy schedule on the economizer damper position.2. STATUS  MA TEMP, SETPOINTS MAT SET — The W7220menu parameters and labels include designations MA, MAT andMixed Air for the economizer cooling control sensor. On these roof-top units, the economizer control sensor is located downstream ofthe evaporator/indoor coil in the supply fan section where this sen-sor is designated as Supply Air Temperature (SAT) sensor.3. SETPOINTS  DRYBLB SET — This point is not displayed if aReturn Air (differential) temperature sensor or an Outdoor Air en-thalpy sensor is connected.4.

Wait until the cali-bration is completed and the alarm will go away. Must have OA, MA andRA sensors for DCV calibration; set up in the Advanced setup menu.DA SENS ALM N/A N/A DISCHARGE AIR TEMPERATURE SENSOR ALARMDischarge air temperature is out of the range set in the ADVANCEDSETUP Menu. Check the temperature of the discharge air.SYS ALARM N/A N/A When AUX1-O is set to SYS and there is any alarm (e.g., failed sensors,etc.), the AUX1-O terminal has 24 Vac out.ACT UNDER V N/A N/A ACTUATOR VOLTAGE LOWVoltage received by actuator is below expected range.ACT OVER V N/A N/A ACTUATOR VOLTAGE HIGHVoltage received by actuator is above expected range.ACT STALLED N/A N/A ACTUATOR STALLEDActuator stopped before achieving commanded position.CLO — Compressor LockoutERV — Energy Recovery VentilatorLCD — Liquid Crystal DisplayMA — Mixed AirMAT — Mixed Air TemperatureN/A — Not ApplicableOA — Outdoor AirOAT — Outdoor Air TemperatureOCC — OccupiedRA — Return AirRAT — Return Air TemperatureRTU — Rooftop UnitSYS — System
