Fastener Torque Values

During free cooling operation, a supply air temperature (SAT) above 50_F will cause the dampers to modulate between Minimum Position setpoint and 100% open. With SAT from 50_F to 45_F, the dampers will maintain at the Minimum Position setting. With SAT below 45_F, the outside air dampers will be closed. When SAT rises to 48_F, the dampers will re-open to Minimum Position setting.

Should 100% outside air not be capable of satisfying the space temperature, space temperature will rise until Y2 is closed. The economizer control will call for compressor operation. Dampers will modulate to maintain SAT at 50 to 55_F concurrent with compressor operation. The Low Ambient Lockout Thermostat will block compressor operation with economizer operation below 42_F outside air temperature.

When space temperature demand is satisfied (thermostat Y1 opens), the dampers will return to Minimum Damper position if indoor fan is running or fully closed if fan is off.

If accessory power exhaust is installed, the power exhaust fan motors will be energized by the economizer control as the dampers open above the PE-On setpoint and will be de-energized as the dampers close below the PE-On setpoint.

Damper movement from full closed to full open (or vice versa) will take between 1-1/2 and 2-1/2 minutes.

Minimum Position setpoint for ventilation. If indoor fan is off, dampers will close. During Unoccupied mode operation, dampers will remain closed unless a DCV demand is received.

When the room temperature calls for heat (W1 closes), the heating controls are energized as described in Heating, Unit Without Economizer above.

Demand Controlled Ventilation

If a field-installed CO2 sensor is connected to the EconoMi$er IV control, a Demand Controlled Ventilation strategy will operate automatically. As the CO2 level in the space increases above the CO2 setpoint (on the EconoMi$er IV controller), the minimum position of the dampers will be increased proportionally, until the Maximum Ventilation setting is reached. As the space CO2 level decreases because of the increase in fresh air, the outdoor-damper will follow the higher demand condition from the DCV mode or from the free-cooling mode.

DCV operation is available in Occupied and Unoccupied periods with EconoMi$er IV. However, a control modification will be required on the 580J unit to implement the Unoccupied period function.

See Table 18 for torque values.
