OVERFOW BI BO ODU - 1 DX STG 1 BO AO BI Sequence of Operations DX Split 1 ~ 43 Flow Building Automation System Interface: The Building Automation System (BAS) shall send the controller Occupied Bypass, Morning Warm-up / Pre-Cool, Occupied / Unoccupied and Heat / Cool modes. If a BAS is not present, or communication is lost with the BAS the controller shall operate using default modes and setpoints. Occupied Mode: During occupied periods the supply fan shall run continuously and the outside air damper shall open to maintain minimum ventilation requirements. The DX cooling and heating modes shall operate accordingly to maintain the active space temperature setpoint. Optimal Start: The BAS shall monitor the scheduled occupied time, occupied space setpoints and space temperature to calculate when the optimal start occurs. Morning Warm-Up Mode: During optimal start, if the space temperature is below the occupied heating setpoint a morning warm-up mode shall be activated. When morning warm-up is initiated the unit shall enable the heat pump mode. The outside air damper shall remain closed. When the space temperature reaches the occupied heating setpoint (adj.), the unit shall transition to the occupied mode. Optimal Stop: The BAS shall monitor the scheduled unoccupied time, occupied setpoints and space temperature to calculate when the optimal stop occurs. When the optimal stop mode is active the unit controller shall maintain the space temperature to the space temperature offset setpoint. Occupied Bypass: The BAS shall monitor the status of the on and cancel buttons of the space temperature sensor. When an occupied bypass request is received from a space sensor, the unit shall transition from its current occupancy mode to occupied bypass mode and the unit shall maintain the space temperature to the occupied setpoints (adj.). Space Temperature Control: The space temperature shall be maintained between the occupied cooling setpoint of 74.0 deg. F (adj.) and the occupied heating setpoint of 71.0 deg. F (adj.). The unit shall transition to the cooling mode when the space temperature rises one degree above the occupied cooling setpoint of 74.0 deg. F (adj.). The unit shall transition to the heating mode when the space temperature drops one degree below the occupied heating setpoint of 74.0 deg. F (adj.). Condensate Overflow Monitoring: If the condensate level reaches the trip point, a condensate overflow diagnostic shall be annunciated at the BAS. To prevent the condensate drain pan from overflowing and causing water damage to the building the fan shall be disabled and the DX cooling shall be disabled. Filter Timer: The fan-run time (hrs) shall be compared to the filter maintenance timer setpoint. Once the setpoint is reached a filter timer alarm diagnostic shall be annunciated at the BAS. When the diagnostic is cleared, the filter-maintenance timer is reset to zero, and the timer begins accumulating fan-run time again. STATE OF EXAS HUGO H.

If a BAS is not present, or communication is lost with the BAS the controller shall operate using default modes and setpoints. Optimal Start: The BAS shall monitor the scheduled occupied time, occupied space setpoints and space temperature to calculate when the optimal start occurs. Occupied Bypass: The BAS shall monitor the status of the on and cancel buttons of the space temperature sensor. When an occupied bypass request is received from a space sensor, the unit shall transition from its current occupancy mode to occupied bypass mode and the unit shall maintain the space temperature to the occupied setpoints (adj.). Heat/Cool Mode: When the space temperature rises above the occupied cooling setpoint the mode shall transition to cooling. When the space temperature falls below the occupied heating setpoint the mode shall transition to heating. When the space temperature is above the occupied cooling setpoint or below the occupied heating setpoint the mode shall remain in its last state. If the space temperature sensor fails the mode shall remain in its last state and an alarm shall be annunciated at the BAS. If the local and communicated setpoints fail the controller shall disable the supply fan and an alarm shall be annunciated at the BAS. Supply Air Temperature Reset Control: On a rise in space temperature (+2.0 deg. F adj. or greater) above the space cooling setpoint (74.0 deg. F adj.); the supply fan speed shall modulate from minimum (50% adj.) to maximum (or design) air flow to maintain space cooling temperature setpoint while keeping the discharge air temperature setpoint at minimum (55.0 deg. F adj.). As space temperature decreases below 76.0 deg. F (space cooling setpoint 74.0 deg. F deg. F); the fan speed shall be locked at minimum air flow and the discharge air temperature setpoint remains at minimum. When space temperature decreases to 75.0 deg. F (cooling setpoint of 74.0 deg. F adj deg. F) or below for a period of time (default 1 min. adj.); the fan speed shall remain at minimum, the discharge air temperature setpoint remains at minimum, and control enters into discharge air temperature setpoint reset mode. As space temperature continues to drop below 75.0 deg. F (space temperature cooling setpoint deg. F); the fan speed shall remain at minimum and the discharge air temperature setpoint shall be reset from minimum (55.0 deg. F adj.) to maximum (65.0 deg. F adj.) as space temperature drops from 75.0 deg. F to 74.0 deg. F to maintain the space cooling temperature setpoint. On a continued drop of space temperature below the space cooling temperature setpoint (74.0 deg. F adj.) through (71.0 deg. F adj.) the space temperature control shall be within its deadband; the fan speed remains at minimum and discharge air setpoint of (65.0 deg. F adj.) for cooling. As space temperature decreases to the heating setpoint (71.0 deg. F adj.) the control shall switch to the heating discharge air temperature reset. In the heating mode, the staged heat will be enabled; the supply fan shall remain at minimum air flow and the discharge air temperature setpoint shall be reset from 70.0 deg. F to 90.0 deg. F as the space temperature drops from 71.0 deg. F to 70.0 deg. F. As space temperature continues to decrease to heating setpoint (71.0 deg. F adj.) deg. F; the discharge air temperature setpoint shall remain at maximum (90.0 deg. F adj.), the fan shall be modulated from minimum to maximum air flow to maintain the space temperature heating setpoint. When the space temperature increases the reverse control shall be implemented. Occupied Humidity Control: If the space relative humidity is greater than 50% (adj.), the DX cooling shall stage to maintain space relative humidity setpoint of 50% (adj.) and the electric heat shall stage to maintain the discharge air temperature setpoint. Mode shall terminate when the space relative humidity falls below the relative humidity setpoint of 50% (adj.) minus 3% (adj.). If the space relative humidity sensor fails, the dehumidification sequence shall be terminated and an alarm shall be annunciated at the BAS. Supply Fan: The supply fan shall be enabled while in the occupied mode and cycled on during the unoccupied mode. The unit controller shall vary the supply fan speed to optimize minimum fan speed in all cooling and heating modes. A differential pressure switch shall monitor the differential pressure across the fan. If the switch does not open within 30 seconds after a request for fan operation a fan failure alarm shall be annunciated, the unit shall stop, requiring a manual reset. Filter Status: A differential pressure switch shall monitor the differential pressure across the filter when the fan is running. If the switch closes during normal operation a dirty filter alarm shall be annunciated at the BAS. Automatic Shutdown Control: Upon detection of smoke at any of the duct mounted S.D. (furnished, installed, and wired for shutdown by division 26), motor shall be de-energized. Upon detection of air below 36 deg., the freeze stat shall de-energize the ahu motor and cause the outside air damper to close fully. Outside Air Damper: The Outside air damper shall open and close when cooling is initiated. Checked By: Scale: STATE OF EXAS HUGO H.
