If a S is not present, or communication is lost with the S the controller shall operate using default modes and setpoints. Occupied Mode: uring occupied periods the supply fan shall run continuously and the outside air damper shall open to maintain minimum ventilation requirements. The chilled water and hot water valve shall modulate to maintain the active space temperature setpoint. Unoccupied Mode: When the space temperature is below the unoccupied heating setpoint of 60.0 deg. F (adj.), the supply fan shall start, the outside air damper shall remain closed and the hot water valve shall open. When the space temperature rises above the unoccupied heating setpoint of 60.0 deg. F (adj.) plus the unoccupied differential of 2.0 deg. F (adj.) the supply fan shall stop and the hot water valve shall close. When the space temperature is above the unoccupied cooling setpoint of 85.0 deg. F (adj.), the supply fan shall start, the outside air damper shall open if economizing is enabled and remain closed if economizing is disabled and the chilled water valve shall open. When the space temperature falls below the unoccupied cooling setpoint of 85.0 deg. F (adj.) minus the unoccupied differential of 4.0 deg. F (adj.) the supply fan shall stop, the chilled water valve shall close and the outside air damper shall close. Optimal Start: The S shall monitor the scheduled occupied time, occupied space setpoints and space temperature to calculate when the optimal start occurs. Morning Warm-Up Mode: uring 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 heating and supply fan. 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. Pre-ool Mode: uring optimal start, if the space temperature is above the occupied cooling setpoint, pre-cool mode shall be activated. When pre-cool is initiated the unit shall enable the fan and cooling or economizer. The outside air damper shall remain closed, unless economizing. When the space temperature reaches occupied cooling setpoint (adj.), the unit shall transition to the occupied mode. Optimal Stop: The S 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 ypass: The S 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 ontrol: ascade zone control shall be used in the occupied, occupied bypass, and occupied standby modes. It maintains zone temperature by controlling the discharge air temperature to control the zone temperature while minimizing the fan speed. 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.). Occupied Humidity ontrol: If the space relative humidity is greater than the humidity setpoint, the chilled water valve shall modulate to maintain space relative humidity and the reheat valve shall modulate to maintain the space temperature cooling setpoint. ehumidification mode shall terminate when the space relative humidity falls below the relative humidity setpoint minus the relative humidity offset. If the space relative humidity sensor fails the dehumidification sequence shall be terminated and an alarm shall be annunciated at the S. Economizer ontrol: Economizing shall be enabled when the outdoor air temperature is below the economizing enable setpoint of 65.0 deg. F (adj.). Economizing shall be disabled when the outdoor air temperature is greater than 5.0 deg. F above the economizer enable setpoint. When economizing is enabled the outside air damper shall modulate between the minimum damper position and 100% open to maintain the occupied cooling setpoint. If the outdoor air temperature sensor fails, economizing shall be disabled and an alarm shall be annunciated at the S. Supply Fan Operation: The supply fan shall cycle on demand during the unoccupied mode. When the controller is in the occupied mode, the supply fan shall operate continuously at the lowest minimum speed required to maintain space temperature. The supply fan status shall be monitored by the EM motor controller. If the supply fan fails the fan shall be commanded off and an alarm shall be annunciated at the S. manual reset shall be required to restart the fan. ondensate Overflow Monitoring: If the condensate level reaches the trip point, a condensate overflow diagnostic shall be annunciated at the S. To prevent the condensate drain pan from overflowing and causing water damage to the building the fan shall be disabled and the chilled water valve shall close.
