SEQUENCE OF OPERATION
TERMINAL UNIT CONTROLLER RECEIVES SIGNAL FROM BUILDING CONTROLLER WHICH INITIATES OCCUPIED OR UNOCCUPIED MODE. DURING UNOCCUPIED MODE SPACE TEMPERATURE RESET TO UNOCCUPIED SETPOINTS AND DURING OCCUPIED MODE SPACE TEMPERATURE RESET TO OCCUPIED SETPOINTS. WHEN ENTERING OCCUPIED MODE, USE AN OPTIMAL START ALGORITHM FOR WARM-UP OR COOL-DOWN. MINIMIZE THE WARM-UP OR COOL-DOWN PERIOD WHILE STILL ACHIEVING COMFORT CONDITIONS BY THE START OF SCHEDULED OCCUPIED PERIOD.
UNOCCUPIED MODE:
CLOSE DAMPER, SHUT OFF FAN, AND DISABLE ELECTRIC HEATER. IGNORE ANY SIGNALS FROM SPACE CARBON DIOXIDE SENSORS.
IF SPACE TEMPERATURE IS GREATER THAN UNOCCUPIED COOLING SETPOINT, AND IF CENTRAL AIR HANDLING UNIT SUPPLY FAN IS RUNNING, MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM COOLING AIRFLOW SETPOINTS TO MAINTAIN SPACE TEMPERATURE AT UNOCCUPIED COOLING SETPOINT.
IF SPACE TEMPERATURE IS LESS THAN UNOCCUPIED HEATING SETPOINT, MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM HEATING AIRFLOW SETPOINTS AND MODULATE ELECTRIC HEAT TO MAINTAIN SPACE TEMPERATURE AT UNOCCUPIED HEATING SETPOINT.
OCCUPIED MODE:
MODULATE DAMPER TO MAINTAIN MINIMUM AIRFLOW SETPOINT AND DISABLE ELECTRIC HEATER.
IF SPACE TEMPERATURE IS GREATER THAN OCCUPIED COOLING SETPOINT, MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM COOLING AIRFLOW SETPOINTS TO MAINTAIN SPACE TEMPERATURE AT OCCUPIED COOLING SETPOINT.
IF SPACE TEMPERATURE IS LESS THAN OCCUPIED HEATING SETPOINT, MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM HEATING AIRFLOW SETPOINTS AND MODULATE ELECTRIC HEAT TO MAINTAIN SPACE TEMPERATURE AT OCCUPIED HEATING SETPOINT.
FOR ZONES EQUIPPED WITH CO2 SENSORS (SEE PLANS): IF SPACE CO2 CONCENTRATION IS GREATER THAN 900 PPM (ADJ.) MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM COOLING AIRFLOW SETPOINTS TO MAINTAIN CONCENTRATION AT SETPOINT. MODULATE ELECTRIC HEAT AS NECESSARY TO MAINTAIN SPACE TEMPERATURE. WHEN ZONE CO2 CONCENTRATION DROPS BELOW 800 PPM, RESUME NORMAL TEMPERATURE MAINTENANCE OPERATION. ALARM THE BAS IF CO2 LEVELS EXCEED 1300 PPM (adj.).
WARM-UP MODE:
TERMINAL UNIT RECEIVES GLOBAL SIGNAL FROM BUILDING CONTROLLER TO INITIATE WARM-UP MODE. DURING WARM-UP MODE DISABLE ELECTRIC HEATER AND MODULATE DAMPER BETWEEN MINIMUM AND MAXIMUM AIRFLOW SETPOINTS TO MAINTAIN SPACE TEMPERATURE AT OCCUPIED HEATING SETPOINT.
