REFER TO AHU SCHEDULES FOR MULTIPLE VFDS FOR SUPPLY & RETURN FAN ARRAYS. �THE PROPERTY OF THE ARCHITECTS AND C. AHU DISCHARGE AIR TEMPERATURE CONTROL: MAY NOT BE USED WITHOUT PRIOR NOTES: CONSENT FROM THE ARCHITECT 1. THE ECONOMIZER DAMPER AND DX COOLING SYSTEM ARE CONTROLLED IN SEQUENCE TO MAINTAIN 1. REFER TO SPECIFICATIONS FOR ADDITIONAL REQUIREMENTS. THE DISCHARGE AIR TEMPERATURE (DAT) SETPOINT; INITIAL SETPOINT IS 56 F. THE SYSTEM SHALL RUN A QUERY EVERY 10 MINUTES TO DETERMINE WHETHER THE SETPOINT SHOULD BE INCREASED REVIEW , OR DECREASED. DAT SHALL BE RESET BETWEEN 52F AND 60F AS DESCRBED BELOW. 2. DECREASE DAT-IF THE ASSOCIATED ZONE TEMPERATURE IS 2F OR MORE ABOVE SETPOINT THEN REV. DATE DESCRIPTION DECREASE THE DAT BY 1 F. 3. INCREASE DAT-IF THE ASSOCIATED ZONE TEMPERATURE IS 2F OR MORE ABOVE SETPOINT THEN O�'J ZC SCHEMATIC DESIGN WCREASE THE DAT BY 1 F. 4. DURING HEATING, THE ECONOMIZER DAMPERS ARE POSITIONED TO MWfMUM OUTDOOR AIR. DURING O8 � 'rJ" PROGRESS DRAWINGS COOLING, THE ECONOMIZER DAMPERS AND DX COOLWG ARE CONTROLLED IN SEQUENCE TO MEET THE COOLfNG REQUIREMENT. O9 OS PERMIT SET 5. ENABLE THE ECONOMIZER WHEN THE OUTSIDE AIR TEMPERATURE IS LESS THEN OR EQUAL TO THE � RETURN AIR TEMPERATURE MINUS 2F. DISABLE THE ECONOMIZER WHEN THE OUTSIDE AIR TEMPERATURE IS GREATER THEN OR EQUAL TO THE RETURN AIR TEMPERATURE PLUS 2F. D. MINIMUM OUTDOOR AIR: FLOW IS MAINTAINED AT A CONSTANT VALUE BY MODULATION OF THE OUTDOOR AIR DAMPER. MINIMUM OUTDOOR AIRFLOW SETPOINT IS (NDICATED ON THE EQUIPMENT SCHEDULES. � E. ZONE TEMPERATURE CONTROL 1. ZONE TEMPERATURE SETPOINTS SHALL BE 70F FOR HEATING AND 75F FOR COOLING DURING M ECH AN I CAL LEGEN D O(. OCCUPIED TIME PERIODS AND 60F FOR HEATING AND 85F FOR COOLING DURING UNOCCUPIED TIME PERIODS FOR ENERGY SAVINGS. RESET ALL UNOCCUPIED SETPOINTS TO OCCUPIED SO ZONE IS UP GEN ER AL N OTES TO TEMPERATURE PRIOR TO OCCUPANCY. G. EXHAUST FAN: THE TWO POSITION CONTROL DAMPER SHALL OPEN FULLY PRIOR TO FAN START-UP. H. BUILDING RELIEF AIR DAMPER: SHALL BE INTERLOCKED WITH THE RTU OPERATION. DAMPER IS OPEN WHEN ANY RTU IS IN OCCUPIED MODE AND CLOSED WHEN THE RTUS ARE IN UNOCCUPIED, MORNING WARMUP OR COOLDOWN MODES. � • �
