Unit Service Area Control Strategies
AHU1  Basement, 1st, 2nd floor Labs  Thermostat set at 70-degrees all year. Cooling controlled by a duct temperature sensor for 76-degree return air. Heating controlled by thermostat and reheat coils in VAV boxes. Room temperature will naturally fluctuate between 70 degrees and 76 degrees depending on outside air temperature and heat load in the area served. During “off” periods there will be an 80-degree upper limit and a 65-degree lower limit.
AHU2  1st and 2nd floor Offices and Labs  Thermostat set at 70-degrees all year. Cooling controlled by a duct temperature sensor for 76-degree return air. Heating controlled by thermostat and reheat coils in VAV boxes. Room temperature will naturally fluctuate between 70 degrees and 76 degrees depending on outside air temperature and heat load in the area served. During “off” periods there will be an 80-degree upper limit and a 65-degree lower limit.
