Unit Service Area Control Strategies
AHU1  Entire Building  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 74 degrees depending on outside air temperature and heat load in the area served. During "off" periods there will be an 83-degree upper limit and a 63-degree lower limit.
Rad    Radiator flow is started anytime outside temperatures are below 70 degrees
    Identify "last out lights off" person/process
    Set back domestic hot water temp to 120 degrees
