Unit Service Area Control Strategies
AHU1  Ground Flr and 1st Flr East  Digital thermostat set at 73-degrees all year.

During “off” periods there will be an 83-degree upper limit and a 63-degree lower limit.
AHU2  1st Flr West  Digital thermostat set at 73-degrees all year. 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 83-degree upper limit and a 63-degree lower limit.
