D. AH-1:4. Boiler operates to maintain a maximum of 180°F supply water temperature when outsideair temperature is 30°F, reset down to 80°F when outside air temperature is 70°F(adjustable).1. At beginning of occupied mode, outside air damper is opened. When damper is provedopen by an end switch, supply fan is started.2. Discharge air temperature is maintained at 73°F by modulating 2-way hot water valve onheating coil and 3-way chilled water valve on cooling coil in sequence.3. At end of occupied mode, supply fan is shut down and outside air damper is closed.4. If discharge air temperature drops below freezestat setpoint, fan stops and outside airdamper closes.E. Fan Coil Units (FC-101 - FC-219)1. Fan speed is manually set by occupant at room selector switch, or at individual units forfloor mounted fan coil units (OFF-HIGH-MED-LOW switching). Supply fans runcontinuously.2. 2-way hot water valve on heating coil and 3-way chilled water valve cycle open and closedunder the control of the room thermostat (OFF-AUTO-HEAT-COOL switching).3. For FC-201, 202, and 203 in Conference Room, control all three fan coils in parallel fromthe same room thermostat.F. Exhaust Fans (EF-1 and EF-2):1. Fans operate during occupied mode and remain off during unoccupied mode.3 .10 DIAGRAMSA. Install laminated schematic control diagram in each equipment room adjacent to the temperaturecontrol panel.
