PUMP NUMBER 1 — When the Aquazone System Control Panel is configured for variable speed pumping, this point displays the speed of Pump 1, as determined by a PID loop set to control supply water pressure. When the Aquazone system control panel is configured for constant flow this point will display 0% when the pump is OFF and 100% when the pump is on.

NUMBER OF STAGES — Table 13 is used with the follow- ing four points to determine the number of stages that should be active for the percent output displayed and the hardware installed with the Aquazone system control panel. When the outputs are configured for staging the second output will ramp up when the first output has reached 100%. While the second output is controlling the temperature the first will be held at 100%. When the second output ramps down to zero percent the first output will resume temperature control.

COOLING TOWER 1 SPEED/LEVEL — When the Aqua- zone system control panel is configured for variable speed cooling tower control, this point displays the speed of tower fan 1. When the Aquazone system control panel is equipped for staged output, this point displays the percent of stages commanded. The actual number of stages active will be determined by the staging cards ordered with the Aquazone system control panel. See Table 13. The value displayed is determined by a PID (proportional/integral/derivative) loop set to control the

COOLING TOWER 2 SPEED/LEVEL — When the Aqua- zone system control panel is configured for variable speed cooling tower control, this point displays the speed of tower fan
2.When the Aquazone system control panel is equipped for staged output, this point displays the percent of stages com- manded. The actual number of stages active will be determined by the staging cards ordered with the Aquazone system control panel. See Table 13. The value displayed is determined by a PID loop set to control the supply water temperature at the Occupied high set point.

HEAT SOURCE 1 SPEED/LEVEL — When the Aquazone system control panel is configured for modulating heat source, this point displays the percent open or percent heat capacity re- quested. When the Aquazone system control panel is equipped for staged output, this point displays the percent of stages com- manded. The actual number of stages active will be determined by the staging cards ordered with the Aquazone system control panel. See Table 13. The value displayed is determined by a PID loop set to control the supply water temperature at the Oc- cupied Low set point.
