Active Setpoint; Actual Capacity - Daikin MicroTech II Installation And Maintenance Manual

Active Setpoint

Keypad Menu Path: This output network variable indicates the current value of the setpoint temperature used to control the
temperature of the Leaving Chilled Water or Leaving Hot Water. Based on the operating mode of the
Menu
chiller, this value is derived from the Cool Setpoint, Heat Setpoint, or Ice Setpoint. The default mode is
\Set
Cooling and is used unless changed by the Mode input. (A2)

Actual Capacity

Keypad Menu Path: This output network variable indicates the percent of capacity the chiller is currently producing. It may
be more or less than the nominal capacity of the chiller. For Centrifugal chiller models, this data point
No Keypad Equivalent
represents the combined percent RLA of the compressors. For positive displacement chillers (those
using screw and scroll compressors) this is a percentage of total compressors running. (A10)
