VARIABLE LEAVING WATER TEMPERATURE CONT-
ROLS
Variable Leaving Water Temperature Controls are applicable
in water chilling mode and heating mode. The controls will
automatically reset cooling or heating liquid temperature
setpoints to match the required cooling or heating load as
ambient temperature changes. Four liquid temperature setpoints
in cooling, and ve setpoints in heating, are programmable to
formulate the variable target liquid temperature. The microboard
will interpolate to calculate the setpoints in between.
