LONWORKS
The LONMARK chiller prole uses two types of information to indicate chiller status. The rst type is general. The variable name is
nvoOnOff (see Chiller ON OFF on page 32) and indicates whether the chiller is on or off the network.
The second type is Chiller Status, which includes the Run Mode. The Run Mode is dened as OFF, Start, Run, Pre-shutdown and
Service. This output network variable indicates the main running mode and states of the chiller. The Run Mode provides the primary
running states of a chiller and the state provides an indicator of other conditions present (see Structure section below for details.)
