ED 15062-7 • MICROTECH II CHILLER CONTROLLER

Chiller Status

This output network variable indicates the main running mode and states of the Chiller. The mode provides the primary running

states of a chiller and the state provides an indicator of other conditions present. (I18)

LONWORKS

The LONMARK chiller profile uses two types of information to indicate chiller status. The first 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 defined 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.)
