nviWindow
(SNVT_switch)
value 0 to 100 0 Window allows the window sensor from another node to be used as the
window sensor and is typically bound to nvoWindow of another node.
Window must show that the window is closed for 300 seconds before
Window is used as window closed. This makes it possible for several
window sensors to be ORed together by binding them all to nviWindow. If
any one bound window sensor shows window open, then Window shows
window open for up to 300 seconds after the last sensor shows window
closed. If the state is SW_OFF or SW_NUL, then the result is Window
Closed. If the state is SW_ON and the value is 0, then the result is Window
Closed. If the node receives this combination of state and value, then state
is set to SW_OFF. If the state is SW_ON and the value is not zero, then the
result is Window Open. NOTE: nviWindow is called nviEnergyHoldOff in

SW_NUL M X X Window allows the hard wired window sensor to be used by other nodes on
the network. The valid states are as follows: If the state is SW_OFF and the
value is 0 then the result is Window Closed. If the state is SW_ON and the
value is 100 percent, the result is Window Open. If the state is SW_NUL
and the value is 0, the result is Window Sensor Not Configured. NOTE:
nvoWindow is called nviEnergyHoldOff in the LonMark compliance profile.
nviEcon
(SNVT_switch)
value 0 to 100 0 nviEcon allows one controller to determine the suitability of outdoor air for
free cooling and share this with many other nodes. When Econ.state is not
SW_NUL, then the local sensor selected by Config.EconEnable is ignored
and Econ is used instead. The inputs states have the following meanings: If
the state is SW_OFF or other and the value is don’t care, then the outdoor
air is not suitable for free cooling. If the state is SW_ON and the value is 0,
then the outdoor air is not suitable for free cooling. If the node receives this
combination of state and value, then state is set to SW_OFF. If the state is
SW_ON and the value is not zero, then outdoor is suitable for free cooling.
If the state is SW_NUL, then the network variable is not bound, the
communications path from the sending node has failed, or the sending
node has failed. Outdoor air is not suitable for free cooling.
