nviShare
In some cases a sending node(master VAV controller) with a wall module
may be used to control the damper, ReHeat and Peripheral heat of one or
more other receiving nodes (satellite VAV controllers) that do not have a
wall module. To use this feature:
All nodes involved must be configured to have the same kind of ReHeat
via ReHeatType.
The satellite receiving nodes must have FlowControlType set to
ShareWallModule.
The satellite receiving nodes must have nviShare bound to nvoShare of a
node having a wall module.
Notes
nviShare can be used as a fall back strategy for a Wall Module space
temperature sensor failure. In this case, FlowControlType is set to normal.
When the space temperature sensor fails, the master VAV controller will
take over control of the satellite VAV (controller with failed space
temperature sensor).
nviShare.TempFlowCmd must be a valid numerical value before any Wall
Module sharing functions are enabled.

Notes:
Refer to nvoNodeStatus.manual_control
Mode 6 (Pressurize) and Mode 7 (Depressurize) are ignored if the
controller is disabled. Use network input nviEmergCmd to override a slave
controller in the disabled mode.
