X X The Cooling Occupied Setpoint is used if no wall module setpoint pot is
configured as the standard Occupied Cooling Setpoint. Actual Cooling
Setpoint can be affected by various control parameters (such as DlcShed,
SrcRmtTempSpt, etc.). Actual room temperature Setpoint is reflected in
RmTempActSpt. Overridden by nviSetPt. Used to compute ZEB.

X X When the controller is in the Standby mode (typically via an occupancy
sensor), the base Cooling Setpoint is determined by the Cooling Standby
Setpoint value. Also, when a wall module setpoint pot is configured, this
value serves as the upper limit on the user adjustable remote setpoint pot
(wall module).

X X When the controller is in the Occupied mode, if the space temperature
drops below the Heating Occupied Setpoint, the unit switches to the
Heating mode. This Setpoint is used only when there is no wall module
setpoint pot configured. Overridden by nviSetPt. Used to compute ZEB.

nviRequest
(SNVT_obj_request)
object_id 0 to 65535 1 Request provides the mechanism to request a particular status report (via
Status) for a particular object within this node. Object_id selects the object
being referenced by nviRequest. The only valid value of object_id is 1 for
the RTU object and all others are invalid.

RQ_NORMAL When object_request is RQ_NORMAL or RQ_UPDATE_STATUS then the
status (via Status) will be reported for the object addressed by object_id.
When object_request is RQ_REPORT_MASK then the status bits will be
reported that are supported in nvoStatus by the object addressed by
object_id. Bits that are supported by the object are set to one. All other
object_request items are not supported at this time and will return an
invalid_request (Status) in the object status.
