Unused Non-Parent Objects

I'm casting about, trying to figure out why:

  • zones are not meeting their setpoint
  • there is apparently no recognized value for the zone node's "System Node Setpoint Temperature" for output:variable (it displays as a large negative value), despite using a normal combination of SetpointManager:SingleZone:Reheat and ZoneControl:Thermostat for my single zone air loops

As I look for clues, I see in the .SVG file that all of the SetpointManager:SingleZone:Reheat objects are identified as "Unused Non-Parent Objects". I'm fairly sure that may have displayed in the past, but I never had good reason to dig into it before. A search of the IO Ref and Engineering Ref does not result in anything...

So, may I please have some ideas about:

  1. what may cause the zone node to have no associated setpoint value?
  2. whether an "unused non-parent object" is a problem?

p.s., In case you're interested and able to take a look, the IDF is here

Unused Non-Parent Objects

Dear forum, I'm casting about, trying to figure out why:

  • why: * zones are not meeting their setpoint
  • setpoint * there is apparently no recognized value for the zone node's "System Node Setpoint Temperature" for output:variable (it displays as a large negative value), despite using a normal combination of SetpointManager:SingleZone:Reheat and ZoneControl:Thermostat for my single zone air loops

As I look for clues, I see in the .SVG file that all of the SetpointManager:SingleZone:Reheat objects are identified as "Unused Non-Parent Objects". I'm fairly sure that may have displayed in the past, but I never had good reason to dig into it before. A search of the IO Ref and Engineering Ref does not result in anything...anything....

So, may I please have some ideas about:

  1. about: 1) what may cause the zone node to have no associated setpoint value?
  2. value? 2) whether an "unused non-parent object" is a problem?

    3.

Thanks in advance for your insights.
