[Equest-users] HVAC System Lockout

[Nick Caton]

Cory, your query needs more description to include what you're trying to
model and what you've input, but if you've got simultaneous calls for
heating and cooling being handled, it sounds like you have either a
multi-zone system or multiple systems specified where you want only (1)
single-zone system.  

 

If I were trying to model the behavior of the HVAC in my apartment
accurately (a simple CV electric furnace with DX cooling controlled by a
single remote thermostat), I'd group all conditioned spaces and their
zones under a single system, taking care to assign the thermostat zone
where the thermostat actually resides - it's the zone highlighted red in
the graphic under the airside HVAC tab.

 

I'd suggest revisiting the quantity and type of system you've specified
first, and modify/reassign your systems/zones as necessary to see if
that's where the problem resides.  If you're still having troubles,
you'll need to provide a better description of what sort of system
you're trying to model (layman's terms are fine in this forum) and what
you've tried to specify on the model side.  Attaching your project's
.inp/.pd2 files may encourage others to help troubleshoot also ;).

 

Best of luck!

Is there a way I can create a schedule to lockout either the heating or
cooling system based on the time of year?  I am modeling a residential
system, so I don't want it to try and satisfy heating a cooling loads
simultaneously in different zones.  Thanks
