color:#1F497D'>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. <o:p></o:p></span></p>

color:#1F497D'>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.<o:p></o:p></span></p>

color:#1F497D'>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 ;).<o:p></o:p></span></p>

<p class=MsoNormal>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<br clear=all>
