Re: [EnergyPlus_Support] Re: Thermostat Deadband



<p>You need to define for us very specifically what you mean by  
&quot;deadband temperature difference&quot;.</p><p>Read the Input  
Output Reference descriptions regarding the HVACTemplate:Thermostat  
object and the resulting ZoneControl:Thermostatic object... and see  
how they relate to how you are defining &quot;Deadband temperature  
difference&quot;.  In EnergyPlus, the thermostat &quot;deadband&quot;  
is simply the difference between the cooling and heating set point  
temperatures.</p><p><br />Quoting eplusven  
&lt;eplusven@xxxxxxxx&gt;:<br /><br />&gt; Yes that is true. I have  
specified heating as well as cooling  <br />&gt; schedules. But I did  
not find any provision to sepcify the deadband  <br />&gt; temparature  
difference.<br />&gt;<br />&gt; The following are heat and cool  
schedules for the thermostat I am using.<br />&gt;<br />&gt;  
Schedule:Compact,<br />&gt;     HEATSCHEDULE,            !- Name<br  
/>&gt;     Any Number,              !- Schedule Type Limits Name<br  
/>&gt;     Through: 12/31,          !- Field 1<br />&gt;     For:  
Alldays,            !- Field 2<br />&gt;     Until: 05:29, 13,         
!- Field 4<br />&gt;     Until:19:30, 22,         !- Field 6<br

&gt; Thanks Don!<br />&gt;&gt; &gt;<br />&gt;&gt; &gt; Could anyone  
throw some light on my first question<br />&gt;&gt; &gt;<br />&gt;&gt;  
&gt; &quot;I am modeling an office Packaged VAV HVAC using  <br  
/>&gt;&gt; &quot;HVACTemplate:System:PackagedVAV&quot; and thermostat  
using  <br />&gt;&gt; &quot;HVACTemplate:Thermostat&quot;. My office  
has deadband thermostat.<br />&gt;&gt; &gt;<br />&gt;&gt; &gt; In  
summer the dead band is 1 F and in winter deadband is 3F for a  <br  
/>&gt;&gt; base temparature 71F. The documentation specifies  <br  
/>&gt;&gt; HVACTemplate:Thermostat uses dualsetpoint with deadband.  
But I was  <br />&gt;&gt; not able understand how. Could anyone help  
me how do I model this  <br />&gt;&gt; Thermostat with deadband  
offset. &quot;<br />&gt;&gt; &gt;<br />&gt;&gt; &gt;<br />&gt;&gt;  
&gt; Thanks<br />&gt;&gt; &gt; -Ven</p>
