Re: [EnergyPlus_Support] Re: Thermostat Deadband
<p>You need to define for us very specifically what you mean by
"deadband temperature difference".</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 "Deadband temperature
difference". In EnergyPlus, the thermostat "deadband"
is simply the difference between the cooling and heating set point
temperatures.</p><p><br />Quoting eplusven
<eplusven@xxxxxxxx>:<br /><br />> Yes that is true. I have
specified heating as well as cooling <br />> schedules. But I did
not find any provision to sepcify the deadband <br />> temparature
