RE: [EnergyPlus_Support] Re: Thermostat Deadband

[YuanLu Li <yli006@xxxxxxxxxxx>]

Hi, Ven
 
I am interested to see your .IDF file, because there are now more than one ways to use the DeadBand.
 
In the older version, the deadband comes with the type 4 thermostat setpoints.  I believe it is still there in version 4.  However, some template models do not seems to need to declare this any more, because of the smarter managers..
 
I am interested, because I am a collector of error messages.  The best way to learn computer programming  is to make errors and then try to follow the error messages and debug the problem.
 
It is possible that your schedule  is enter in the wrong field of the calling object.
 
The schedules themselves are correct as the year:day schedule for thermostat.  I usually use 'temperature' for the Schedule Type Limits Name. ('Any Number' has no limit.)

Yes that is true. I have specified heating as well as cooling schedules. But I did not find any provision to sepcify the deadband temparature difference.

The following are heat and cool schedules for the thermostat I am using.

Schedule:Compact,
HEATSCHEDULE, !- Name
Any Number, !- Schedule Type Limits Name
Through: 12/31, !- Field 1
For: Alldays, !- Field 2
Until: 05:29, 13, !- Field 4
Until:19:30, 22, !- Field 6
Until:24:00, 13; !- Field 8

Schedule:Compact,
COOLSCHEDULE, !- Name
Any Number, !- Schedule Type Limits Name
Through: 12/31, !- Field 1
For: Alldays, !- Field 2
Until: 05:29, 32, !- Field 4
Until:19:30, 23, !- Field 6
Until:24:00, 32; !- Field 8
