<font size=3>I don't think the behavior of INTERMITTENT changed from
DOE2.1e to DOE2.2. The DOE2.1e Supplement has the same wording as
the DOE2.2 manual. <br><br>
I would add some hourly reports - supply cfm, OA ratio, heating energy
and cooling energy. Run for both CONTINUOUS and
INTERMITTENT. There may be some differences in the amount of
outdoor air that is being introduced. <br><br>

I am also investigating "intermittent" as it affects EnergyPro,
which claims to use "DOE-2.1E* v119".<br><br>
The issue involves using "INTERMITTENT" and how that affects
heating energy. Heating energy drops dramatically when
"INTERMITTENT" is invoked. It drops so far that it does
not seem realistic, although no errors or flags result that I can
find.<br><br>
I have found some references to "INTERMITTENT" causing negative
CFM:

Question - Do you (or anybody on the list) have any ideas why invoking
"INTERMITTENT" in a program that uses DOE-2.1E*V119 would show
such effects on heating energy (very, very, very low)?????<br><br>
<br>
Thanks for thinking about this!<br><br>

Do you have the DOE2.2 Reference manuals? DOE2.2Vol2-Dictionary.pdf
explains what the INTERMITTENT keyword means. <br><br>
See page 361 under INDOOR-FAN-MODE.<br><br>
The reference manuals are available for download at <br>

Download the latest edition of each manual and enjoy!<br><br>

<blockquote type=cite class=cite cite="">Hi all,<br><br>
I tried searching for an answer on archives but unable to find an
answer.<br><br>
I in Schematic Mode I set fan to "intermittent" meaning
HVAC fan is only on when heating/cooling is needed... <br><br>
1) if I set it a value of "1" fan is on alwayst on<br>
2) Set 0 Fan is "off"<br><br>
Since it is in intermittent mode, when i set to 0.... there is never any
cooling. what am I doing wrong? Because if i set fan schedule
in Detailed edit mod to 1 the fan is always on and I don't want
that.<br><br>
I want intermittment fan schedule but it's either 1 or 0 in the fan
schedule...<br><br>
<br>
Thanks!<br>
