Not entirely on topic but what is a typical fan coil motor efficiency? I
have been using 25%. <br>

<p class=MsoNormal>Thank you, Jeremy. By "plug and chug", that seemed
to be the Parameter that changed in running a test building through Standard,
High, and Premium Efficiency.<br>
<br>
Wouldn't it be nice if some of this stuff was discussed more in the Manuals ??<br>

<br>
I account for motor eff by changing the total eff, where total eff = motor eff
* mech eff. I believe the keyword for total eff in the inp file is
SUPPLY-EFF for supply fans.<br>

But this is for a PUMP. Not a FAN.<br>

John, <br>
<br>
In the INP, it is the “MOTOR-CLASS” input. You see in the INP something like:<br>
<br>
FLOW =
300<br>
NUMBER = 1<br>
HEAD =
80<br>
MECH-EFF = 0.776<br>
<b>MOTOR-CLASS = HI-EFF<br>
</b>
CAP-CTRL = ONE-SPEED-PUMP<br>
<br>

I should know this one, but draw a blank.<br>
<br>
The Wizard asks if you want Standard, Hi Efficiency, or Premium Efficiency
motors for your fan system.<br>
<br>
How do those show up in the .INP file? That will give me a clue as to what
Parameters to modify for changing to PE motors.<br>
<br>
Thanks.<br>
