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

Wouldn't it be nice if some of this stuff was discussed more in the
Manuals ??<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>

Thank you, Demba.<br>
<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>
