You need to connect the pressure as well. It is surprising that
you always get the warning. I would understand if you get that
warning for some timesteps (maybe even enough timesteps to go over
the allowable number of warnings in a simulation. However, if you
get that warning at every single timestep, there might be something
else wrong.<br>

<div>Dear all,<br>
</div>
<div><br>
</div>
<div>I´m using type 112 as a fan for an air-Source heat pump
(type401). <br>
</div>
<div><br>
</div>
<div>Between Type 15(weather) and type 112 i made the following
connections:<br>
</div>
<div><br>
</div>
<div>Dry bulb temperature => Inlet temperature<br>
</div>
<div>Humity ratio => Inlet air humidity ratio<br>
</div>
<div><br>
</div>
<div>But unfortunetaly I do always receive the following warning
which results in an Error:<br>
</div>
<div><br>
</div>
<div><em>"The referenced UNIT has called the PSYCHROMETRICS
routine witha humidity ratio above the saturation humidity
ratio for the given dry bulb temperature. <br>
</em></div>
<div><em>The air was assumed saturated at the given dry bulb
temperature and the humidity ratio set for this condition</em>"<br>
</div>
<div><br>
</div>
<div>Does anyone has a suggestion to solve this problem ?? I
appreciate any idea :)<br>
</div>
<div><br>
</div>
<div>Best,<br>
Michael <br>
