Type659 assess the thermal losses from the heater if there is flow
through the heater is not on (ie when the liquid is coming in hotter
than the setpoint). Type6 sets those losses to zero. Yes, a negative
energy delivered output from Type659 indicates that energy was
removed from the liquid stream. You'll notice that the energy
"delivered" and the loss term balance each other under that case.<br>

<div><br>
</div>
<div>In my system I have aux.heater and I use Type 6, but also I
tried with the Type 659.</div>
<div>My question is why with the same parameters for the
aux.heaters I get different results? ( bigger energy delivered
with Type 659) ?</div>
<div><br>
</div>
<div>When in the result is "negative" delivered energy, does it
mean that at that moment the temp. at the inlet of the heater
was bigger than the set?<br>
