It appears you have not defined at Hot Deck Max Leaving temp
(HEAT-SET-T), which needs to be specified for the central Furnace
coil to be energized in the simulation. Also, for PIU (and I
believe all the other multizone systems), the central coil LATs will
track the Cool Control properties, which in your case, is an OA
Reset Schedule. I suggest setting up an hourly report for the air
handler coil leaving air temperatures, and observing what is
happening are to understand how the control set points are being
implemented.<br>
<br>
Hope this helps, <br>

<div>Dear all,</div>
<div> </div>
<div>My question relates to distributing space heating between the
central VAV RTU (natural gas furnace) and PIU terminal units
(electric resistanct heating). My elecriticy consumption for
space heating end use seems very high from November to April
which makes me suspect that the system is not set up accurately
- majority of space heating is wrongly being picked up by
electric resistance in terminal units as opposed to being picked
up by the natural gas furnace in the RTU. </div>
<div> </div>
<div>From the BEPS report, of the total annual energy consumption
of 372.7 MBTU, 148.7 MBTU is electricity space heating and 7.6
MBTU is natural gas space heating.</div>
<div> </div>
<div>I have attached eQUEST screenshots of my heating and cooling
cap/control settings for this system. Any input on how this
situation can be rectified will be highly appreciated. </div>
<div> </div>
<div>Thank you,</div>
<div>Ramana Koti.</div>
