<div dir="ltr">This is crankcase heat which defaults to 50 w. Thanks for all the responses!! I still don't understand why there is more crankcase use in the colder months, but I am all set for now.<br><br>Thanks!<br>

I believe this is crank case heating (SYSTEM:CRANKCASE-HEAT) which defaults to 50 Watts (0.050 kW) for PVVT with an on temperature (CRANKCASE-MAX-T) of 50. If you set CRANKCASE-HEAT to zero, I think this energy goes away.<br>

Date: Wednesday, July 23, 2008, 2:13 PM<br><br><div><div dir="ltr">Hi All,<br><br>I'm working on a project where I have a system type of "PVVT" specified. When I have air-cooled DX units specified, my "Pump & Aux" energy goes WAY up (about 4500
kwh are attributed to pumps and 19000 kwh attributed to something having to do with the DX units). The SS-P cooling summary report shows some sort of energy use for each unit every month, even when there is no cooling load. Curious thing, is that the highest loads are in the winter. I always result in 37.6kwh used in jan, 33.6 in feb, etc. I also ran a test module straight from the wizard with a PVV system. The system size is much larger, and it still uses... 37.6 kwh in jan, 33.6 in feb (the other months there is a cooling load). Any idea where this comes from or how to make it go away? The DX units will be OFF in the winter. It seems that the program is simulating some sort of heating for the DX unit.<br>
<br>Any thoughts?<br><br>Thanks,<br><br>--<br>Karen<br>
