[esp-r] PMV?

[luochenglong]

Hello all,
When i simulate the thermal comfort level for a
building zone using ESP-r,there is a set for
predict mean vote(PMV) i don't know how i should
do.It asks"Which casual gain represents
occupancy?",and there are five options:Always
occupied,Lights,time,Occupt and Equipt.My trouble
is that i don't know the representations of the
five different opitons.It really confuses me a
lot,could some one expound it for me?
 Thank you for your attention!
