I don't think pushing and pulling are technical banking terms (I could be wrong) but it seems to be the easiest way to remember the deposit flow.
If you want to use the Cap1360 to make a deposit into the PNC checking, setup the transfer from Cap1360 and send the money to PNC. This is a
push of funds into the new account.
If you were to setup the transfer from PNC and ask for the money from your Cap1360, that would be a
pull of funds into PNC. Since you're initiating it from the targeted account (PNC) it won't be considered a direct deposit since you asked for it (at least it's highly unlikely).
I like to think of direct deposits as a surprise to the deposit account, just suddenly it was directed deposited in there like your paycheck
