Coversheets are usually required by the Clerk's office for filing purposes. I don't think a 4F is used for a temporary order -normally that would be the motion and order information form coversheet.
But regardless, a coversheet is not required for an order to be in effect. The part signed by the judge is all that is required.
If you have an order signed by a judge and file-stamped by the clerk of court in your matter, then it is more than likely a valid enforceable order, which each party would need to abide by.
