(REUTERS) - Dallas Federal Reserve Bank President Richard Fisher said on Thursday U.S. economic conditions were improving, and he cautioned against viewing the central bank's 2014 projection for raising interest rates as an iron-clad promise.

The intention, as I view it, of the committee is to make sure that we adjust to the real economy and as new data comes in, more anecdotal evidence on top of that is confirming what the data says, then we will adjust. The question is when, he told CNBC.

I happen to be a little more optimistic about economic movement here than some others on the Fed's policy-setting panel, Fisher said.
