Would be easier if you gave us the model number: the number you quote is RKC's code.
From the description of the problem I think you have triggered the run / stop mode selection: check page 5 of the manual (assuming what you have is a CB100 or similar).
BTW RKC controllers are lovely bits of kit IFF they are genuine: I use one to control my composites curing oven where a mistake can cost me thousands of dollars and several weeks work.
Unfortunately there are about a billion cheap Chinese knockoffs on the market and they are usually unreliable shit. If you bought it on Ebay and it isn't doing what you expect it to, throw it in the bin and start again.
Edit: I realised that IFF is probably opaque to many readers. It is an abbreviation for "if, and only if" used in formal logic.
