Caldecott, 38, was promoted from assistant following the shock resignation of Tom Baker last week.
He said: “I want to solely concentrate on managing now and my responsibilities towards TFC.
“I’ve had my time playing for Trafford and I am proud to have represented us, and many other great non-league clubs in Stalybridge, Ashton and Hyde to name a few, so I’m officially done.”
Caldecott has been at Shawe View since 2014 and said he didn’t have to think twice about taking up the role.
“Tom resigned & I had a call from the Chairman with the offer to step up and be the manager.
“Before John (Eadie) could even finish his sentence I was repeating “yes, yes yes” in my head! So no, I didn’t think twice! I accepted the opportunity straight away and now I cannot wait to get started!”
Caldecott won’t be rushing in to new signings, and says he wants to wait until a realistic date is made available for a return to action.
Existing players have been sent home routines to follow.
He added: “Announcing players is best delivered when we return properly as a club. Sorry for no immediate news, I know people would like to know where we are, but I can assure everyone that come the start of the new season, whenever that may be, TFC will have a group willing to give their all as we have over the last 5 years.”
