The 30-year-old had been a key figure at Blackburn, where he made 135 appearances over three years, before the Red Dragons lured him to Wales just before the summer transfer window closed.
As he prepares for his first return to Ewood Park, Hyam said: “I have a lot of good memories of my old club and I have a lot of friends there too.
“But at the end of the day it’s business and we want to put in a good performance and win.
“I loved it [at Wrexham]. The club has been really good and the fans too. I feel like I’m really at home and enjoying my football.”
Rovers are 19th in the Championship, five points clear of the bottom three, having won just two – but lost just three – of their last 10 matches.
