The move raised a few eyebrows with the 33-year-old ending last season as Burnley's No.1.
His departure saw Bailey Peacock-Farrell drafted in from Leeds to bolster the goalkeeping ranks with Nick Pope playing every minute in the Premier League so far this campaign.
“I treat all these players like they're my own family members, I try and be as good with my guidance as I would be with my own children," Dyche told the Lancashire Evening Telegraph.
“I think it's important, they become important to you over time, Tom is certainly one of those. I don't do favourites, apart from Tripps (Kieran Trippier), everybody knows that!
“He was my first signing, an important signing, but he's a top fella on and off the pitch, I like him as a person and professional.
“There will always be a business decision here though, every pound is a prisoner, that's just the way it is.
“There is a method to the planning of it, but there often comes a time when a deal gets done here.
“With Tom, it worked on every level, and on the one that's hard to find, an emotional level, because I can shake Tom by the hand, look him in the face, he's happy, I'm happy, and there's no thinking on who's won, everyone has won."
