I have been considering a RLT1720 for a while, but I have seen a posts from "MarkHudds" (Which has been closed for some reason) asking for info about controling it with a Sky remote. This kind of put me off as if I have to use 2 remotes, I can't really be bothered.. But I have been offered the chance to get a 1720 cheap, so decided to look into it. I dropped a mail to Relisys but didn't expect them to reply, but to my surprise they replied with this: "Thank you for your enquiry. The IR code for the RLT1720 is 0877." Can someone try this code and see if it works?
