I have a Honeywell HY-254E that looks exactly like the model in this guide. However, I have a problem with two of the screws. In my case the two middling screws that hold the backside of the main case and thatare above described as "3/4" Phillips #02 screws" look like Torx screws.
However, I don't have the right driver and I'm unsure which Torx size I need. Does anyone have an idea which Torx size this could be?
