Hive wiring to ideal 30 combi boiler

[Thomas Lambert]

Hi all I’ve just purchased a hive single channel unit, I’m going to install myself, just looking for some advice, I currently have a wireless thermostat (center) would it be just a straight swap to hive? I have taken a photo of my current setup next to the boiler. With hive it’s just live and neutral then the other 2 cables to 1 and 3 on the hive, does it matter which way round 1 & 3 go? Any help would be appreciated! Thank you

No but normally supply in to com and supply out to normally open, but with my Nest with a C Plan no option but to connect com to boiler so no problem either way.
