Replacing a danfloss 4033 with a hive

[Stuneedshelp]

Hi

Need some expert direction .

So have got a new hive system and now need to replace the old danfloss 4033 . its a CH hw with a cylinder hotwater.

Has a mid value so that either can be on .

So mapped most part out but term 3 doesn't have anything in. Which according to danfloss is the on for heating. However in there diagram it does show this for one set up as empty.

Main question is if I replace like for like heating wouldn't come on.

Any help would be goid
