MiGenie Wish 1 Wiring

[hem30]

Hi, I'm trying to replace my elderly fathers heating thermostat from an older dial one to a new digital one (MiGenie Wish 1)

He has a Vailiant ecotec pro28 combi boiler. When i opened the pcb unit i noticed the thermostat was wired up directly (see pics). I have removed the old thermostat and connected the new thermostat to the 24V RT connection where the previous one was. Is this correct? or do it need to be connected to the 230V RT connection? Also, there doesn't seem to be a connector for this?The heating does work on and off using the new system but it does see to take a long time to get to the temperature? Have i wired it correctly?

(Attached are pictures of the old thermostat wiring)

TIA

That MiGenie 1 is voltage free contacts, so it’s fine how it’s been wired up, although the front cover forms part of the combustion circuit, so should have been checked for safety afterwards. The connector for 230vac should be there, but suspect has been removed at point of installation. Did the old one take a while to heat up?
