Help with wiring in a new Hive thermostat

[Benobi]

Hi, I've attempted to wire in a Hive thermostat. I have a megaflow style hot water tank, boiler and wall thermostat. I wired in the Hive receiver as shown in the attached pics. The black back plate is the original wiring which I then replaced like for like with the white Hive receiver back plate. The hot water comes on and off as it should via the Hive app, the central heating won't work at all. Any help much appreciated. Thank you.

You did purchase a dual channel Hive? What did you do with the wall thermostat and or wiring?

Hi - yes, a dual channel Hive. I disconnected the old thermostat wiring from the Honeywell box - pic attached. Cheers

You can not just disconnect the thermostat as you will leave the heating open circuit. In the wiring centre loop the 2 connections together where the thermostat wires were terminated.

Thanks for your reply - I'm not sure what 2 connections you mean though...?! Cheers

You said you disconnected the old thermostat wiring from the honeywell wiring centre, the terminals you disconnected the wires from will need to be connected together.
