Hive install

[whale28]

Hi there - looking for some help on hive wiring - I have an existing programmer that I can’t make any sense of the wiring on:

I am trying to translate this to a single channel hive receiver. There is a wired thermostat in the hall that I planned to just remove and cap off the wires! Any help greatly appreciated.
