Wireless Thermostat

I want to replace the CM907 room thermostat controlling a Worcester Bosch combo-boiler, with a Salus ST620WBC wireless thermostat that fits onto, and plugs directly into the boiler. Can anyone tell what to do with the two existing wires to the room stat? Do I need to fit (refit) the link in the boiler?

The relay unit normally fits hard wired to the boiler-the actual wireless 'stat is fitted where the existing room 'stat was installed. The install instructions should tell you how to connect the relay to the boiler itself.No free lunch, and no free laptop

When I swapped my CM907 to a netatmo wifi thermostat. I wired my relay to the two wires which had been supplying the CM907.
