wiring honeywell CMT 927 thermostat relay

[ngfec25]

I have a ferolli optima 701 combi boiler that is located in my loft and have just purchased a honeywell CMT 927 wireless programmable thermostat that will enable me to alter the settings from downstairs.

My question is regarding the wiring of the relay to the boiler, if anyone could advise I would be most grateful. I have attached photos of both connections
