Worcester boiler not responding to rf

I have a Worcester 30cdi boiler in a garage. It is hard wired to a RF receiver in the house which receives info from a thermostat. Boiler fully serviced. RF replaced and new. Danfoss RX1 is receiving info as lights on when temp adjusted up/down. Power from boiler site. However no green light on boiler and no CH. If bypass RF by linking positive to 4 then CH on constantly so messages are getting through. Reinstate new RX1 and then it doesn't work! Wits end. Help.
