Q: Is this a simple / direct replacement for the RDJ10RF unit,

A: Yes it is.
Q: What temperature should I set the control dial at on the boiler for the heating or does the wireless thermostat override the boiler temperature setting

A: The boiler manuacturer will recommend a most efficient position for the boiler thermostat in many cases this will be maxiumum. The room thermostat will not effect it.
Q: Is this thermostat compliant with boiler plus regulations?

A: To comply with Boiler Plus you will need either a separate Flue Gas Heat Recovery or Weather Compensation control when using the RDJ100-RF.
Q: Can the thermostat control be portable or does it have to be fixed.

A: It comes with a table stand, so you don't have to wall mount it.
Q: Is the wiring in diagram same as the previous one?

A: Yes it is.
Q: Could you tell me what bonded ex factory means on the descripition means please

A: It means to do not have to teach the thermostat and receiver to talk to each other on installation. Siemens have already done this for you in the factory.
