How to remove thermostat and just have timer

[wifedoingheadin]

Hi I have a two year old Honeywell wireless thermostat and the screen has failed. I want to remove it and the BDR91 receiver. How do I remove so that the circuit works.
Then I want to replace the original wall timer (which has been permanently ON) for water / heating with Hive (simple change as same NL1234 back plate on a condenser gravity water / pump boiler.
Problem is the wiring of the 10-way for the wireless by the tank is confusing me.
1 is L, 2 is N, 4 and 5 go to A and B in the BDR91.
Do I just short 4&5 or must I connect the Live wire to one of them?
Thank you

POwer off.

Remove the head of the BDR, join the cables in A and B.

Put head back on and power up.

Job done.
