Drayton Wiser Wiring

Páid

I bought a two channel Drayton Wiser heating Controls on Prime Day.

I just want to be sure of the wiring before I connect it. There are existing heating controls (very old) that I want to replace. The Hot Water on the heating controls won't be used, just the Central Heating. There is a 16a fuse at the fuse box that feeds other stuff (TV, Horizon box) as well as the heating controls so I need to fit a 3amp fuse for the heating controls.



There is a neutral and live going from the existing heating controls to a dual plug which the boiler and circulation pump are plugged into.


To connect the new heating controls I should do the following;

1. Connect a 3amp fuse inline
2. Connect the live to L
3. Connect the two neutral wires to N
4. Connect the live going to the boiler to 4

Is this correct?

Yes. Spot on. To fuse the Drayton, a simple spur box like this is perfect, and meets regs.

When you say an 'inline fuse', be sure to use a mains approved one like below, and not a common inline holder used in automotive and low voltage circuits.

That's great, thanks for the response.

I'm going to fit the unswitched fuse spur beside the heating controls.

Got this installed today and it worked first time. Thanks for all your help.
