Wiring manual thermostat to room heater

[Spursnwagos]

The thermostat instructions show you how to do it. [Earth omitted for clarity ] I've shown the A version, but the principle is the same if you have one of the other versions.

The heating load is the 'heater' and you can connect it via a plug and socket if you like. However as has been pointed out the thermostat is rated at 10A (resistive) so someone could in theory come along and plug in a 3kW heater (13A) which wouldn't be a good idea.

Perfect, this is a much better diagram than was included - just as needed. Thank you. The heater is being directly connected to the thermostat (plug removed), should be around 3.5A - 800W.
