I have a 240v AC main (switched) and wish to control a 24v DC logic with it.
Background: I bought a cheap WiFi enabled (Broadlink chip) thermostat to control my central heating. It's a surprisingly decent unit. However, up on receiving it I realised the output is switched mains, whereas the logic board on the boiler (Ferroli) is 24v DC.
What is the easiest/cheapest way to achieve this?
[Note- I realise this is the converse of the typical switching scenario wants and clearly the "cleanest" solution would be return the controller and get a more appropriate one!]
