Hi, I'm super-confused. My new ST9400C controller, V4043H zone valves and T6360B1028 room thermostat were all purchased as 24v items (eg see https://www.amazon.co.uk/gp/product/B003CSGRIQ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1). But now that I've got the wiring diagrams it seems they all need to be wired to a 240v main supply. Nothing in the instructions makes any mention of 24v. What's going on here?
Also, I currently drive the old (malfunctioning) zone valves that I'm replacing with an old ST7100 (230v) controller. Could I drive the new V4043H valves with the old ST7100 controller?
