I'm needing to replace a Drayton Mid Position valve Actuator, code MA1. The failed one is 3-wire (red, green, black) but all the new ones I've found advertised are 5-wire (yet the cover data plates are identical!).

Question is - can I replace the 3-wire actuator with a 5-wire, and if so how should I wire it? Or are 3-wire versions available?

Thanks!

Are you sure the installer hasn’t just chopped the wires off

No, that's not the case, as can be seen in the photo...

It seems to be, as it's just switching between HW and CH with no mid-position. So, can I put a diverter actuator on it and not an MA1? Which one if so?

Can you not just put a new motor in that one

Unfortunately not - the post/s in the chassis holding the 2 springs have snapped off so the valve is stuck in the CH position
