This kind of actuators, like AME 435 and AME 655/658/659, are able to work with AC or DC voltage but only for 24V in one or 230V in another version of the actuator, not both at the same time. As others have said, this looks like an S-Plan system with the hot boiler/pump feed on the left, and then splitting into 2 circuits at the tee - with one valve for hot water and the other for central heating. Three port mid position valves which allow water to be routed to the hot water circuit, or the heating circuit, or both. The actuator doesn't provide all that much torque so even if you can move the valve with the manual lever, the actuator may not be able to move it if it is stiff. Is the speed of the actuator fixed and permanent, or can I modify/change it? I'm assuming that the ?22mm pipe coming in from the left, the middle one of the three, is the feed from the boiler, which is then split two ways, down through the grey Honeywell to the DHW tank, which opens when the tank thermostat calls for heat, and horizontally through the white Danfoss to the CH system, which opens when the house thermostat calls for heat.

With CH on and HW on manual I can feel the hot water entering the tank but if I stop the CH the boiler stops even though HW demand still on. or if you are doing it yourself you can find suppliers local to you. Obviously my manual intervention cleared whatever gunk was preventing automatic actuation! endobj At the moment HW and CH are working as expected. There are lots of clones about that are cheaper but for a few more pounds I think its worth replacing Synchron with Synchron (the original that I replaced has been controlling the flow to the central heating for more than 12 years so its done a lot of work). Where do the three pipes involved go to/come from? Could the valve itself the brass 22mm be the problem? How does the safety function, or the so-called spring return function, work and what does SD and SU mean? Recently we had reason to replace our boiler.
