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. 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 best to replace the whole thing (which I can't do.)

Modulating, or AME actuators, are appropriate for precise regulation of the flow as they also have feedback signal and can position themselves very precisely in accordance to the signal from the controller. Add to List. Furthermore, AME (sometimes also called the electronic version of actuators) actuators provide more features on DIP switches and provide much more flexibility and control variations for the customer.

This is an intermittant fault. The vertical ?22mm pipe on the left is a return to the boiler, leaving the ?15mm pipe running behind the Danfoss unaccounted for. In the first case I was able to bend the microswitch actuating lever to make sure the switch was getting pressed, in the second case the brass gears werent good so I replaced the complete power head (again excluding the valve so no need to drain the system). << /ArtBox [ 0 0 595.276 841.89 ] /BleedBox [ 0 0 595.276 841.89 ] /Contents [ 1429 0 R 1430 0 R 1431 0 R 1432 0 R 1433 0 R 1434 0 R 1435 0 R 1436 0 R ] /CropBox [ 0 0 595.276 841.89 ] /Group 1437 0 R /MediaBox [ 0 0 595.276 841.89 ] /Parent 74 0 R /PieceInfo << /InDesign << /DocumentID /LastModified /NumberOfPageItemsInPage 11 /NumberofPages 1 /OriginalDocumentID /PageItemUIDToLocationDataMap << /0 [ 277 8 3 -240.945 -342.992 -124.724 -325.597 1 0 0 1 -182.835 -302.517 ] /1 [ 1901 0 2 56.6929 -219.685 172.913 -202.29 1 0 0 1 114.803 -179.21 ] /10 [ 9809 10 3 -116.22 375.591 212.598 389.764 1 0 0 1 -94.9606 387.496 ] /2 [ 1928 1 2 184.252 -12.0472 369.921 193.701 1 0 0 1 277.087 -29.0149 ] /3 [ 1957 4 0 184.252 -219.685 369.921 -50.0733 1 0 0 1 396.892 -230.498 ] /4 [ 1963 2 0 382.677 -219.685 566.929 -23.3858 1 0 0 1 371.053 -264.175 ] /5 [ 1968 6 2 381.969 -12.0472 566.22 216.567 1 0 0 1 382.469 166.844 ] /6 [ 8051 7 2 56.6929 -301.575 439.37 -252.283 1 0 0 1 114.803 -261.1 ] /7 [ 8362 9 3 237.543 374.882 269.291 389.764 1 0 0 1 239.199 390.472 ] /8 [ 8599 3 4 394.724 -213.307 559.134 -15.6588 0.464752 0 0 0.464752 394.724 -213.307 ] /9 [ 8607 5 4 194.882 -219.685 364.494 -50.0733 0.398819 0 0 0.398819 194.882 -219.685 ] >> /PageTransformationMatrixList << /0 [ 1 0 0 1 0 -420.945 ] >> /PageUIDList << /0 159 >> /PageWidthList << /0 595.276 >> >> >> /Resources << /ExtGState << /GS0 1460 0 R /GS1 1461 0 R >> /Font << /T1_0 1462 0 R /T1_1 1463 0 R /T1_2 1438 0 R >> /ProcSet [ /PDF /Text /ImageC ] /XObject << /Fm0 1439 0 R /Fm1 1440 0 R /Im0 1441 0 R /Im1 1442 0 R >> >> /Rotate 0 /StructParents 0 /TrimBox [ 0 0 595.276 841.89 ] /Type /Page >> If is *is* stiff, you may be able to free it by rotating it backwards and forwards a few times with a pair of pliers. What can be done, if it doesn't work?

I can just replace the actuator, no plumbing required, just need to wire up the new one. This switch is normally used to activate the boiler. Increased reliability and operational safety due to built-in thermic and overload protection of the electromotor. step 2 - start moving manual lever on actuator - boiler fires up, actuator continues moving on it's own to CH position. Please let us know if you like our Plumbing Basics and Tricks of the Trade videos. When I turned on the water for heating the Lever stay in position not moving( motor works ) but my central heating works as well even though it is turned off All the AME actuators have the possibility to choose either voltage input signal from the controller (U) or current signal from the controller (I) on a DIP switch. There are no visible signs of burn out.
