Could the valve itself the brass 22mm be the problem? xcbd`g`b``8 "@$0"9A$r L.l"`r.474LI6 "El"`[Z1dQ A6[mdV"H1 ;*Y XjV^TE"*Sf8L: Valve microswitch | Screwfix Community Forum Aboard the Viking Lines cruise ship M/S Cinderella, Danfoss AC variable speed drives are delivering fuel savings so large that the cost of installing the drives will be fully recovered in less than eighteen months. The needed adapter for the actuator to be able to be mounted on the valve is 065Z0312. Increased reliability and operational safety due to built-in thermic and overload protection of the electromotor. Pipes are connected to the valve by two or more compression fittings. :S~j{;ZCt'hPvel,]KbG&-Y'`q@td14'\rg\:p6RR2Bcm2O+{F48SM' Is this the valve that needs replacing of is it the stat or both! Wouldn't that tee have been better placed in the 22mm section? I am going to look up Synchron and see if I can understand. 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. Read more Sometimes if the system has low inhibitor the limescale can lead to the valve becoming stiff when operated, holding the switch closed when power removed, causing the heating to run on. I have tried the manual override but that does not close the valve. I presume the Danfoss is the central heating on/off valve and the Honeywell controls the hot water. The synchronous motors do conk out a lot but they are easy to change. While the actuator is off, you can check whether that works by calling for heat in whichever circuit it controls and seeing whether the bit which connects to the valve shaft rotates as expected, and then returns to the closed position when the demand is removed. We are currently experiencing problems starting configurator FC 102. How come you have x2 cylinders? Can You? Danfoss Climate Solutions 08/2022 AI353237365414en-010102 1 Features The H-Series Motorised Valves, working in conjunction with time controls and thermostats, are used in domestic and commercial central heating, hot water and chilled water systems to control the flow of water in the system.
