Before taking a look at this, last night the motorised valve has started clicking every few seconds, but only when HW and CH are both selected. 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.

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 I can reset it manually by moving the little metal tab back and forth a couple of times to unstick it but its happening more and more often. xc`````ab`c`A The motorised valve appears to be constantly open. Based on thorough analysis and a long-term strategic approach, the 30 year old system is gradually transformed into a modern and smart energy system. It supplies 18-20% of the annual heat consumption in the city of Silkeborg, Denmark, which has an ambitious target of CO2 neutrality in heat production by the year 2030. All of which adds up to enhanced comfort for the end-user. I have tried the manual override but that does not close the valve. The 2-port motorised valve on the central heating isn't turning off once the room thermostat is satisfied and so the boiler continues to fire until I turn the boiler off at the mains.

I am going to look up Synchron and see if I can understand. In Europe, 30 percent of all energy consumption goes to heat or cool buildings. Whilst it is in repair you can operate your system with the valve spindle manually turned so that its approx at 2 o'clock wrt the valve. If the motor is forced to draw too much current (in this case probably by excessive mechanical resistance in the valve mechanism) then the windings will overheat and are likely to eventually develop an open circuit failure. Manage Settings Just one point: you mentioned that those motors are brushless and therefore you dont understand why they burn out. To close the valve, power is removed. There are several reasons why a motorised valve might fail but usually, the fault will be with the actuator assembly. Your online portal for Danfoss sales and technical support for wholesalers and installers within Refrigeration and Air Conditioning industries and applications. AMV means that the actuator is either 2-point or 3-point controlled, AME means that the actuator has modulating control. Electrician Talk | ElectriciansForums.net. << /Filter /FlateDecode /Length 904 >> AUX switches are additional switches in the actuator that send signals to the recipient (can be other actuator, boiler, pump or controller) when the certain point of the actuator position is passed, this usually means when actuator end positions are reached (totally open or closed). Oct 20, 2011. and the wiring is slightly different , on the danfoss it has 4 wires ,,grey, blue,orange and (brown and white combined) on the honeywell it has 5 wires ,, grey,blue,orange .

Thank you for taking the trouble to explain. step 3 - turn down room stat - boiler shuts down. The consent submitted will only be used for data processing originating from this website. There seems to be a problem completing the request at present. #1. i have removed my broken danfoss 3 port valve as the ch was coming on with the hot water only, my problem is i have replaced this with a honywell 3 port . in the AME 435 and AME 655/658/659 actuators, you can change the characteristic of the actuator with DIP switch settings. To be honest, the price difference is not that much. In future there will also be a AME 685 actuator which can be used.See the technical details for AMB 162/182 actuators: http://products.danfoss.com/productrange/list/heatingsolutions/control-valves/actuators-for-rotary-valves/amb-162-182-/#/, Most actuators do not work on AC and DC voltage because they have synchronous motors technology. Start point - actuator is pointing almost fully to HW, but not quite - say 85deg out of 90. step 1 - turn up room stat - no response on anything. I had an engineer out today to quote me for a boiler install. 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). The central heating comes on and then stays on as the valve sticks open. Ive got a sticking Danfoss control valve. The worlds largest solar heating plant in Silkeborg, Denmark harnesses energy to heat the homes and workplaces of 40,000 citizens. Make safe the blue eg choc block. Its the microswitch thats sticking. Read more Your email address will not be published. You could probably get away with replacing the synchro motor, if youd prefer to try that first. It's a Danfoss valve - is it straightforward to replace the actuator? Danfoss 2 Port Valve Actuator ; . For a better experience, please enable JavaScript in your browser before proceeding. I was excited to try out the manual override on my HW diverter to see if it got the boiler firing but no joy still. The 2 or 3 I've replaced have always worked fine with a new motor fitted but they were Honeywell not Danfoss. It's a Danfoss valve - is it straightforward to replace the actuator? There are no visible signs of burn out. This could lead to catastrophic consequences for the application/industry and most importantly for the safety of everyone in the vicinity of the valve as it can have more than 130C of pressurised water in the system.The safety function enables you to close or open the valve automatically (via the spring inside the actuator) each and every time the power goes out. So somehow the motors cant move the valve yet the manual override seems to work fine. An example of data being processed may be a unique identifier stored in a cookie. Certainly whipping off the actuator for a look, and seeing if the valve spindle moves is a good first start. My Boiler Wont Switch Off Danfoss Motorized Valve When the central heating system is switched on the danfoss motorised heating valve is opening the central heating water valve to allow the radiators to heat up, however when the central heating system switches off the danfoss motorised valve will shut off the water valve and stop circulation to the radiators as it should do but fails to send the signal to the boiler to shut down into standby mode, subsequently, the boiler and central heating water pump continue to run while not heating the radiators or hot water.Fitting a new danfoss motorised valve solved the problem.https://www.amazon.co.uk/Danfoss-HPA2-Actuator-4-Wire/dp/B003QZKN26/ref=pd_sbs_60_1?_encoding=UTF8\u0026pd_rd_i=B003QZKN26\u0026pd_rd_r=42ac493d-0c1e-11e9-9334-2994f224cbbe\u0026pd_rd_w=h0x4s\u0026pd_rd_wg=1lkQw\u0026pf_rd_p=18edf98b-139a-41ee-bb40-d725dd59d1d3\u0026pf_rd_r=3QB3CCSPH0R6KCBK5DMQ\u0026psc=1\u0026refRID=3QB3CCSPH0R6KCBK5DMQ Danfoss Tech Insider keeps you updated on a monthly basis with the latest news on cooling and industrial products portfolios from Danfoss Climate Solutions.

Thanks Shaun I will have a go at it on Tuesday, Thanks for all of your help, I hope you have a great Christmas. This solution is, however, not recommended as you will not be able to know how much faster the actuator is actually moving.We recommend that you choose Danfoss AME actuators with BLDC motors technology as they have speed selection possibility on DIP switch. Reply Roger Bisby The manual override works OK.  k"endstream In this video, Roger shows you how a motorized valve works and what you need to do to diagnose and repair a motorised valve and avoid buying a costly replacement. If a motorised valve is making a buzzing noise and not opening the central heating pipe is that likely to be just the actuator that's gone? In the fault state, the silver lever below the valve can be . To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. NEW DANFOSS RANDALL 2 PORT 22mm MOTORISED VALVE 087N664200. Now new BLDC motors are coming and this technology can work on AC or DC actuators due to the so-called serial connection between stator and rotor of the electric motor. If you have DC voltage in the system and have an AC actuator, we recommend to look for a suitable replacement or install an inverter in your system.See the technical details for AME 435 actuators: http://products.danfoss.com/productrange/list/heatingsolutions/control-valves/actuators-for-seated-valves/actuators-for-heating-cooling-/actuators-without-safety-function/amve-435/#/. If it's a new system and it has done this since installed, don't discount the possibility that it has been wired incorrectly.
