The HC60NG has been cycling my boiler for some time now and slowly driving me crazy, so why I didn't think of this solution before blueridge guitar now is a mistery ! I've added a 'time delay' relay into the boiler control circuit. The relay coil is energised by the HC60NG
when calling for heating, the relay contacts supply blueridge guitar the boiler with 240v. The relay allows a variable time delay to be set between the coil energising and the contacts closing. blueridge guitar I've used 10min as a delay time. If the HC60NG is simply cycling (as it tends to do, a lot) then the relay will receive the 240v feed, but the boiler will only start if the 240v feed exists for more than 10mins (in my case). As a result the relay filters out the cycling request and only starts the boiler when the controls ovl tekniikka blueridge guitar are making a more serious request for heat. Boiler cycling has now completely stopped, the only very minor downside is that I have to wait 10mins before ovl tekniikka the boiler

ovl tekniikka will start after a genuine request but this has actually not been noticed. Hope this helps somebody out there... That's very interesting. I'm not a big sufferer, but may still give your solution a try - it certainly sounds
ideal. What's the name of the relay, ovl tekniikka and where can I buy one? Thanks for sharing your innovation. Quite often boiler cycling can be caused by the rad water temp not set high enough (this is normally adjusted at the boiler), or the setback temp is too close to the normal temp. While you have solved the problem you may not have fixed the condition that causes ovl tekniikka it. But good idea anyway. I've done extensive testing with my Hometronic system, the HC60NG causes the cycling problem and the boiler is the victim. No matter

what you do with set-back, temperatures, blueridge guitar ovl tekniikka etc the system blueridge guitar eventually returns to cycling as rooms reach the set-point. The only sure way to avoid the problem is to set-back to a temperature way below a point that you could ever reach in each zone, this (in my mind) defeats the potential advantages of using Hometronic in the first place.

this method seems to be one way of saving the boiler from this constant bullying Fair enough, I wonder if the house heat system has similar problems. And I guess Honeywell aren't that bothered in updating the firmware. Or if they do it will probably cost. Did you have a look at the DIYnot forums. ovl tekniikka http://www.diynot.com/forums/viewtopic.php?t=157962 don't know if this is of any help to you. In the defense of Honeywell perhaps it depends on the design philosophy ovl tekniikka behind the firmware. If the aim was to offer accurate temperature control in each zone, and quick reaction to heating demand, then maintaining the circulating water at close to required temperature would make sense. ovl tekniikka A regular boiler cycle would ensure hot water was always available even if actual demand was minimal. The system could then react quickly ovl tekniikka to a valve request. I'm of the opinion that the running cost and system wear & tear are increased as a result...given the option I'd prefer to have the boiler stay off overnight ovl tekniikka - thus the relay The cycling is part of the HC60NG firmware, the genuine reason for it's inclusion ovl tekniikka would be great to understand but as with a lot of the Hometronic blueridge guitar options I can't find any details. I'm happy with the Hometronic as a package, and more so now the HC60NG has been put on a leash ! 9 months later and I've finally fitted the time delay relay! It's working beautifully, intercepting all the unwanted cycling requests. I have set the time delay at 3mins 15secs for now. If anyone would like to know the wiring of the Broyce Control M1EDK I'd be happy to pm. Thanks again to drawdog for the idea and advice.
