In December 2012 I had my boiler replaced and DHW and UFH are from a Vallant Eco Tech Plus 630. Installed and everything fine until today
I have an 11 year old Megaflow. Never had to do anything to it or had any trouble with it. There are two Honeywell valves, in line, on the pipe leading into the base of the Megaflow.
My plumber, who I have been using for the past few years, queried why there were two valves fitted. However reading this post //www.diynot.com/forums/viewtopic.php?t=180039&start=15
this appears correct.
The valve furthest from the megaflow is a Honeywell V4043H1056. The other is too near for me to read but it is a Honeywell.
I must confess the electrics for my DHW and UFH baffle me. I have separate UFH electrics but the fitted DHW clock has CH settings and if I don't run the two together I don't get any DHW. I guess that is a electrical problem but it doesn't cause this problem.
Having read the above posting and searched on here I checked the reset button, didn't make any difference. However when I turned the Megaflow thermostat down to minimum the Honeywell V4043H1056 value "moved" as I heard that sliding sound. Turned the thermostat up and it moved again. Meanwhile the other value started clicking. The pipe then became hot under the valves and we have hot water.
I have now noticed the led's on the clock and intermittently clicking and turning themselves on and off.......
