Ok amazing thanks - ill balance it out then to whats sensible.. Is there any benefit of the system being at 1.5bar rather than 1bar apart from the operating restrictions of Heat Exchanger etc?

Thanks thats what i thought, so financially im better off having the water as hot as possible under the floor as ive already paid for the cost of heating it

Ok turned out that i wasnt going mad and i had a temperamental valve thats now been replaced, therefore trying to get the thing setup efficiently if anyone knows the answers to the following? With district heat do i pay for the water amount? Or the cost of heating the water? If its just the water amount then i guess i want the water as hot as possible? I have the current water temp set to 50c into the manifold (combo of engineered wood and carpet) presumably i should increase this until my floor temp is 27c? Should the pipe thermostat be on the flow or return on the manifold? Also i seems to be tripping out at 40c which doesnt make sense as the water going is 50c Is there any advantage to having the pressure set to 1.5bar rather than 1bar (which is what the other flats seem to be at) even though EON say it should be 1.5 Thanks

Yes the thermo activator is opened (black bit in middle is raised when requested)

Thanks so not venting using the pump but the actual heat exchanger part? All the valves are open so guess it must be an air issue

Its now showing 0.027 m over h and 0.280 k W What should these values read when its operating? Then dropped to 0.000 Lost

Yeah the flow meters are showing at 2 - have turned off all but 1 room to isolate, i can hear the pump going as well

All showing at 2m /l as thermostats on in all rooms and actuators are open

34591 k Wh 0.008 m over h 0.059 k W 48 over an l - 42 over celcius dt 6.3 celcius

Yes have all the settings and put the flow meters back to original - the flow meters are showing flow however the pipes are all cold Will check all the Sonometer settings and report back

Thanks @John Carroll I thought you had as well (weird) and your advice and reading manuals i understand the flow control and pumps however whilst i was working that out i seem to have gone backwards, when trying to work out how it all worked i took off ATP Pipe Thermostat off the Manifold not realising what it did. The ATP Pipe Thermostat is back on the flow meter Manifold and set to 60c Not sure if thats caused the issue but the Heat Exchanger for the UFH is stone cold, Whilst the Heat Exchanger for the water is hot and working The pipe out of the UFH Heat Exchanger into the Manifold is also cold and reading 15c The pipe that feeds into the Differential Pressure Controller is hot (and then its difficult to tell due to thicker pipes but by time its gone through the RAVK Controller and the Thermo Activator its cold The Thermo Activator i think is ok, it says its naturally closed, and when i shut down power the black middle bit of plastic goes down, and when i power back up and the polypipe controller kicks in it gradually protrudes out Picture below, but i cant work out what to do next This is the system https://assets.danfoss.com/documents/353645/AQ082486478026en-010501.pdf Thanks again

I presume it is the mixing valve as per 6.2.1 IHPT 90 controller (45–65 °) and therefore i have set to the fully - position and then turned towards + 5 times to get to 48c which i presume is what i should of done

This is the system https://assets.danfoss.com/documents/353645/AQ082486478026en-010501.pdf

Set it back to 1 on grunfos temp as seemed to have gone backwards as getting no heat through, the actuators are warm, but the supply and flow pipes are stone cold and the Pipe thermostat into the Manifold is reading at about 18c Do you know what the + - valve on the right of the pump is likely to be and controlling is the the mixer or the release valve maybe?.. I have tried turning it fully to + and i can either hear water or air, however turning it back a few turns and the sound disapears

The Grunfos thing - Yeah it doesnt display anything just a load of settings that ive just changed from PP1 to CP1
