External pump is only used to push heating around, it is fitted next to boiler near manifold for ground floor.
Pipe coming from pump splits on TEE and goes down to ground manifold, and up to 1st floor manifold.0 -

No, only one pump.
no pumps on 1st floor.
Heating flow comes to manifold On 1st floor and from there into 3 bedrooms and bathroom with towel rail that is fed from manifold as well.
no rads on ground floor only ufh.
house is not big, i think that pump is enough, it is just that in winter temperature is very different between floors.
maybe it will better when i replace that valve and adjust bypass.0 -

just could not find how to turn the heating on, as it is still in summer mode.Have increased room temperature but still did not get any heating.I guess i have to wait till winter.0 -

Tried to adjust it but still not starting as return temperature is 25 and would start at 18. Have tried all settings .
was reading manual and it says that that gt8 and gt9 difference should be 7-10 c,
i have gt8@ 49.5 and gt9 @25.4, when boiler is in standby.Gt10 @13.2 and gt11@ 11.2 c. Manual says 2-4c, this one looks fine.Should change settings on heat carrier pump? Now it is on speed 2.0 -

GT8 and GT9 difference needs to be measured when it's operating, not on standby.0
