Input temperature eont increase.

Hi All.

 

I have a Ecodan ASHP connected to an underfloor system.

 

On controller the flow input temperature target is set to 45 but after a few hours it can't get past 40 degrees. What can cause this and what's the solution. 

 

I have a second of the floor that's pretty cold yet the loop has 1.5l fliw rate. What would cause this .

 

Last up the differential pressure bypass value seems to be fitted upside down. What effect would this have on the system? ( see pic) 

 

Thanks

If you have a buffer you may well get a temperature drop across the buffer so will have to compensate.

 

Increase your second floor flow rate, that will increase the mean flow temperature to increase energy input to the room.
