Looking to fine tune my settings.  Currently running about right keeping house warm around 20 to 20.5°C on the WC setting all TRVs open and thermostat turned above 30. Heat pump running continuously except for setback from 2100-0230 most nights.  Currently set flow temp OAT  -2°C is 40°C and 27.5°C at OAT 20 °C.  Now the outside temperature is slightly more temperate we are reaching 21.5 to 22.5°C in the evenings which is a bit warm.  Wondering whether to reduce the flow temp below 40°C or maybe reduce the temperature that that flow temp is achieved to say -4°C or perhaps reduce the flow temp at OAT of 20°C all of which should affect the WC settings and reduce the flow temperature compared with the current setting.  Any suggestions or tips gratefully received.  Thanks in advance. Mark.
