Remote control of boiler flow temperature?

No, Jonathan, any boiler that can continuously run at any SP can't have the control (SP) and the burner cut off at the same value, for obvious reasons, the boiler will modulate up or down to maintain the SP, if the heat demand falls below the boiler minimum output then the flow temperature will (have to) rise above the SP and when it reaches SP+5C, it trips the burner and the circ pump continues to run. When the flow temp falls to SP-5C the burner is enabled and will fire up when the anticycle time has elapsed.

Oil fired boilers which continuously cycle have burner trip at the SP and burner enablke at SP-hysteresis, nomally 10C.

Edit but yes to yout query as its SP+5, IE 95C
Thanks. I had no idea until joining this forum how different oil boilers were in various ways. Always assumed exactly the same, just different fuel.
