I replaced several month ago my single zone thermostat with the evohome system. In a first time I left the previous boiler control (3-way mixing valve with weather compensation) but I had to set the temp slope pretty high to have good regulation in the north room.
Now I want to upgrade the system because the high boiler output temp (65-70d) increases the losses in the walls, pipes (my installation is not well isolated and inside some rooms, the domestic COLD water becomes warm due to proximity with radiator pipes (!)).
All the "evohome proposals" I could read are based on a ON/OFF boiler control that does not sounds good to me. (Y plan, S plan or simple relay Wo domestic water).
I know that the mixing valve controller HM80 is compatible with the evohome system, but can it be used to adjust the boiler heat demand?
Did somebody tried it, or is there any doc available?
Best regards and many thanks for the help
