Weather compensation
If the boiler’s heating curve is set to have the
radiator thermostats on comfort temperature
constantly, the curve must be increased in order
to be able to raise the room temperature after a
setback period.
• If the setback periods are long, further
increase might be necessary.
• If the economy periods are short, less in-
crease can be sufficient.
