Adjusting the heating curves
The heating curves illustrate the relation-
ship between the outside temperature
and the boiler water or flow tempera-
ture.
To put it simply, the lower the outside
temperature, the higher the boiler water
or flow temperature.
The room temperature, again, depends
on the boiler water or the flow tempera-
ture.
Note
If the heating system includes heating
circuits with mixers, then the flow tem-
perature of the heating circuit without
mixer is higher by a selected differential
(8 K in the delivered condition) than the
flow temperature of the heating circuits
with mixers.
The differential temperature can be
changed at coding address 9F.
Settings in the delivered condition:
■ Slope = 1.4
■ Level = 0
