5.4.5 Optimize (CO1 F02)
If the function ‘Optimize’ has been activated,
the heating controller determines the most
favorable time points for activation/deactiva-
tion in order to already reach the desired
temperatures just when the time-of-use starts
and to maintain the temperature just until the
end of the time-of-use. For this function, the
controller either uses stored data about the
building characteristic or a preset maximum
preheating time. During the preheating time,
requests for drinking water are not pro-
cessed. To activate the ‘Optimize’ function,
select function block Fb02-1 on the configura-
tion level CO1. After this, you must select
one of the three optimizing modes described
below (1, 2, or 3). If you did not select a
room sensor, i.e. CO1 Fb01-0, you can only
choose Optimizing mode 1.
Optimizing mode 1 (without room sensor)
The activation point of time of the heating
system depends on the outdoor temperature.
For this, you are required to adjust the maxi-
mum permissible ‘Preheating time’ (function
block parameter) at an outdoor temperature
of
−
12
°
C, factory setting is 120 min. When
higher outdoor temperatures prevail, the pre-
heating time is reduced. During the time of
non-use, the heating controller is in reduced
operation as described in chapter 5.4.2.
