5.2.4 Pump management (CO1 F09)
You can use the optional binary outputs BO1
and BO2 to control a two-stage heating cir-
cuit pump. In the periods of non-use, the heat-
ing circuit pump is reduced to its minimum
rotational speed.
The binary outputs BO1 and BO2 have the
following function:
4
BO1: Heating circuit pump on/off
4
BO2: Activate rotational speed
The contact positions of BO1 are determined
as follows: if the heating pump is to run,
BO1 is closed.
You can configure the binary output BO2 like
this:
CO1 F09-1: BO2 = Off when not used
(binary output open)
CO1 F09-0: BO2 = On when not used
For the switching positions of the pumps,
please refer to the installation manual of the
relevant pump manufacturer.
Note: BO1 to BO3 are optional. They cannot
be retrofitted.
5.2.5 Collective error message (CO-SYS F13)
If you activate function block CO-SYS F13-1,
binary output BO3 is set in case of an error.
Errors are also displayed on the information
level on level " Err ". For an overview of the
error messages, refer to page 62.
Note: BO1 to BO 3 are optional. They can-
not be retrofitted.
5.3 Time-controlled functions
5.3.1 Time, date, year (PA-SYS)
The heating controller is basically ready for
operation with the factory settings, however,
you are required to enter the current time
and date. How to enter the time and date is
described on page 20 ff.
5.3.2 Delayed outdoor temperature adaptation (CO1 F05)
Use the function block CO1 F05 to acti-
vate/deactivate the delayed outdoor tempera-
ture adaptation. This function helps to pre-
vent heating center overloads in combination
with overheated buildings, or temporarily
insufficient heating due to short-term outdoor
temperature variations, e.g. caused by warm
winds or excessive solar radiation to the out-
door temperature sensors.
For the temperature adaptation, a ‘calculated
outdoor temperature’ is used: If the outdoor
temperature changes within very short peri-
ods, these variations are considered only to
a certain degree which is defined by the func-
tion block parameter ‘Delay’. If this function
block parameter is set to 3 °C/h (factory set-
ting) and the outdoor temperature changes,
for instance, by 4 °C within one hour, a vari-
