10 V: 2...50 kW
Boiler Output
At this point the maximum boiler output corresponding to the 10 V could be set.
P -‐Para: 0...50.0
Control Parameters
The P & I (tn) parameters of the 0 to 10 V output can be set here.
Tn: 0...500,0 Sec
Control Parameters
It is recommended not to change the preset parameters.
Example: Condensing Boiler – Giega Star from Giersch
(1) Boiler Output max:
30 kW
(2) Boiler Input min:
10 kW
(3) 0V:
0 kW
(4) 10V:
30 kW
P-Para:

I-Para:
15s
Ifthe boiler target temperature is either exceeded or not achived, the capacity
of the boiler output will be decreased or increased until the target temperature
is reached.
Attention
The modulation boiler control is only suitable with boilers who can be modulated
via 0-10 V output and do not independently modulate on their own.
Boiler Input
Temperature Target
Temperature Target: The CONTROL 602/702 transmits the calculated target
temperature via a voltage between 0-10 v using the control on the boiler. This
processes the voltage signal and modulates the boiler automatically to the
desired temperature. The modulation is done by the boiler conrtroller.
The following two menu items appear only in the Engineer’s menu with a boiler
operating with ‘Temperature Target’.
Note:
When setting ‘Temperature Target’, no speed control of store charging pump or
boiler pump can occur!
