System versions overview
System version 1: Outdoor reset heating controller
(FW200, FB100)
An advantage of this system is the ability of the modules
to communicate, enabling all heating zones to be
controlled with the ICM module. This ensures matching
the generated heat amount to the actual heat demand of
all heating zones in the system. With this version, the
heating system achieves optimum comfort with
maximum energy savings.
System version 2: 0 - 10 V controlling boiler modulation
P [%]
In conjunction with a building management system with
0 - 10 V output, the total output of the cascade is
controlled based on the voltage input (

• Outdoor temperature sensor F.
• Common supply temperature sensor to
terminals J.
• Heating pump (secondary zone).
• Common supply temperature sensor on
terminal E (only for internal frost protection).
• Heating pump (secondary zone) (
[19]) on terminal C, only with one or several
heating zones without heating pump or with
heating zones that are not controlled by the
building management system.
• Common supply temperature sensor on
terminal E.
• Heating pump (secondary zone) (
[19]) on terminal C, only with one or several
heating zones without heating pump or with
heating zones that are not controlled by the
building management system.
• Common supply temperature sensor on
terminal E (only for internal frost protection).
