Cascade manager KKM8
The R600 can be equipped with a
KKM8 cascade manager for cascade
control of up to 8 boilers, in combinati-
on with weather compensated control
of two heating zones and sanitary hot
water production. The KKM8 combines
all functions of the E8 with an intelligent
cascade control, which allows free pro-
gramming of boiler sequence after cer-
tain hours of operation.

The KKM8 can also be used for casca-
de control only, without using the possi-
bility to control secundary heating zo-
nes. An external temperature setpoint
0-10VDC can be connected directly to
the KKM8, the value of the signal can
be programmed into the KKM8.
For room temperature optimisation of
each heating zone, an additional roo-
munit BM8 can be connected via bus
connection. The values for the specific
heating zone can then be displayed
and changed on the room unit.
In case of heating systems with more
than two heating zones, an additonal kit
with E8 in a wall hung box is available.
These kits can be used in a modular
way up to a maximum of 15 heating
zones.
