design
OS = Outside air temperature sensor, used where direct-on-boiler weather
compensated flow temperatures are required.
C = Room temperature controls e.g. RE2132 modulating room unit from RVR Ltd.,
or, separated time clock & room thermostat.
FS = Flow temperature sensor
RS = Return temperature sensor
S = Hot water temperature sensor or thermostat.
KKM2 = Modulating Kaskade Manager. Up to 9Nr boilers may be controlled using
2Nr linked KKm2’s.
System type 6
Typical Multiple MICROMAT EC installation. Boilers controlled by modulating Kaskade manager which also has the
facility to control heating & domestic hot water production. Heating flow temperature may be fixed/constant or weather
variable. Hot water has priority.
