17.0 hydraulic system 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 MHS Boilers, or,
separate 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.
PS= Low water pressure cut off switch
Typical Multiple Strata 1 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.
System Type 6
