5.7.7 cascade controller KKM2

The KKM2 Cascade Manager is available as an accessory (see fig 5.7f). The cascade controller can

operate up to 5 units. On a load dependant basis, it controls the modulation of the burners, and the

switching of the appliance(s). It includes all necessary sensors and an external temperature control which

adjusts the flow temperature of the cascade system as a function of the outside air temperature and/or

the sensed room temperature via the RE 2132 (if required) or 0-3 or 0-10v input. The KKM2 may also be

set to give a constant flow temperature and can also control a domestic hot water circuit.

Other types of cascade controllers with a continuous 0 to 3V, or 0 to 10V signal can also be connected.

An optional adapter is required, for 0 to 10V. See Fig 5.7e (Below)
