Appliance description

The cascade module (KM) comprises a cascade control for

switching and modulating boilers. Only boilers of the same type

(single stage, two-stage or modulating) and of the same output

may be linked in a single cascade. The active boilers transfer the

generated heat into the low loss header or the heating system

headers, whereby the heat is captured by the header sensor, the

so-called common ow sensor of the heating system.

The KM module also comprises a mixer circuit control and the

control for a programmable output. The mixer circuit controller

can be used for the heating ow as well as for the heating return.

The programmable output either regulates a direct heating circuit,

a cylinder circuit, a convector heater (= ext. heat demand), or a

three-way diverter valve for raising the return temperature (= central

heating backup). The outputs for the mixer circuit control can

also be congured as DHW circulation pump and fault message

output. Subject to application, select the relevant combination of

mixer circuit controller or outputs and the programmable output

as conguration.

For connection to telecontrol systems, the KM offers a 0 to 10 V

input with which to control the boilers. With this conguration only

the fault message output is still enabled.

Parameters can be changed and sensor values can be displayed

at the programming module (BM) or at ISM1 with WRS-Soft. The

KM features an eBUS interface (2-wire communication BUS) and

can therefore be integrated into the Wolf control system.
