5.13 Systems that can be controlled
Sime ALU PLUS HE boilers can control many types of systems.
Here are some system diagrams, by way of example, in which
the boiler can be a single appliance or a group of cascading
boilers which can considered as a single appliance in terms of
heat output, where Cascade output = Boiler output x no. of boilers
installed .

CAUTION
When systems using ALU PLUS HE single or cascade
boilers are managed by MODBUS systems,
Sime
kits
CANNOT be used to manage mixed circuits or the
solar circuit. You MUST use external devices.
