Precise system sizing, fine capacity control, maximum efficiency
Precise system sizing
The controller allows cascaded connection of up to 4 heat pumps to increase capacity delivered in applications with multiple occupied areas, such as hotels, schools, apartment blocks, offices and shopping centres.
Fine capacity control
Cascaded management of heat pumps increases the number of capacity control steps available, ensuring capacity responds to the effective trend in building thermal load.
Nadisystem can determine how many cascaded units are needed to guarantee domestic hot water production, all or just one, according to requirements.
Automatic rotation logic is applied to balance compressor operating hours. Continuous system operation is guaranteed by excluding any units that are momentarily out of service, without interrupting operation of the cascade as a whole.
