8. Demand control
Demand control is possible by applying a no-voltage a-contact continuous signal to the module controller.
Demand control can applied to "Electric current: A", "Capacity: %", "Rated power ratio: %", "Power
consumption ratio: %", or "Power: kW". Demand control limits the total of all modules in the system to no
greater than the demand control value programmed in the module controller. This limit is programmable
between the following values. Refer to "6-1 Heat pump control wiring diagram" when inputting to the module
controller. It can be set in 3 stages as shown in the table below.
Digital input
Demand input 1
Demand input 2
(Note) With the initial settings of digital input items, only "Demand input 1" is valid. When using "Demand input 2",
set the digital input item to "Demand input 2" and then set the corresponding input port.
