(3) Duty signal control
Capacity control: The capacity of outdoor unit is fixed by an external duty signal, which can be a free-voltage
signal (0~10V or 0~5V) or a current signal (4~20 mA). The duty signal is generated by a field-supplied DDC
and supplied to the AHU Connection Kit.The capacity of outdoor unit depends on the signal strength.
Thermostat control: for system controlled by a duty signal it is possible to force thermo-off by the duty signal
itself. When the duty signal becomes lower than 8% of the full range of the signal,the system will be turned
to thermo-off condition.When the duty signal becomes higher than 14% of the full range,the system will be
turned to thermo-on condition.
