Operation
The upper limit capacity of the outdoor unit is restricted
based on the demand request signal from outside.
L1 : Display lamp during power peak-cut control
SW1 : Power peak-cut ON switch
(ON during demand, OFF in normal time) ∗1
SW2 : Power peak-cut OFF switch
(OFF during demand, ON in normal time) ∗1
*1
Input signals of SW1 and SW2 are acceptable even if they
are longer then pulse input (100mm.sec.) or serially made.
However do not turn on SW1 and SW2 simultaneously.
∗ Be sure to prepare a contact for each terminal.
Relay contact capacity of “operation” port
Below AC240V 0.5A (COSØ = 100%)
Below DC24V 1A (Non-inductive load)
Note) When connecting non-inductive load such as relay
coil to L1 load, insert the noise surge absorber CR
(In case of AC) or counter electromotive-proof diode
(In case of DC) into the bypass circuit.
Power peak-cut control board: TCB-PCDM2E
Outdoor unit destination to be connected becomes the
header outdoor unit (U1).
