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).
