Power peak-cut from indoor unit
When the relay is turned on, a forced thermostat OFF operation starts.
• For indoor P.C. boards other than MCC-1643, the “EXCT” is input with connector CN73 on the P.C. board.
MCC-1643 requires Application control kit (TCB-PCUC2E) for input of a forced thermostat OFF “EXCT”.
Please refer to the manual of Application control kit for a detailed setting.
Note)
Determine the cable length between the indoor or
outdoor control P.C. board and the relay within 2 m.
