          *1 Can be set for each channel.
          *2 Because the alarm output is used as cooling control output when heat/cool control is used, the alarm output cannot be used as an alarm output function.
          *3 Standby operation ON/OFF can be selected in each alarm mode.
          *4 Use a KEYENCE sensor (OP-6694). (Sold separately.)
