3: DC current
(5) Alarm output ------------------------------- 1: 1 point (1a)
2: 2 points (1a+1a)
(Alarm type and Energized/Deenergized can be selected by key
operation)
(If 2 points of alarm are selected, Heating/Cooling control cannot
be added.)
(6) Heating/Cooling control (OUT2) --------- 0: Not available
1: Relay contact
2: Non-contact voltage (for SSR drive)
