B For ALARM terminal port CN33
1. Provide the terminal port to connect ALARM, but no voltage of the terminal port, the power from the
ALARM system (not from the unit )
2. Although design voltage can support higher voltage, but we strongly ask you connect the power less
than 24V, current less than 0.5A
3. When the unit occurs the problem, the relay would be closed, then ALARM works
C. For remote control (ON-OFF) terminal port CN23 and short connector of J7
1. Remove the short connector of J7 when you use ON-OFF function;
2. When remote switch off (OPEN), the unit would be off;
3. When remote switch on (CLOSE), the unit would be on;
4. When close/open the remote switch, the unit would be responded the demand within 2 seconds;
5. When the remote switch on. You can use remote controller/wire controller to select the mode what
you want; when the remote switch off, the unit would not respond the demand from remote
controller/wire controller.
When the remote switch off, but the remote controller / wire controller are on, CP code would be
shown on the display board.
6. The voltage of the port is 12V DC, design Max. current is 5mA.
