When there are only 4 channels of inputs, SUB1 cannot be used for alarm output but heating/cooling control only.
**
When there are only 4 channels of inputs, OUT2 and SUB2 cannot be set up by the user but set up automatically as "alarm output” by the
controller.
Control Output:
DTE offers PID control, ON/OFF control, manual control and programmable PID control. Control output methods are set at address H10B8 ~
H10BF (default = 0: PID), PID parameters at H1028 ~ H105F, ON/OFF parameters at H1058 ~ H106F, and manual control parameters at
H1070 ~ H107F.
Alarm Output:
DTE offers 13 alarm modes. The alarm modes are set up at address H10C0 ~ H10C7, upper limits at H1080 ~ H1087 and lower limits at
H1088 ~ H108F.
