Main Application
1. Two Pipe AHU
• Cooling/Heating changeover
– Setting point is positioned in the mid of
proportional band
– AO is proportional to the temperature
measured
– Changeover is adjusted by manual
• Emergency Interlock
– Under normal status, DI is closed. If
emergency happens, DI open. The
controller will reset all output, then cut
off the power.
– The controller only can be restarted by
manual operation

exchanger temperature limit control
– Heating is modulating output and
proportional to measured
temperature
– Heating setpoint is in the mid of
proportional band
– The temperature limit setpoint is
separate from the heating setpoint
– If the measured temperature is over
than temperature limit, the system
alarm is on

Configuration & Operation
Item Operation Display
Power On/Off • Connect the main power. Display screen shows “DIGIT IN” and “OFF”.
•Press the ‘SELECT’ key and hold more than 3 seconds, the controller turns on. It will read the setting value
in EPROM automatically. The controller is powered on.
• After power on, LCD screen displays ambient temperature, output2 shows “DO OPEN”.
• Press “select” key and hold more than 3 seconds, the product is powered off. And the display shows “OFF”.
Temperature
Adjustment
• Press key Sone time, the setting temperature will be 10C up. Press and hold the key more than 2
seconds, the temperature increases continuously until reaches 600C(internal sensor) or 1100C(remote
sensor). Press the button one more time to stop the temperature change.
• Press the key Tone time, setting temperature will be10C down. Press it and hold more than 2 seconds,
the temperature decreases continuously until reaches 100C(internal sensor) or -200C(remote sensor).
Press the button one more time, the temperate change stops.
