PV line is designed to be a four-digit nixie tube. In normal condition, it shows temperature of control target and in event of alarm, it shows malfunction code:
SP line is designed to be a four-digit nixie tube. In normal condition, it shows setting temperature:
Three indicators are soft start indicator, automatic operation indicator and manual indicator from left to right.
After initial power on, system enters soft start status. Dehumidify heating ring. Output power and operation time of soft start can be set up by menu. When soft start, this indicator flashes.
When system enter automatic constant temperature operation status, this indicator flashes.
When system enters manual operation status, this indicator flashes

Status transition and display
After power on the controller, if initial target temperature is lower than 100 and it is in soft start mode, then system enters soft start mode automatically. If system is in soft start mode after starting up, flashes in every second. Soft start time and output power can be set up in the menu.
When soft start is over, it enters automatic operation mode and flashes in every second. After system power on, if it is detected that target value is higher than 100 degree or soft start mode is off, then it enters automatic operation mode.
In automatic operation status, long press to enter manual state.
In manual status, long press to return to automatic operation state.
In manual operation status, flashes in every second.
In manual operation status, SV screen shows manual output power, SP shows current state. Method of manual output power is the same as temperature setup .

Generally, AP is ON.
When AP is ON, controller tests heater functions automatically during each power on and temperature rise. When temperature controller gets accurate heater parameter, it performs accurate control.
When AP is OFF, controller will not test heater function, but withdraw parameter from previous record. If temperature controller controls the same heating ring, it is stable.
