6. Description of Each Control Operation
1. System Basic System
Dry mode
(1) Dry conditions and process:
a. When HUMIDITYpreset≤HUMIDITYamb.-5%, compressor and fan will run.
b. When HUMIDITYpreset≥HUMIDITYamb.+5%, compressor stop to run and fan will stop operation after 3min.
c. When DEHUMITYamb.-5% HUMIDITYpreset HUMIDITYamb.+5%, when compressor is operation, it will run with condition a;
when compressor stops, it will run with condition b.
(2) Humidity Range
a. 5% is one step, it can be adjusted continuously from CO, 35%-80% (CO stands for dehumidify continuously).
b. Adjust set temperature by "+" and "-".
2. Protection Function
(1) Working temperature range
a. Detect the unit after energized, when 4 ≤Tamb. ≤35 , the unit is running normally; when Tamb.
compressor stops, and fan will run with the detected temperature humidity;
b. During operation, when Tamb.
humidity; when 4 ≤Tamb. ≤35 , the compressor will be started up.
(2) Compressor Protection
a. After energization, under any situation and after compressor stops, it will restart 3min delay at least.
b. Under operation state except temperature sensor malfunction, on/off button, water-blow protection, after compressor starts up,
it will stop after it runs for 3min at least.
(3) Detection for temperature sensor malfunction
a. If ambient temperature sensor malfunction is detected, nixie tube displays "F1".
b. If pipe temperature sensor malfunction is detected, nixie tube displays "F2".
c. If these two temperature sensors malfunction are detected, nixie tube will display "F1" and "F2" in turn to remind customer.
(4) Water blow protection (off switch)
a. The water blow protection will be occurred when the water level of water tank is exceeded. After water blow protection,
compressor stops and fan stops after 3mins. If water blow protection occurred for 3min, the buzzer will stop after it gives out a
beep for 10s, indicator of water blow will blinks and all the buttons are invalid. When the water level or assembly of water tank
resume to normal, signal of water blow protection will cancelled, indicator is off, buzzer stops to give out a beep and resume to
normal operation state.
b. When the unit is off, water blow protection is occurred, buzzer will stop to beep after 10s, water blow indicator blinks,
compressor and fan stops, all the buttons are invalid.
3. Other Functions
(1) Power-off memory
Upon power failure, the unit after power recovery will automatically start to run according to memory content.
(2) Nixie tube display (green)
a. When the unit is running, it will display current humidity, set temperature will be adjusted by "+" or "-", it will resume current
humidity after the set is finished for 5s (if humidity is set, nixie tube displays "CO").
b. Under any situation and the temperature sensor is malfunction, nixie tube displays "F1" or "F2", timer lamp, continuous humidity
lamp, fan speed lamp and filter lamp will not display.
(3) Front panel button
On/off : turn on/off the unit
Timer: use for timer setting
+: Adjust humidity
