1 OF 7 WUXI HUTEC Functional Specification Product： Dehumidifier Remote-Control Type： HJ-CSJ63/64/65/66/81/82 Customer： W C Wood Company Limited Rev: A By： Jimmy.Liu Date： 26th Aug，2005 Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. A. Brief There are three parts of the Dehumidifier Remote-Control. a. Electrical source board (Same as the normal dehumidifier: 4-75517-101， 4-75517-102) - Voltage rage: 115VAC / 60Hz，220AC /50Hz b. Receiving-Control(HJ-CSJ63/64/65/66) - Receiving-Control receives the instruction from the Transmitting-Control and controls the fan and compressor to be on or off. c. Transmitting-Control(HJ-CSJ81/82) - User sets the RH on Transmitting-Control, and the Transmitting-Control emits the instruction to Receiving-Control to open or close compressor according to the ambient RH and user’s RH set-point. - In order to save power, the transmitting-control sleeps 57s and wakes up 3s per minute normally. In sleep status, the transmitting-control does nothing , not tests the RH or temperature ,not emits instruction to Receiving-control, not changes the LCD. So the current is lower than 80uA in sleep status. You can wake up transmitting-control by pressing any key while it’s in sleep status. While time reaches per minute or user presses any key , the transmitting-control wakes up. In wake up status, transmitting-control tests the RH and the temperature, then it decides what to do. The current is about 4mA in wake up status. - The distance of the remote is about 15m indoors or above 20m outdoors. B. Functional Specification 2 OF 7 Part a Electrical source board Same as the normal dehumidifier: 4-75517-101，4-75517-102,not described here. Part b Receiving-Control Four Led Lights: Fan-speed-high light (LED1), Fan-speed-low light (LED2), Power-on light (LED3), Bucket-full light (LED4.RED)/Low-temp light (LED4.GREEN) TWO Buttons: Power button(SW1), Fan-speed button(SW2) TWO Temperature sensors: ambient-temperature sensor, coil-temperature sensor ONE Buzzer: bucket-full alarm Figure.1 Receiving-Control 1. Normal mode 1) When first time turning on power to the receiving-control, the receiving-control begin to work with the power-on light on according to the instruction from the transmitting-control. If the remote communicates error for 30 minutes, the power-on light flashes and the audible alarm (Bi-Bi) will be generated. After communicate error, you can press Power button and Fan-speed button at receiving-control. Fan will run at the speed according to your selection. Compressor will keep on for 52 minutes and keep off for 8 minutes. 2) When the fan speed is chosen high on the transmitting-control, the fan-speed-high light is on and the high-speed fan runs if it is enable. When the fan speed is chosen low on the transmitting-control, the fan-speed-low light is on and the low-speed fan runs if it is enable 3) Compressor must lag behind fan for 4 minutes. Once the compressor quits running, it needs 4 minutes of interval if it should be turn on again. 4) When bucket full condition is detected for 2 seconds, compressor & fan will be turned off sequentially. Then bucket-full light will be on and the audible alarm (1s on/1s off) will be generated every hour. 5) The buzzer is able to alarm only because being set enable from transmitting-control. 3 OF 7 2. Very-Low-temp mode If ambient temperature is below 4’C for 4mins, the control stops, the four LED lights flash until the ambient temp is above 5’C for 8mins. 3. Low-temp mode When the ambient temperature is lower than 15’C and lasts over 10 minutes continuously, the receiving-control will automatically enter into the low-temp mode and the low-temp light begins flash. In the low-temp mode, there are two conditions: Condition A: If humidity does not reach your set point, the compressor runs 52mins on/8mins off. At the end of the cycle, the receiving-control checks the coil-temp. If the coil-temp is above 5’C, the compressor continues 52mins on until the humidity reach the Set-point. If the coil-temp is below 5’C, the compressor keeps stopping and fan runs to defrost for 8mins again. At the end of the cycle, check the coil-temp again. Condition B: If humidity reaches the set point in 52mins, the compressor stops and the fan runs, the receiving-control runs defrost for 4mins. at the end of the 4mins, check the coil-temp. If the coil-temp is above 5’C, the compressor and the fan keep stopping unless humidity increases to the set point again. If the coil-temp is below 5’C, the receiving-control runs defrost for 4mins again, and then check the coil-temp. Once the ambient temperature is above 18’C for 10mins, the remote enter the normal-mode. 4. Defrost mode: When the coil temperature falls below 2’C more than 10 minutes, the receiving-control will automatically enter ‘Defrost mode’. In ‘Defrost Mode’, the compressor will be turned off, the fan will continue running with the selected fan speed. The compressor remains off until coil temperature rises to 9’c or higher more than 10 minutes. (Note: the defrost point is not decide, maybe is 2’C and 9’C, 4’C and 10’C, 6’C and 11’C.) 5. Fail-safe mode If the coil temperature sensor and ambient temperature sensor fail to work properly, the control will run in a fail-safe mode. The fan will run at the speed you select and the compressor will cycle with 52 minutes on / 8 minutes off sequence. 6. Self-test mode While power is off, press Fan-speed button and Power button at the same time for 3 seconds, you will see all LED light on and the buzzer alarms for 1 sec. It means the 4 OF 7 receiving-control has entered the self-test mode. Then you can test the parts of the receiving-control one by one. Press fan-speed button, fan-speed-high light is on and high speed fan runs. Press fan-speed button, fan-speed-low light is on and low speed fan runs. Press fan-speed button, power-on light is on and compressor &…
