Operation process

1.Key Setting Function

  

Key1 to Key 5 is counted from left to right;

Key No.1	Key No.2	Key No.3	Key No. 4	Key No.5
Clock set	Mode switch	Trigger set/Setting bit switch	Value +	Value -

2.Key-setting function Instruction

Key	Definition	Description
Key No.3	Trigger set/setting bit switch	After power-up, short press this key to enter setup mode, LCD backlight will light up. If no other key is pressed within 4 seconds, it will automatically exit the setting mode and trigger the wireless data transmission. In setting the alarm threshold mode, pressing this key will switch the high and low bits of the value. In the clock setting mode, the clock's minutes and seconds can be switched and the threshold value can be quickly set.
Key No.2	Mode switch	In the setting mode, short press the key will cycle into following setting scenario: the upper temperature threshold, the lower temperature threshold, the temperature alarm back-off value, the humidity upper threshold, the humidity lower threshold, and the humidity alarm back-off value. In any of these scenarios, various thresholds can be quickly set by pressing key No. 3, No. 4 and No.5
Key No.4	Value +	Temperature plus/minus sign bit/ increment of selected value（0~9）
Key No. 5	Value -	Temperature plus/minus sign bit/decrement of selected value（0~9）
Key No. 1	Clock set	In the setting mode, enter the clock setting function, the clock is 24 hours

3.Key setting temperature upper/lower threshold, humidity upper/lower threshold, temperature alarm back-off value, humidity alarm back-off value, real time clock

3.1 Key setting temperature or humidity upper limit alarm threshold

• Setting step 1: Press key No.3 shortly to enter key setting mode. At this time, the LCD backlight is lit.
• Step 2: Shortly press key No.2 to switch the setting items.The positive/negative sign of the temperature/humidity upper limit alarm value starts to flash, and the upper triangle mark appears.
• Step 3: Shortly press key No.3 to quickly switch the ten, one and decimal places of the set value.
• Step 4: Shortly press key NO.4 or key No.5 to increase/decrease the set value.

3.2 Key setting temperature or humidity lower limit alarm threshold

• Setting step 1: Press key No.3 shortly to enter key setting mode. At this time, the LCD backlight is lit.
• Step 2: Shortly press key No.2 to switch the setting items.The positive/negative sign of the temperature/humidity upper limit alarm value starts to flash, and the lower triangle mark appears.
• Step 3: Shortly press key No.3 to quickly switch the ten, one and decimal places of the set value.
• Step 4: Shortly press key No.4 or key No.5 to increase/decrease the set value.

3.3 Key setting the temperature or humidity alarm return threshold

• Setting step 1: Press key No.3 shortly to enter key settinmode. At this time, the LCD backlight is lit.
• Step 2: Shortly press key No.2 to switch the setting items.The tens digit of the temperature/humidity alarm back-off threshold starts to flash, and the up/down triangle mark appears.
• Step 3: Shortly press key No.3 to quickly switch the ten,one, and decimal places of the set value.
• Step 4: Shortly press key No.4 or key No.5 to increase/decrease the set value.

3.4 Key setting the real-time time

• Setting step 1: Press key No.3 shortly to enter key setting mode. At this time, the LCD backlight is lit.
• Setting step 2: Shortly press key No.1 to enter the clock setting mode, and tens digits of the hour flash.
• Setting step 3: Shortly press key No.3 to quickly switc the tens digits and units digit of the set value
• Setting step 4: Shortly press key No.4 or key No.5 to increase/decrease the set value
