1 : has four operating modes , single and double control, all heating , cooling only , within the limit outside limit control mode

2 : Number of automatic recognition sensor and automatic distribution , digital display temperature.

3 : can be accessed by road DS18B20, or 2-way DS18B20

4: upper and lower temperature adjustable, with adjustable hysteresis settings are automatically saved in eeprom

5: with two -way relay control and instruction .

6: 5-24V power supply available

 

Our latest design, dual digital temperature controller / monitor, the strongest performance of the entire network, convenient and user-friendly operation, industrial control, sheds, DIY fridge oven, vegetable greenhouses, greenhouses, Incubator, fish tanks, and personal production, etc. choice
Main features:


1. Dual precision waterproof digital probe DS18B20, really reach 0.1 ℃ accuracy. (Any thermistor probes are the most accurate only 1 ℃, the so-called 0.1 ℃ is made out of fake software effect.)
2. Dual control relay, 10A / 250V power output.
3. The total of 4 operating modes can be combined: one cooling / heating all the way, all dual refrigeration, heating dual whole, single heating and cooling dual control. Really meet your control needs in a variety of situations.
4. 5-24V Wide supply voltage input: either the USB 5V or industrial control 24V, this controller capability, truly the most widely applicable, no longer have to worry about power supply. Bright blue LED power indicator, beautiful eye-catching.
5. Highlight four red LED display, clearly visible with degrees C symbols, true 0.1 ℃ accuracy.
6. Set Menu maximize simplify and retain all the functions, with red yellow 3 LED, convenient and user-friendly operation, no longer have to remember complicated codes.
7. Each relay comes purple LED indication, opened disconnect clear, easy to control the working status.
8. Power input reverse polarity protection, reversed when the controller does not work, no longer have to worry about the effect that burned equipment.
9. Support temperature monitor mode for controlling the device to work in a certain temperature range, avoid temperature extremes cause accidents.
Our exclusive design, peers do not copy, the product factory direct, accept bulk orders, bulk delivery period of 10-15 days.
Wiring: Power supply side: + is positive, - is negative, it can be directly powered directly by DC power cord. The power cord, flat poke pipe appropriated the right to use.

 

I. Features
1 , has four operating modes, single and double channel heating and cooling mode ; full heating mode ; full cooling mode ; dual control mode ;
2 , can detect and display two temperature
3 , the power automatically identify the number of temperature sensors
4 , dual 230V 10A relay quality control (can be used to control peripheral load , such as : heating , cooling)
5 , power is automatically stored setting parameters (MCU built-in EEPROM memory cell )
6, the control accuracy of 0.1 degrees Celsius
7 , hysteresis 0.0 from setting , step 0.1 degrees Celsius ( 0.0-20.0 )
8 , wide input voltage range can DC5-24V

 

Boot process

Connect the power supply and the equipment, the controller can supply (5-24V power supply)
The boot detection sensor into the situation
No sensor is inserted, the display shows 0000 and accompanied by LED1, LED2, LED3 flashes.
A sensor is inserted, the controller automatically reads the stored parameters
Then show the preset temperature A, the red LED flashes 3 times (LED1).
B then show the preset temperature value, the blue LED flashes 3 times (LED2).
The last display mode, the yellow LED blinks 3 times (LED3).
 
After displaying the measured temperature
If there are two sensors, the two take turns measuring temperature 1S, DS1 temperature display XX.XC, LED1 on, other off; DS2 temperature display XX.Xc, LED2 light, other off
 
Parameter setting method
Press the SET button, LED1 starts blinking, the display shows the set temperature A, press T ++ T-- to set the desired temperature A. Display template xx.xC
Press the SET button, LED1 starts blinking, the display shows the set temperature A return difference, according to the set temperature T ++ T-- A return difference. Display template H x.x
A channel setting, or press the SET 3S waiting to enter B channel settings.
Press the SET button, LED2 starts blinking, the display shows the set temperature B, according to T ++ T-- to set the desired temperature B. Display template xx.xC
Press the SET button, LED2 starts blinking, the display shows the difference between the set temperature B back, press T ++ T-- B back to the set temperature difference. Display template L x.x
B channel setup is complete, wait 3S or press the SET button to enter working mode.
Press the SET button, LED3 starts blinking, display mode, press T ++ T-- to set the operating mode (1: single and dual channel heating and cooling mode; 2: Full heating; 3: cooling only; 4: dual control mode) . Displayed as PP x. All parameters are saved automatically.
Press SET to exit the setup, LED all off, shows the actual measured temperature, then the system automatically saves parameter settings, work has begun to enter the corresponding mode.
      
Special Note: After SET, T ++, T-- key settings, no key action within 4s, the system saves the parameters of the current settings, and then shows the measured temperature and enter the working mode. Press the button, the key automatically.
 
V. Work Mode Description
Mode 1: single and dual channel heating and cooling mode
       
DS1 and DS2 temperature alone,
       
DS1 can be used in heating mode at this time, when the temperature is below the set temperature DS1 A, closing relay JQ1 accompanied indicator A lights. When DS1 temperature> set temperature A + A return temperature difference, relay JQ1 off, the indicator A off.
 
       
DS2 can be used in cooling mode at this time, when the temperature is higher than the set temperature DS2 B, relay JQ2 closed and accompanying indicator B lights. When DS2 temperature  
Mode 2: Full heating mode
       
DS1 and DS2 temperature alone,
       
DS1 can be used in heating mode at this time, when the temperature is below the set temperature DS1 A, closing relay JQ1 accompanied indicator A lights. When DS1 temperature> set temperature A + A return temperature difference, relay JQ1 off, the indicator A off.
 
       
DS2 can be used in heating mode at this time, when the temperature is below the set temperature DS2 B, relay JQ2 closed and accompanying indicator B lights. When DS2 temperature> Set temperature B + B return temperature difference, the relay JQ2 off, indicator B is off.
 
Mode 3: Full cooling mode
       
DS1 and DS2 temperature alone,
       
DS1 can be used for cooling mode at this time, when the temperature is higher than the set temperature DS1 A, closing relay JQ1 accompanied indicator A lights. When DS1 temperature  
       
DS2 can be used in cooling mode at this time, when the temperature is higher than the set temperature DS2 B, relay JQ2 closed and accompanying indicator B lights. When DS2 temperature  
Mode 4: dual control mode
       
DS1 and DS2 temperature can only use one,
       
At this point DS1 (or DS2) may be used to dual-control mode, when DS1DS1 (or DS2) A temperature higher than the set temperature, the relay closes JQ1 accompanied indicator A lights. When DS1 temperature  
       
When DS1 (or DS2) temperature is below the set temperature B, the relay closes JQ2 accompanied indicator B lights. When DS1 (or DS2) temperature> Set temperature B + B return temperature difference, the relay JQ2 off, the indicator B is off.
