Refresh frequency: about 0.5S
Input power: 12V
Measurement input: 1 meter NTC (10K 0.5%) waterproof sensor
Output: All the way 10A relay
Environmental requirements: -10 ° ~ +60 ° Humidity 20% ~ 75%

Circuit connection:
The reference circuit is connected with the power supply and load. At this time, the digital tube (upper) shows the actual measured temperature, the digital tube (lower) shows the preset temperature. Missing or damaged temperature sensor The digital display shows "- - -" and the purchaser must check if the temperature sensor is installed before use.
The thermostat output 10A relay, to meet a variety of high-power load, make sure the line is correct.
LED, LED status Description:
Indicator: Off means the relay is off, it means the relay is on
Digital tube: display "- - -", 1, check the temperature sensor is missing or damaged 2, heating mode high temperature protection 3, cooling mode low temperature protection. In protection mode the relay is automatically disconnected.
The use of buttons: Thermostat panel has three buttons, buttons + button - set the button SET
Button +: to achieve rapid accumulation of values
Button -: to achieve the rapid decline in value
Restart: Restart the button
Set the key SET: to achieve two-tier interface settings temperature setting interface parameter settings interface
SET short press digital tube (down) to quickly set the temperature. Preset -20 °, 0 °, 20 °, 40 °, 60 °, 80 °, 100 ° and other data sets to facilitate the user to quickly call. For example: Users need to set 68.8 °, first short press SET adjusted to 60 °, and then through the key to add fine-tuning to the appropriate temperature. Set to wait 5s automatic memory to save data. Relative to the 1st generation thermostat 2 generation more convenient and flexible operation, dual LED display the measured temperature at the same time, set the temperature more easy to observe.
SET long press to enter the parameter setting interface, P0-P5 is the corresponding parameter setting item. Under the parameter setting menu, P0-P5 can be switched by pressing SET briefly. Want to modify a parameter just switch to the corresponding item, through the addition and subtraction button to set. After setting, press and hold SET to save the data, or wait 6s to save the data automatically.
Friendly Reminder:
P3 set to 1 that the thermostat operation for 1 minute to stop, press SET to trigger again.
P4 set to 1 that the thermostat 1 minute after the start of work. After setting the digital tube will not light, until 1 minute after the normal work. Press SET to trigger again.
The P5 default setting is OFF, and once the user has set the temperature, the P5 option can be set to ON in order to prevent others from changing it at will. Once set to ON data is locked, need to be set again when P5 needs to be OFF.
Knowledge Expansion: the concept of backtracking
Back to the simple understanding of the difference is to go back to the difference. Thermostat can be set heating and cooling two modes of work, so the backlash has two meanings:
In the cooling mode (when P0 = C), if the set temperature is 30 °, the hysteresis is 2, indicating that the actual temperature> = 32 °, the relay is closed, when the actual temperature <= 30 °, the relay is disconnected;
In the heating mode (P0 = H), if the set temperature is 30 °, the hysteresis is 2, indicating the actual temperature> = 30 °, the relay is off, when the actual temperature <= 28 ° closed.
