1.1 Automatic Mode Function Description


1) Firstly, select heating mode/cooling mode;


2) Set the temperature and return difference. If a delayed start is required, set the time for delayed start


3) If high and low temperature alarms need to be set, set the high and low temperature alarm threshold yourself

1.2 Heating mode description


When the detected temperature (current temperature) is ≤ the set temperature - return temperature difference, the relay conducts and the heating equipment starts working;


When the detected temperature (current temperature) is ≥ the set temperature, the relay will disconnect and the heating equipment will stop working;


For example: set the temperature to 30 ℃ and the return temperature to 5 ℃;


When the temperature is 20 ℃ ≤ 25 ℃ (30-5=25), the relay will start heating when it is engaged. When the temperature reaches 30 ℃ ≥ the set temperature of 30 ℃, the relay will disconnect and stop heating;

1.3 Refrigeration Mode Description


When the detected temperature (current temperature) is ≥ the set temperature+return temperature, the relay conducts and the refrigeration equipment starts working;


When the detected temperature (current temperature) is less than or equal to the set temperature, the relay will disconnect and the refrigeration equipment will stop working;


For example: set the temperature to 30 ℃ and the return temperature to 5 ℃;


When the temperature reaches 36 ℃ ≥ 35 ℃ (30+5=35), the relay will start to cool. When the temperature reaches 30 ℃ ≤ the set temperature of 30 ℃, the relay will disconnect and stop cooling;


1.4 Description of delayed start function


How long (in seconds) does it take to allow the next heating/cooling process after the end of one heating/cooling process;

1.5 Temperature correction function


If the system works for a long time, there may be deviations. By using this function to correct, the current temperature=measured temperature+calibration value;

1.6 High and low temperature alarm function


Buzzer on and off: After being turned on, the buzzer will sound when an alarm is triggered. After pressing the button, the buzzer will stop sounding;


High temperature alarm: After activating the high temperature alarm, if the current temperature is higher than the high temperature alarm temperature, the relay will disconnect;


Low temperature alarm: After activating the low temperature alarm, if the current temperature is lower than the low temperature alarm temperature, the relay will disconnect;


1.7 Emergency braking function (emergency stop function)


After activating the emergency stop, the relay will disconnect in any state; After the emergency stop is turned off, the relay returns to its normal state;

Can the product be disconnected from the network and run offline in 1.8 automatic mode


In automatic mode, when the parameters are set, the product can run offline without losing power.


2.1 Manual Mode Function Description


In manual mode, timing, delay, cycle, and jog can be set;

2.2 Power on state setting instructions


Power on status - on: After power on, the relay defaults to being engaged;


Power on state - off: After power on, the relay defaults to off;


Power on state - Maintain: Automatically restore relay state before power off after power on

2.3 Can the product be disconnected from the network and run offline in manual mode


In manual mode, the product cannot be disconnected and run offline.

2.4 Other Function Description in Manual Mode


Other functions are the same as in automatic mode

3. Sharing settings


Can be shared with others, enabling multiple people to share a device and control its functions.


4. Operation records


It can store all operation records in the background, including power on+timer+button+APP+heating and cooling mode, making it convenient to query the relay action status;


6. Cloud based recording and upload frequency


Temperature data can be stored in the background, and the frequency of log uploads can be set, with a maximum of 1 second per message (default of 5 minutes per message); You can freely query data for any time period, and retain data up to 15 days at most; In the later stage, cloud data export function can be added to facilitate the next step analysis of temperature data
