1.1 Function description of automatic mode
1) First select heating mode/cooling mode.
2) Set the temperature and hysteresis difference, if you need to delay start, set the time of delay start.
3) If you need to set high and low temperature alarms, set the high and low temperature alarm thresholds yourself
1.2 Description of heating mode
When the detected temperature (current temperature) ≤ set temperature - hysteresis temperature, the relay is turned on, and the heating equipment starts to work.
When the detected temperature (current temperature) ≥ the set temperature, the relay is disconnected, and the heating device stops working.
Example: Set the temperature to 30°C and the return temperature to 5°C;
When the temperature is 20°C≤25°C (30-5 = 25), the relay pulls in and starts to heat, and when the temperature reaches 30°C ≥ the set temperature of 30°C, the relay turns off and stops heating.
1.3 Description of cooling mode
When the detected temperature (current temperature) ≥ set temperature + hysteresis temperature, the relay is turned on, and the refrigeration equipment starts to work.
When the detected temperature (current temperature) ≤ the set temperature, the relay is disconnected, and the refrigeration equipment stops working.
Example: Set the temperature to 30°C and the return temperature to 5°C;
When the temperature is 36°C ≥ 35°C (30+5 = 35), the relay pulls in to start cooling, and when the temperature reaches 30°C ≤ the set temperature 30°C, the relay turns off and stops cooling.
1.4 Description of delayed start function
After a heating/cooling process is over, how long to delay (unit: seconds) to allow the next heating/cooling.
1.5 Temperature correction function
If the system works for a long time, there may be deviations, which can be corrected by this function, the current temperature = measured temperature + calibration value.
1.6 High and low temperature alarm function
Buzzer on and off: After it is turned on, the buzzer will sound after the alarm, and when the button is pressed, the buzzer will stop sounding.
High temperature alarm: After the high temperature alarm is turned on, the relay is disconnected when the current temperature is higher than the high temperature alarm temperature.
Low temperature alarm: After the low temperature alarm is turned on, the relay is disconnected when the current temperature is lower than the low temperature alarm temperature.
1.7 Emergency braking function (emergency stop function)
After the emergency stop is turned on, the relay will be disconnected no matter what state it is in; after the emergency stop is turned off, the relay returns to the normal state.
1.8 Frequently asked question
Can the product be disconnected from the network and run offline in automatic mode?
In the automatic mode, when the parameters are set, the product can be disconnected from the network and run offline, and the parameters will not be lost when the power is turned off.
1.9 LAN data export function
The local area network will upload a piece of temperature data in 1 second. After clicking "Export", it will be automatically exported to EXCEL for analysis of the temperature data.
