Intelligent dual temperature control relay instructions
Tips: Set the temperature when the buyer must ensure that the upper limit temperature is greater than the lower limit temperature, the system will work properly.
Circuit connection: Connect the power supply with reference to the circuit diagram and load, the temperature sensor is missing or damaged digital tube will show "- - -", before using buyer must check the temperature sensor is installed.
The temperature output 10A relay, to meet a variety of high-power load, make sure that the line is correct.
LEDs, LED status descriptions:
LED: Off indicates the relay off, ON means the relay is closed
Digital: Display "- - -", 1, check the temperature sensor 2 is missing or damaged, heating mode, high temperature protection 3, cryogenic cooling mode protection. In protected mode relay automatically disconnected.
Use keys: temperature control panel has three buttons, button + button - SET button
Button +: Achieving Rapid accumulation value
Key: - fast diminishing value
SET key SET: Temperature set temperature and operating mode interface query interface parameter setting interface
During the SET press SET press according to different times, the corresponding digital temperature limit will be blinking, you can set the upper and lower temperature through the key addition and subtraction. After setting 8s automatically save data or short press three times data can be saved.
SET Press to enter the actual temperature and the operating mode query interface, digital (on) the actual measured temperature. Digital (lower) showing the operation mode. L represents the lower limit temperature below the set temperature, H is the upper limit temperature is higher than the temperature setting, OFF indicates when the temperature is between the upper and lower limits, the relay is in the off state.
Mode setting: Setting the temperature 1: temperature upper limit set temperature 2: lower limit temperature
Example applications: now the upper limit temperature to 40.0 ℃, the minimum temperature is set to 20.0 ℃. At different temperature ranges relay operate as follows:
When the actual temperature> 40 ℃, the relay 1 is closed, the relay 2 release;
When the actual temperature of 20 ℃ ≤ ≤40 ℃ release relay 1, relay 2 release;
When the actual temperature <20 ℃, the relay 2 is closed, the relay 1 release.
Parameter settings: the need for the user parameter settings must first hold the SET button and then give the thermostat power, to enter the parameter setting interface. There are three sets of parameters P0-P2 can be used for user settings.
Parameter setting item
Function Description Setting range Factory setting
P0 temperature correction -10 ℃ ~ + 10 ℃ 0
P1 limit relay time 0 ~ 999s OFF
P2 lower limit relay time 0 ~ 999s OFF
friendly reminder:
P1 = OFF: indicates the actual temperature exceeds the upper limit temperature, corresponding relay will remain energized (long attracted state).
P1 = 1 ~ 999: indicates the actual temperature exceeds the upper limit temperature, corresponding relay will energize long, then stop (Jog attracted state).
P2 = OFF: indicates the actual temperature is below the lower limit temperature, corresponding relay will remain energized (long attracted state).
P2 = 1 ~ 999: indicates the actual temperature is below the lower limit temperature, corresponding relay will energize long, then stop (Jog attracted state).
