When the thermostat works normally, short press the 'S' key, the set temperature value flashes, use '∧' or '∨' long press or short press to modify the set temperature parameter; press and hold the 'S' key for more than 3 seconds to enter the modified parameter In the mode, the nixie tube displays the code 'HC' of the first menu item. Press the '∧' or '∨' key to increase or decrease the code of the menu item. Press the 'S' key to display the parameter settings of the current menu. Short press '∧ 'or '∨' key can increase or decrease and display the parameter setting value of the current menu.
Press and hold the '∧' key to restore the parameters to the factory settings.
When the thermostat is working normally, press and hold the power key for more than 3 seconds to turn off the thermostat. When the thermostat is off, short press the power key to turn on the thermostat.
When the thermostat works normally, the digital tube displays the current temperature measurement value.
First set the temperature control working state, heating or cooling.
Heating mode: When the measured temperature ≤ temperature set value-temperature difference set value, the Work indicator lights, the relay normally open contact closes; the Work indicator flashes, indicating that the press is in the delayed protection state; when the measured temperature ≥ temperature setting Value, the Work indicator is off, and the normally open contact of the relay is disconnected.
Refrigeration mode: When the measured temperature ≥ temperature set value + temperature difference set value, the Work indicator lights, the relay normally open contact is closed; the Work indicator flashes, indicating that the press is in the delayed protection state; when the measured temperature ≤ temperature setting Value, the Work indicator is off, and the normally open contact of the relay is disconnected.
Work indicator: On: working, flashing: delay
Set indicator: On: parameter setting
Repair system data:
After the thermostat is powered on, first check whether the parameter settings are correct. If an error is detected, “Er” is displayed. At this time, press any key to restore the default parameter settings and work normally. It is recommended to reset the parameters at this time.
System code, reason and action:
Sensor failure alarm: When the temperature probe circuit has a short circuit or open circuit failure, the thermostat activates the probe failure alarm mode and closes all execution states. The digital tube displays "LLL". After the failure is removed, press any key to return to normal working mode.
Over temperature limit alarm: When the temperature measurement exceeds the temperature measurement range, the thermostat starts the over temperature limit fault alarm mode, closes all execution states, the digital tube displays "HHH", when the temperature returns to the normal measurement range, press any key, Return to normal working mode.
Strictly distinguish the sensor lead, power cord and output relay interface, can not be connected wrong, the relay must not be overloaded
All wiring changes must be made with the power disconnected.
This thermostat is forbidden to be used in water or excessively humid environment, and is prohibited to be used in high temperature, strong electromagnetic interference and strong corrosive environment.
The power supply voltage should be consistent with the voltage marked by the thermostat, and ensure the stability of the power supply voltage
To avoid possible interference, it is recommended that the sensor leads be kept at an appropriate distance from the power line.
