Thermostat Thermoregulator Sensor Microcomputer Temperature Humidity Controller for Incubator Cooling Heating Fridge Fish Pet Reptile Aquarium Fish Tank Incubation

- When the thermostat is working normally, press and hold the power button for more than 3 seconds to turn off the thermostat. When the thermostat is off, press and hold the power button for more than 3 seconds to open the thermostat.

- When the thermostat is working normally, the digital tube displays the current temperature measurement value, and performs automatic recognition conversion of the cooling heating operation mode.

- When the measured temperature ≥ temperature set value + temperature difference set value, enter the cooling state, the Cool indicator light is on, the cooling relay normally open contact is closed; the Cool indicator flashes, indicating that the cooling device is in the press delay protection state; when measuring the temperature ≤ temperature set value, the Cool indicator is off, and the normally open contact of the refrigeration relay is disconnected.

- When the measured temperature ≤ temperature set value - temperature difference set value enters the heating state, the Heat indicator light is on, the heating relay normally open contact is closed; when the measured temperature ≥ temperature set value, the Heat indicator is off, the heating relay normally open contact disconnect.
