Smart Digital Thermostat - Temperature Regulator Module - with W1401 Sensor

The red LED on the left (START INDICATOR) lights up when the relay is on. The green diode (STOP INDICATOR) is on when the relay is turned off. The display in the center shows the current temperature read from the NTC sensor. The left-hand display shows the set start temperature, the right-hand display shows the set end temperature.

The thermostat saves preset settings when disconnected form power.

Functions

Cooling function - We set the initial temperature higher than the final temperature. If the temperature read by the sensor is greater than or equal to the starting temperature, the relay is energized and the cooling device operates. If the temperature is lower than or equal to the STOP temperature, the relay will disconnect and the cooling device will stop working until the temperature reaches the START temperature again.

Heating function - The start temperature must be lower than the end temperature - then the heating device switches on. If the measured temperature reaches the temperature equal to or higher than the set temperature, the heating device will turn off.
