Digital Thermostat W1219 - Adjustable -50C + 110C - Module - Dual Display
W1219 thermostat with a double digital display (the upper display shows current temperature, the lower display shows the set temperature). A not very complicated module of an integrated thermostat thanks to which we can control load up to 2300W.
The module has a detachable waterproof NTC thermistor that measures the temperature.
The process of setting the temperature is very simple, just press the "SET" button - then the display starts flashing and then, using + and - buttons set the desired temperature value.
The module has a heating and cooling function: H / C, depending on the selected mode, eg H, the relay will be turned on below the set value until it is reached + set or not hysteresis.
On the other hand, the C function, i.e. cooling, the relay will turn on above the set temperature and will work until it is reached.
The module remembers the set value even after disconnecting from power supply.

NTC10k sensor on a 30cm cable
Measurement frequency 2 / s
MENU - to enter programming mode, hold the SET button for about 4-5 seconds.
setting programming mode P0 - P6 is selected using + and - buttons
enter the selected mode by pressing the SET button
confirmation of the selected value by pressing the SET button
Programming modes P0 - P6
P0 - C / H selection, cooling or heating
P1 - hysteresis operating range, selectable from 0.5 to 15 ° C
P2 - upper temperature limit (default 110 * C), range -45 ° C to 110 ° C
P3 - lower temperature limit (default -50 * C), range -50 ° C to 110 ° C
P4 - calibration of the thermometer in the range -7 ° C to 7 ° C (set when the temperature readings are incorrect)
P5 - relay activation delay time in the range from 0min to 10min
P6 - too high temperature alarm, adjustable from 0 to 110 ° C
simultaneous activation of the + and - buttons at the moment of switching on the supply voltage causes a reset to the factory settings
