-50°C to 110°C Thermostat - 12V - with VKS-W1209 Temperature Controller

Electronic thermostat powered by 12V, works in the temperature range from -50 ° C to + 110 ° C. It has temperature regulation which allows you to control connected external devices. It can be used to turn on and off devices in your own projects, aquariums, swimming pools, cold stores, refrigerators, etc. The waterproof sensor has a cable about 30 cm long.
Setting the activation temperature: press the SET button, when the displayed set temperature starts flashing, use up and down buttons to adjust the settings.

Programming mode:
Entering the programming mode is started by pressing the SET button (about 3 seconds). The settings are changed with the + and - buttons, successively we go from P0, P1 to P6 and return to P0 again. The parameters are saved automatically and after 3 seconds the module automatically exits the programming mode into the standard temperature display mode.

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 - thermometer calibration in the range -7 ° C to 7 ° C (set when the temperature indications 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

Pinout:

VCC - positive power supply
GND - negative power supply
K0, K1 - output relay contacts
