Digital thermostat W3230 with external sensor -50°C - +120°C, 12V

A simple digital thermostat with an output relay allows you to regulate the temperature in the range of -55°C ~ 120°C with a resolution of 0.1°C. For example, heating or cooling can be connected to one output. Heating and cooling will then maintain the set temperature on the thermostat. The thermostat includes a resistance temperature sensor in a waterproof stainless steel housing with IP68 protection. In the event of a power failure, the thermostat settings are saved. Power supply 12V DC.

Adjustable temperature: -50°C ~ 120°C (resolution 0.1°C)

Instructions for use:
A short press of the RESTART button turns the thermostat on, a long press turns it off. A short press of the SET button allows you to set the desired temperature using the up and down arrows after the display flashes. A long press of the SET button and then using the arrows allows you to set other functions of the thermostat:

P0: heating mode (H) or cooling mode (C)
P1: hysteresis setting 0.1 to 30°C
P2: setting the upper maximum temperature limit
P3: setting the lower maximum temperature limit
P4: temperature correction compared to the temperature sensor –10 to 10°C
P5: time delay 0 to 10 minutes
P6: Signaling of reaching the maximum temperature –50 to 120°C (factory disabled)
P7: Keyboard lock
P8: Factory reset

The product is not a stand-alone functional unit and requires professional assembly.
