Thermostat 12V W2 -50°C to 110°C - Red-Blue - with Temperature Controller & Relay

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. The display shows the actual and set temperature. 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. Programming Mode: Entering the settings takes place by holding the SET button for about 3 seconds. The flashing upper character of the display informs that we are in the programming mode. By pressing the upper or lower button, we move through the following programming modes, to enter each of them we press both buttons at the same time. The same settings are saved by clicking both buttons at the same time: P0 H / C Operation mode heating "H" cooling "C" (default C) P1 is a hysteresis, i.e. an acceptable temperature range in which the controller does not take any action P2 upper limit of the allowed temperature, possible to be set from the panel using the up and down buttons; P3 lower limit of the allowed temperature, possible to be set from the panel using the up and down buttons; P4 Temperature sensor correction (calibration) (-15 to +15) P5 Adjustment of reaction time to change of the set temperature. Adjustable within the range from 0 to 10 minutes P6 Setting the alarm of exceeding the temperature - the buzzer is activated and the signs "HHH" are displayed: ON / OFF, by default, OFF is changed to ON and confirmed with two buttons, and then set the desired alarm temperature. P7 ° C / F display setting - also when holding down the lower button P8 Restoring factory settings To enter the selected mode, click both buttons at the same time. The regulator has an alarm of a damaged circuit of the temperature sensor, which means that the meter has an additional protection. The value of the regulated temperature can be changed by pressing the SET button for about 2 seconds, when the display starts flashing, then use the buttons to change the temperature. After a few seconds of inactivity, the regulator returns to the standby mode by itself. Technical data measuring range: -50°C to 110°C two LED displays: the upper one in red (sensor temperature), the lower one in blue (temperature setting). built-in buzzer ambient temperature: -10°C to 60°C measurement accuracy +/- 1.0°C power supply: 12V DC dimensions: 48 x 29 x 32 mm housing color: black LED display: blue / red sensor cable length (waterproof): ~ 30cm
