W1209 12V DC Digital Cooling/Heating Thermostat Temp Control -50-110 °c Temperature Controller 10A Relay with Waterproof Sensor Probe
- Determine the working mode: Press and hold SET for about 5 seconds to display P0. Press SET again to modify the value of P0. H is the heating mode and C is the cooling mode.
- Automatic power set memory (MCU built-in EEPROM memory unit). Control accuracy of 0.1 degrees Celsius. Have been tested for stability, consistency and reliability.
- lectronic digital thermostat with a 3-digit LED display, extremely bright. Operation both in heating and cooling to easily control equipment and devices.
- The NTC probe is waterproof and allows to control the temperature even of fluids, allowing the controlled heated or cooling
- 100% complete machine patch, wave soldering, stable performance, good consistency.
Product Description
Instructions for use:
Connect the power supply and equipment, the measuring temperature is displayed, press the “SET” button, press ” + or – ” to set the desired temperature (long press ” + or – ” to quickly increase or decrease), press the “SET” to confirm the setting and return, controller automatically performs the relay ON/OFF.
LED Indicator: LED off indicates the relay off; Lighting, indicates the relay is closed.
Digital LED Tubes: “LL” indicates sensor open, “HH” indicates overrange, the relay will be forcibly disconnected; “—” indicates high temperature alarm
Long press the “SET” button to enter the main menu settings,
press ” + or – ” to switching between P0-P6,
then long press “SET” or 10 seconds without keystrokes to confirm the setting and return.
the thermostat output is 10A relay, meet a variety of high-power loads.
