    Digital Thermostat Temperature Control Switch Sensor Module With Acrylic Enclosure Case
    The W1209 is a low cost yet highly functional thermostat controller with a clear acrylic plastic enclosure. This module intelligently controls power to most types of electrical devices based on the temperature sensed by the included high accuracy NTC remote temperature sensor.
    The cooler, heater or fan is connected to a power supply through the relay contacts K0 and K1, and the temperature on/off setpoints are programmed into the W1209 using the onboard Set, Increase and Decrease buttons and display. The relay contacts are then open and closed, acting as a power switch for the cooler/heater, based on the temperature measured
    by the NTC temperature sensor (included with the module) and the setpoints programmed into the W1209 controller.
    Although this module has an embedded microcontroller, no programming knowledge is required. 3 tactile switches allow for configuring various parameters including on & off trigger temperatures. The on-board relay can switch up to a maximum of 125V AC at 10A or 14V DC at 20A. The current temperature is displayed in degrees Centigrade via its 3 digit seven segment display and the current relay state by an on board LED.
    Specifications:
    Temperature Control Range: -50 C to +110 C (-58 F to +230 F)
    Resolution at -9.9 to 99.9: 0.1 C
    Resolution at all other temperatures: 1 C
    Measurement Accuracy: 0.1 C
    Control Accuracy: 0.1 C
    Refresh Rate: 0.5 Seconds
    Input Power (DC): 6V to 12V @ 65mA maximum (Provides power for the module, not the load)
    NOTE: The maximum input support voltage should not exceed 12V. In applications such as an automobile or RV where the battery voltage can exceed 12V, a regulator circuit such as a 1N5349A zener diode and a series resistor in the range of 20 Ohm 1W should be used to limit the voltage to 12V. Alternately, a
    12V to 9V buck voltage converter
    with the input to the converter connected to the battery and the output to the W1209 will provide a stable 9V DC supply for the W1209.
    Measuring Input: NTC (10K 0.5%)
    Waterproof Sensor: 0.5M cable
    Probe tip dimensions: 20mm long x 4mm diameter
    Output: 1 Channel Relay Output, Capacity: 10A @ 125VAC or 20A @ 14VDC
    Includes a Clear Acrylic Case (Box) with mounting screws (assembly required)
    Power Consumption:
    Static Current: <=35mA
    Operating Current: <=65mA
    Environmental Requirements:
    Temperature: -10 ~ 60 C
    Humidity: 20-85%
    Dimensions:
    W1209 Board
    (LxWxH)
    : 48mm x 40mm x 14mm (1.9" x 1.6" x 0.6")
    Case (Assembled L x W x H): 59mm x 51mm x 18mm (2.3" x 2.0" x 0.71")
    The display defaults to showing the measured temperature.
    Short press the "SET" button and then press "+" and "-" buttons to raise or lower the temperature setpoint.
    Long press the “SET” button to activate the menu in order to change the P0 through P6 parameters listed in the Settings Chart below.
    The setpoint and all parameter settings are stored in nonvolatile memory and will be retained if power to the controller is turned off.
    Settings Chart:
    Code: Description / Range / Default Value
    P0: Set Heating or Cooling Mode / C/H / C
    P1: Hysteresis Set / 0.1C - 15C / 2C
    P2: Upper Temperature Limit / 110C / 110C
    P3: Lower Temperature Limit / -50C / -50C
    P4: Temperature Calibration / -7.0C ~ 7.0C / 0C
    P5: Delay Start Time / 0-10 mins / 0 mins
    P6/P7: High Temperature Alarm / 0C - 110C / OFF
    P8: Factory Reset (Not included in all firmware versions. Can also be reset by pressing and holding the + and - buttons for 5 seconds.)
