The electronic thermostat W1209 measures and automatically maintains the temperature of the working environment within the specified limits, by turning on or off external heating (heating element, oven, heater) or cooling (freezer, fan, peltier module) units.
The actuator of the thermostat is a two-position relay for 1 channel. The relay has two positions: default closed contacts and default open contacts.

The sensor is a 10kOm NTC thermistor in a waterproof well. The length of the sensor with a wire is 30cm.
There is a start delay, temperature calibration, hysteresis setting.

Main characteristics:

  • Supply voltage: DC 12V
  • Current consumption: ≤35mA in measurement mode, ≤65mA in relay closing mode
  • Measured temperature range: -45°C ~ 110°C
  • Temperature measurement accuracy:
    • in the range of -9.9°C to 99.9°C: 0.1 °C
    • other temperature ranges: 1°C
  • Hysteresis Accuracy: 0.1°C
  • Measuring input: NTC 10kOm
  • Waterproof sensor 30cm
  • Display type: blue seven segment LED display
  • Refresh period: 0.5s
  • Relay output: 1 channel 10A 250V
  • Dimensions: 48 x 40 x 18mm
Connection, indication and setting of the thermostat.
 
Connection and temperature setting:
  • Connect power to terminals+12V and GND. The display will show the current temperature of the sensor.
  • Briefly press the "SET" button. The display will blink. You are in the mode of setting the preset temperature for switching off (switching on) the relay.
  • Use the "+" or "-" buttons to set the required temperature.
  • Briefly press the "SET" button to save the setting.
If "LLL" appears on the display when switching on or in operating mode, check the sensor connection, the cable may be broken.

Connection diagram:


Advanced thermostat setting:
  • Connect the power supply.
  • Press the "SET" button and hold it for at least 5 seconds. The display will show one of the symbols "P0" - "P6". You are in parameter setting mode.
  • Use the "+" or "-" buttons to select one of the parameters P0-P6.
  • Briefly press the "SET" button. You are in parameter editing mode.
  • Use the "+" or "-" buttons to set the parameter.
  • Briefly press the "SET" button. You have exited parameter edit mode. The parameter is saved.
  • To exit the parameter setting mode, press the "SET" button and hold it for at least 5 seconds.
  • The display will show the current temperature at the sensor.
Parameter table:
 
Parameter Description Range
customization
Factory
customization
P0 Heating/cooling C/H FROM
P1 Hysteresis setting 0,1-15 °C 2 °C
P2 Maximum set point temperature -45..+110 °C 110 °C
P3 Minimum set point temperature -45..+110 °C -45 °C
P4 Temperature correction -7,0..+7,0 °C 0
P5 Delay on time 0-10 minutes 0
P6 Over temperature alarm 0-110 °C VC.



To reset the parameters to the factory settings, in the parameter setting mode, press and hold for at least 10 seconds. buttons "+" and "-" at the same time.

P0 - sets the operating mode for cooling or heating ("C" or "H").
P1 - sets the hysteresis parameter. (The difference between the temperature at which the thermostat turns on the load and the temperature at which it turns it off again is called hysteresis. Without this hysteresis, the thermostat would turn the load on and off almost every second.)
P4 - sets the temperature correction. (This parameter is used when the sensor has a long cable and the extra cable length affects the true value of the read temperature.) The sensor can be calibrated, for example, with a boiling point of water of 100°C.
P5 - sets the device start delay in the range from 0 to 10 minutes.
P6 - sets the high temperature alarm (relay off and "---" indication when the temperature reaches the value set in this parameter).
