HT1209 Programmable Digital Thermostat
This HT1209 is a low cost yet highly functional thermostat controller. With this module you
can intelligently control power to most types of electrical devices based on the temperature
sensed by the included high accuracy NTC temperature sensor probe. 3 tactile switches allow
for setting of various parameters including on & off trigger temperatures. The on board relay
can switch up to a maximum of 240VAC at 5A or 14V DC at 10A. The actual temperature is
displayed in degrees Centigrade with 3-digit 7-segment display. The relay On/Off state
indicates by on board LED indicator.

Page 3: Parameter Setting
Operating Instructions: Connect the power supply and after powered up, the actual measured temperature is displayed on the module. After pressing the "SET" button, press “ + “ or “ - " to set the desired control temperature (long press " + “ or “ - " to fast increase or decrease). Press "SET" again to confirm the setting and return. The controller module with automatically monitor the temperature and performs the relay ON/OFF according to the temperature set. - Page 4 approximately 5 seconds the thermostat will exit the parameter options and will return back to the default temperature display. Description Range Default Value Code Heating/Cooling hysteresis 0.1-15 Upper Limit Lower Limit Correction -7.0 ~ 7.0 Delay Start Time 0-10 mins High Temperature Alarm 0-110 P0: Cooling or heating parameter:...
- Page 5 Application Examples: Connect the circuit as shown below: In this application examples, the fan will be switched ‘On’ when the temperature reached the limit set by the user. The fan will be switched ‘Off’ when the temperature cool down to the normal temperature. In this case, the fan is supply from same power supply as module, limited to maximum of 12V.
