The W1209 is an incredibly 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. Although this module has an embedded microcontroller, no programming knowledge is required. Three tactile switches allow for configuring various parameters including on & off trigger temperatures. The on board relay can switch up to a maximum of 240VAC at 5A or 12V DC at 10A. The current temperature is displayed in degrees centigrade via its 3 digit seven sigment display and the current relay state by an on board LED.
Note: This module uses on-board non-volatile memory to store changes made to its settings, therefore any changes made will be saved even if power is removed from the module.
Parameter 0 can be set to either Hot or Cold Control setting. The relay module is based on a microcontroller (MCU) and has 7 user-configurable parameters accessible using 3 push buttons.
