Essential Info

The INSTEON Wireless Thermostat is powered by (and comes with) two AA batteries. However, if you prefer constant power, without the worry of your batteries failing, this plug in 6V DC Power Supply is the perfect alternative. When the power supply is connected, the Wireless Thermostat stays awake and is instantly available for polling status and controlling other devices. The Power Supply comes with exposed pigtail wire leads that connect directly into the INSTEON Wireless Thermostat. For added convenience, a cutout for the power supply wire on the Thermostat case and wire termination connections within the Thermostat are already in place.

  • This power supply is required if the LCD backlight on the INSTEON Wireless Thermostat is set to continuous On
  • If operating the INSTEON Wireless Thermostat on battery power, status and control commands are sent once per minute if the temperature or humidity changes
  • What's Included

  • 1x - 6V DC Power Supply
