Product Description

This fantastic countdown timer from Secure can be used as a standalone countdown timer (with the options for 30, 60 or 120 minutes controllable from the front-switch) or you can set any countdown time you like via your Z-Wave smart home controller (in 1 minute increments, up to 24 hours).

With the ability to switch up to 3kW of load, this is an ideal device to add to storage heaters, immersion heaters, towel rails and other devices which you want to turn on for a limited period of time (perhaps the tumble dryer?).

  • Z-Wave controlled 3 kW countdown time switch
  • Can be controlled by any Z-Wave controller (e.g. Fibaro, Vera, Zipato)
  • 868.4 MHz radio frequency - for use in 47 member countries of CEPT (including whole of EU), plus China, Singapore, South Africa & UAE
  • Local manual control can set times of 30, 60 or 120 minutes
  • Z-Wave control can set countdown times between 1 minute and 24 hours, in 1 minute increments

You can also use an optional temperature probe - the SEC_SES001NTC - to provide temperature reporting to your Z-Wave controller from the switch, making it even more useful for controlling heating or cooling devices.
