    Simple and Easy to Use

    I bought this thermostat to use with one of Thermisia’s UV Printed heaters that doesn’t have a built-in thermostat. I prefer a simple remote setup rather than Wi-Fi apps and smart home integrations, so this was exactly what I was looking for. It’s easy to turn the heater on and off, the timer function is handy, and the remote works well. Simple, reliable and does the job.
