The three control buttons are logically located and are self-evident.
The programming of heating times is quickly understood and programmed just as quickly.
The manual control of the temperature is also very compatible.
VERY IMPORTANT: The "Home Xpert by Honeywell HR20 style Rondostat programmable radiator controller" makes exactly what he's told. He is reliable and the switching times starting just seconds. Here you can really rely on the product.
I highly recommend it. It saves time, and especially one forgets no longer issue the heater.
