Hello,
I bought this programmable thermostat W1209 with display lcd. It is very cheap and easy to program, you can determine maximum temperature, or minimum temperature, etc.

But I have a problem: when I disconnect the power, the programming is erased. And when I connect it, I have to reprogram it again. This is normal?
I do not know what company makes it, to consult them. Does anyone use this thermostat?
