Flawless Thermostat. It's worth 100% of its money. Touch screen display.
Easy connection and setup with the Smart Rm and Smart Life apps.
I preferred the Smart Rm.
Countless functions through the app and scenario settings (e.g. Saturday morning, open at 17 degrees, close at 20 degrees).
It has a weekly programming feature for all days and desired temperatures.
My new thermostat replaced an old one that broke and I never knew when the burner would turn off. I had to manually shut it down in case the temperature rose too high in the house, resulting in discomfort from the heat.
So, a few words about my new thermostat. It must be connected with 3 cables that come from the wall (spiral-internal structured wiring). In case you only have 2 cables (very old installations), you bridge it. In new installations, usually 4 cables come from the wall - spiral. It also comes with an external sensor (optional placement).
On the very bright and readable screen (brightness can be adjusted, e.g. at night, to avoid eye strain), the following are indicated from top left to right: time, day, date, Wi-Fi connection status, cloud connection status, locked padlock symbol (for additional safety, e.g. to prevent children from tampering with it), outdoor ambient temperature below the green line, weather on the left and air quality on the right of the vertical white bar, as well as the presence of airborne particles in the atmosphere (e.g. haze, exhaust fumes, etc.) below. On the right, there is a symbol with a hand (manual or automatic mode). The central digital dial displays the room temperature, and the blue letters indicate the desired temperature inside the house. Below, it opens and closes with the familiar symbol. The desired temperature can be adjusted with the arrows, and the thermostat settings can be adjusted with the gear icon.
To connect with the app, after downloading it, press the gear icon on the thermostat and, after turning on Bluetooth on our mobile phone, find the Wi-Fi icon on our thermostat and press it to search. Add the thermostat from our app, and if it asks for a code, enter 123456. The code is necessary to be entered every time we make manual changes on the thermostat.
It works for any type of oil, natural gas, or pellet burner. It also supports underfloor heating. There are numerous settings in its menu and calibration capability. What exactly does calibration mean? If, for example, the temperature indicated in white letters is lower or higher than that of a highly accurate thermometer, you can adjust it so that it always shows the correct external temperature. (In my case, I calibrated the thermostat based on a digital thermometer from Tp Link (model Tapo T315) as well as a simple mercury one. I have attached a photo next to the thermostat.)
The final result - the indication on the thermostat has no deviation of even 0.1 degrees. It is exactly what the thermostat, the digital thermometer, and the simple mercury thermometer show.
Attention: If your wall is not recessed, e.g. plasterboard, and you don't want to dig into the wall, you need to get the external plastic box that fits all thermostats.
These (few things) Sorry if I tired you with the text, just to clarify any questions for anyone interested. I have been very satisfied
