The day of the week and the clock of your VESTA THERMOSTAT are set automatically if you connect the thermostat to WiFi through the app, but if this fails you can always adjust it manually.
Hold down the button M for 3 seconds and adjust the time and date with the arrows.
Each time you press the M button you will change to the following setting:
| 01 |
Minute |
| 02 | Hour |
| 03 | Day of the week |
