Factory Reset
The thermostat has a factory reset function. This will reset
all settings back to their factory default.
To perform a factory reset, follow these steps:
Turn off the thermostat by pressing and holding the off
button. Press and hold the bottom left corner of the LCD for
10 seconds. You will see all the icons appear for 2 seconds
and then disappear. You now need to power down the
thermostat for 5 seconds and then power on again.
