.

2.

Press and hold the

+

6.

Repeat steps 3 through 5 to change more parameters.

7.

10 seconds after the last display or setting, all changes are saved and the
thermostat returns to Protection mode.

Reload the factory setting of the control parameters as follows:

1.

Set the thermostat to Protection mode

.

2.

Press the

+

and

buttons simultaneously for 3 seconds. Release them and,
