This cooling energy saving parameter is ashing behind top-left colon. The default value is 23°C. This lowest target

cooling temperature can be adjusted by . After setting, press key to conrm and exit.

(2) Under heating mode 16°C, keep pressing key for 5 seconds to set energy saving parameter in heating

mode. This heating energy saving parameter is ashing behind top-right colon. The default value is 26°C. This

highest target heating temperature can be adjusted by . After setting, press key to conrm and exit.

(3) Energy saving parameter will be valid after energy saving icon displays.
