In order to change a temperature setpoint on a touch panel, use plus (+) and minus (–) buttons:
- 1 press of a plus button enters the temperature setpoint editing mode;
- press a plus button (single press or long press) to increment the temperature setpoint by a step value set in the SETPOINT_STEP register/object (decimal address: 1507);
- press a minus button (single press or long press) to decrement the temperature setpoint by a step value set in the SETPOINT_STEP register/object (decimal address: 1507);
- stop pressing buttons when the required value is reached; the display will end the editing mode after a time set in the EXIT_EDIT_TIME register/object (decimal address: 223).
An unavailable action is signalized by a double beep.
