Provided are a control method and device for a wall-mounted indoor air-conditioning unit, and the wall-mounted indoor air-conditioning unit. The control method for the wall-mounted indoor air-conditioning unit comprises: receiving a trigger signal of starting a heating mode of the wall-mounted indoor air-conditioning unit, and acquiring a set temperature of the wall-mounted indoor air-conditioning unit; measuring an ambient temperature at a diagonal position of the wall-mounted indoor air-conditioning unit and the temperature of a heat exchanger of the wall-mounted indoor air-conditioning unit; determining whether the ambient temperature is smaller than a difference between the set temperature and a preset value or not, and enabling the temperature of the heat exchanger to be greater than or equal to a preset heat protection temperature; and if yes, adjusting the opening degree of an expansion valve of the wall-mounted indoor air-conditioning unit to cool the heat exchanger of the wall-mounted indoor air-conditioning unit. Under the premise of uniform distribution of indoor ambient temperature, the heat protection is started according to actual situations, so that the wall-mounted indoor air-conditioning unit is prevented from easily and frequently starting heat protection, and the heating effect of the wall-mounted indoor air-conditioning unit is guaranteed.
