# AC: Air conditioner control

This module is the vehicle air conditioning control module. This module is provided in EdgerOS 2.0.0 and later, and apps need to have vehicle.cockpit permission to use this module.

User can use the following code to import the AC module.

var AC = require('vehicle/ac');

# Support

The following shows AC module APIs available for each permissions.

# AC Class

# new AC()

• Returns: {Object} AC object.

Create a AC object.

# AC Object

# ac.request(callback)

• callback {Function} Callback.
  • error {Error} Specify the error message when the request is failed.

Request for vehicle air conditioning operation. After the request is successful, the vehicle air conditioner information can be obtained and the air conditioner can be controlled.

# ac.release()

Release the current AC object, no operation is allowed after the object is released.

The object needs to be released as soon as possible when it is no longer used.

# ac.info(callback)

• callback {Function} Callback.
  • error {Error} Specify the error message when failed.
  • info {Object} Air conditioner information.

Get air conditioning information. The info object contains the following members:

The temperature string (lhTemp and rhTemp) information contains the following possible:

'LOW', '16.5', '17', '17.5', '18', '18.5', '19', '19.5', '20', '20.5', '21', '21.5', '22', '22.5', '23', '23.5', '24', '24.5', '25', '25.5', '26', '26.5', '27', '27.5', '28', '28.5', '29', '29.5', '30', '30.5', '31', '31.5', 'HIGH'

Blower mode: blowerModSt has the following types:

The info object may also contains the following members:

# Example

var AC = require('vehicle/ac');

var ac = new AC();

ac.request(error => {
  if (error == undefined) {
    ac.info((error, info) => {
      if (info) {
        console.log(info);
      }
    });
  }
});

# ac.temperature(temp, callback)

• temp {Object} Temperature object.
• callback {Function} Callback.
  • error {Error} Specify the error message when an error occurs.

Set the interior temperature. temperature object can contain the following members:

• lhTemp {String} Left front temperature.
• rhTemp {String} Right front temperature.

# Example

ac.temperature({
  lhTemp: '24.5', rhTemp: 'LOW'
}, error => {
  if (error) {
    console.error(error);
  }
});

# ac.blower(param, callback)

• param {Object} Blower parameter object.
• callback {Function} Callback.
  • error {Error} Specify the error message when an error occurs.

Set blower parameters:

• blowerModSt {Integer} Blower mode.
• blowerSpd {Integer} Blower speed. (0 - 10)

# Example

ac.blower({
  blowerModSt: 4, blowerSpd: 2
}, error => {
  if (error) {
    console.error(error);
  }
});

# ac.control(param, callback)

• param {Object} Control parameter object.
• callback {Function} Callback.
  • error {Error} Specify the error message when an error occurs.

Control air conditioner:

• airCondSt {Integer} 0: OFF 1: ON.
• auto {Boolean} Whether to automatically turn on and off the air conditioner according to the temperature.
• cycleThr {Integer} 0: Internal circulation 100: External circulation.

# Example

ac.control({
  airCondSt: 0, auto: true, cycleThr: 80
}, error => {
  if (error) {
    console.error(error);
  }
});

# AC Object Events

The ac object inherits from the EventEmitter class. The following events are thrown in some specific situations.

# info

When the state of the air conditioner changes, this event will be generated.

# Example

ac.on('info', info => {
  console.log(info);
});
