A wireless controller () is configured to send commands to a mini-split HVAC unit () that thermostatically controls a temperature in a space () using the temperature sensed and a programmable set point. The wireless controller () may include an infrared (IR) transmitter (), a temperature sensor (), a user interface (), a non-volatile memory (), and a controller (). The wireless controller () may store an IR database in the non-volatile memory () for each of a wide variety of mini-split HVAC unit (). The wireless controller () may then allow a user to select a particular mini-split HVAC unit (), and from the selection may identify a corresponding IR protocol in the IR database. During subsequent use, the wireless controller () may use the corresponding IR protocol during subsequent communication with the mini-split HVAC unit ().

A wireless controller to set a programmable setpoint of a remote HVAC unit that thermostatically controls a temperature in a space using the temperature sensed and a programmable setpoint. The wireless controller may include a transmitter, a memory, a temperature sensor, and a controller. The wireless controller may transmit commands to set the programmable setpoint of the remote HVAC unit, wait until the temperature sensed by the temperature sensor of the wireless controller stabilizes, determine a difference between the desired setpoint temperature and the stabilized temperature, and if the offset temperature is greater than or equal to a threshold offset, determine an updated control setpoint temperature and transmit commands to set the programmable setpoint of the remote HVAC unit to an updated control setpoint temperature.

Method and system for controlling a mini-split HVAC unit from a remote location

In some examples, a system controls a set of heating, ventilation, and air conditioning (HVAC) components in order to regulate one or more parameters of a building. The system includes an HVAC controller device including a dial and a touch screen display. Additionally, the system includes an external server configured to communicate with the HVAC controller via a communication link. The external server is configured to receive data which indicates a set of information from one or more devices. Additionally, the external server is configured to generate, based on the set of information and a set of screen templates stored in a memory of the external server, a screen for display by the touch screen display without updating firmware of the HVAC controller device, and output, to the HVAC controller device, the screen for display by the touch screen display.
