A wireless controller () is configured to send commands to a mini-split HVAC unit () that thermostatically controls the temperature in a space () using the temperature sensed and a programmable set point. The wireless controller () may include an IR transmitter (), a temperature sensor (), a user interface (), and a controller (). The controller () may receive a selection of a shortcut button definition option, present menu screens that allow a user to select functions for assignment to a shortcut button, receive selections of functions for assignment to the shortcut button, assign the selected functions to the shortcut button, and when the shortcut button is subsequently activated, transmit commands to the mini-split HVAC unit () that carries out the selected functions assigned to the shortcut button.

Wireless controller for an HVAC system with a programmable shortcut button

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 ().

Universal wireless HVAC controller with an internally stored infrared (IR) database

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.
