1. A heating, ventilation and air conditioning (HVAC) control system comprising:
a smart base which is fixedly attached to a building whose HVAC unit is to be controlled, the smart base being directly connected to the HVAC unit to be controlled; and
a hub which is removably dockable to the smart base; wherein:
the smart base comprises:
a smart base user interface for controlling a limited set of HVAC parameters; and
a wireless communication module for communicating with the hub over a low power wireless network;
the hub comprises:
a hub user interface for controlling a comprehensive set of HVAC parameters; and
a wireless communication module for communicating with the smart base over the low power wireless network; and wherein
the hub and the smart base are configured to enable the hub user interface to control the comprehensive set of HVAC parameters if at least one of:
the hub is docked to the smart base; and
the hub is undocked from the smart base and the hub is within communication range of the smart base over the low power wireless network; and wherein if the hub is unable to communicate with the smart base over the low power wireless network the smart base controls the HVAC system dependent upon the smart base user interface and last active control settings stored in the smart base prior to losing communication connection with the hub.
