a user interface including a display;
a memory;
a programmable operating schedule including two or more time periods and one or more temperature set points for each of the two or more time periods, the programmable operating schedule stored in the memory;
an I/O block for sending and/or receiving signals to and/or from the one or more components of the HVAC system including one or more of a heating unit, an air conditioner unit, a humidifier unit, and a dehumidifier unit;
a controller coupled to the user interface, the memory, and the I/O block, the controller configured to generate one or more signals to control one or more components of the HVAC system in accordance with the programmable operating schedule, the controller further configured to allow a user to program at least a first time period of the two or more time periods of the programmable operating schedule to control at least one of the humidifier unit and the dehumidifier unit differently than during at least one other of the two or more time periods of the programmable operating schedule; and
wherein the controller is configured to allow a user to program the programmable operating schedule by allowing the user to:
