The deadbolt on the door was also replaced with an electronically controlled unit from Kwikset. Each button on the three-button switch by the front door was programmed to set up the electronics for a particular activity. Pressing HOME, for example, commands the Control4 system to turn on certain lights and set the thermostat to either 65 or 69, depending on the outside temperature and the time of year. PARTY brightens the lights by the bar to full intensity, while others stay at a softer 50 percent intensity level; tunes the cable box to a favorite music station and distributes the audio to speakers in the living room, and kitchen; and turns on the 50-inch TV in the family room.
