11h is embarking on a project to use a java based microcontroller (Tini) as a smart thermostat with a zone controlled HVAC system. Each floor vent will be controllable and each room will have it’s own temperature. 1-wire devices from Maxim-ic will be used to collect the temperature and motion sensors from each room and control the servo motors that are attached to the floor vents.<\/p>\n
I’d like to throw together some ideas about the zone hvac system before writing a large IPS (Internal Product Specification) or EPS (External Product Specification).<\/p>\n
I’ve been thinking about a system that could have a stored HVAC cycle for up to a week.<\/p>\n
Since each DS2770 has 40 bytes of memory, each temperature sensor could store its own temperature setting. This way a configuration file or a server would not have to exist to know what the temperature is set to for each sensor; the 1-wire network could be polled to determine what the current temperature setting is for a particular temperature sensor.<\/p>\n
