I am looking for a system that would allow a Unix machine to control the air conditioning and heating systems in a building. What would be ideal is a system with software, temperature sensors and relays which would allow the Unix machine to function as a smart thermostat. Indoor temperatures could be programmed to go up in the early morning and drop down after business hours, on weekends and on holidays to save energy. Ideally the system would run off a serial port and not take up a bus slot. Please email me if you know of anyone making such a system. -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Fred Fierling Tel: 604 875-1461 Microplex Systems Ltd, 265 East 1st Avenue uunet!mplex!fff Fax: 604 875-9029 Vancouver, BC, V5T 1A7, Canada

If you want alarms/phone call and power shutdown, there are these SAM units advertised in the back of Digital Review and Hardcopy mags. They are more expensive: $1000? The SAM might have an aux relay output to implement a thermostat system. If you really want thermostat control, I'm not sure. But the X10 BSR home control system (DAK had some) might do it. It has relays and power switches.
