Overview

A programmable thermostat is required to keep costs down while keeping everyone as happy as possible with the temperature of the shop.

The programmable thermostat should:

Be remote controllable (all features)
- Wifi, indirect network connection such as serial to a laptop, xbee
Be able to control a heating device via 120V relay
- 1 GPIO
Be able to control a cooling device via 120V relay
- 1 GPIO
Be able to control a heating or cooling device by remote means
- Currently, X10 and X10 via network proxy are options
Have a user interface for people to interact with at the physical location
- LCD with buttons
Be able to monitor temperature accurately in one or more locations
- DS18B20+ temp sensors
- USB temperature sensor?
- Built-in temp sensor?
Have certain software capabilities
- Occupied hot target with hot-side hysteresis
- Unoccupied hot target with hot-side hysteresis
- Occupied cold target with cold-side hysteresis
- Unoccupied cold target with cold-side hysteresis
- Transition from occupied to unoccupied state after a timeout and audible alarm
- Local or remote user can silence alarm and reset timeout
