Patent ID: 7130719

Claim:
A system for managing environmental comfort at a site, the site having a temperature and environment management system, the temperature and environment management system being supplied with energy from an energy provider, comprising: a humidity sensor for sensing humidity at the site; a temperature sensor for sensing air temperature at the site; a thermostatic device in communication with the energy provider to receive a current cost of energy, the thermostatic device being coupled to the humidity sensor and the temperature sensor and configured for receiving an input from a user, the input including a temperature setpoint and of one of a plurality of comfort level scenarios, wherein each of the comfort level scenarios relate to a willingness to pay for energy at the expense of comfort, wherein the thermostatic device is operable to determine an effective setpoint as a function of the temperature setpoint and the sensed humidity and determine a deadband defined by the effective setpoint and an offset from the effective setpoint, wherein the offset is based on the selected comfort level scenario and the current level of energy cost.
