Abstract

The present invention is related to a wide variety of thermostats and thermostats/humidistats for air temperature and relative humidity control in buildings having heating, cooling and humidification systems. We suggest using a forced air device to take a representative air sample near the building occupant'"'"'s location in order to enhance indoor climate control and improve its accuracy. When this forced air device is used, the existing standard thermostat or standard thermostat/humidistat becomes a non-inertial thermostat or thermostat/humidistat. We also suggest to equip non-inertial programmable thermostat or thermostat/humidistat as well as standard programmable thermostat or thermostat/humidistat with an advisory computing system. This system will provide the occupant with a guiding tool and enable him to make an informative decision about set points selection in relation to the projected energy savings or energy over-consumption at particular mode of operation, as compared to the base set points. The invention is applicable for stationary as well as mobile thermostat or thermostat/humidistat.
