Abstract

See full text

Property-management or lock-setting thermostats have maximum and minimum set points locked in to prevent abuse of management-provided heating and/or air conditioning. An ePROM or similar internal memory device stores heating and cooling limit parameters that are set in by a technician at the time of installation. A plug-in flash memory module contains an unlock code to match the unlock code stored in said ePROM, to unlock the thermostat and allow the settings to be adjusted; when said flash memory module is removed the thermostat reverts to its lock condition. The thermostat can also respond to unusual rates of change of temperature to block furnace or A/C operation temporarily.
