Abstract:
1. Wall thermostat configured to be mounted in a tenant comfort zone within a managed property, and configured to communicate with a climate control unit for said tenant comfort zone to adjust the temperature of air within said tenant comfort zone; the wall thermostat comprising a housing, a controller circuit within said housing and containing a temperature control program in which one or more temperature set-points are established; an air temperature sensor coupled to the controller circuit; the controller circuit being operatively coupled to a signaling unit to provide a call for heating or cooling to said climate control unit when the air temperature in said tenant comfort zone is beyond an associated one of said temperature set-points; one or more operator controls located on the thermostat housing and coupled to said controller circuit to permit at least limited adjustment of the one or more set-points in the temperature control program within one or more set-point limits; said controller circuit being configured to be set into a lock condition in which at least certain parameters including said one or more set-point limits within the temperature control program are disabled from adjustment, and an unlock condition in which said parameters are enabled for adjustment; an ePROM within said housing and operatively coupled to said controller circuit and containing an unlock code specific to said tenant comfort space; and a receptacle in said housing, operatively coupled to said ePROM, and adapted to receive a plug-in flash memory module that contains an unlock code that matches the unlock code stored in said ePROM; such that when said flash memory module is in place in said receptacle, the controller is set into its unlock condition to allow the operator controls on the thermostat housing to adjust said parameters of the thermostat temperature control program, and when said flash memory module is removed therefrom, the controller circuit returns to its lock condition wherein the operator controls are disabled from adjusting said parameters.
