An environmental control device (), such as a thermostat, is disclosed. The environmental control device () has one or more terminals (-) for connecting to an HVAC system () and performs over current management of the terminal (-) when connected to the HVAC system ().

Thermostat having over current management

An environmental control device (), such as a thermostat, is disclosed. The environmental control device () has one or more terminals (-) and a respective configurable interface circuit (-) coupled to each terminal for selectively configuring the terminal (-) for a corresponding input or output connection to an HVAC system ().

Thermostat having configurable interface connections

A system and method is provided that facilitates controlling and monitoring environmental conditions in buildings. The system may include at least one rack including: a plurality of slidable field panels mounted in a housing. The slidable field panels may be in side-by-side relation in a horizontal direction and may be configured to independently slide at least partially out of a front side opening of the housing via a plurality of slides. The slidable field panels may include a plurality of components mounted to vertical walls thereof, including: transformers and building control modules. The rack may also include a terminal panel including a plurality of connection terminals facing a back side opening of the housing. The connection terminals may be respectively wired to respective terminals of the transformers and building control. The system may include at least one data processing system including at least one processor configured to communicate with the building control modules to cause the rack when a heating, ventilating, and air conditioning (HVAC) system is wired to at least some of the connection terminals, to monitor and control the HVAC.

System and method for controlling and monitoring environmental conditions in a building using an integrated rack

A system and method is provided that facilitates testing a building control system. The system may include at least one rack including: a housing; a terminal panel; and a plurality of slidable field panels mounted in the housing in side-by-side relation. The terminal panel may includes a plurality of connection terminals that are wired to respective component terminals of a plurality of components mounted to the field panels. Each field panel may be configured to independently slide at least partially out of a front side opening of the housing via a plurality of slides mounted to each field panel and to the housing. The system may also include at least one story board including: a schematic illustration mounted to a frame that depicts components of a heating, ventilating, and air conditioning (HVAC) system; and a plurality of instruments mounted to the frame at locations on the illustration adjacent the depicted components of the HVAC system, which instruments receive inputs from and provide outputs to the building control system through wires connected to the connection terminals of the at least one rack, so as to mimic aspects of an HVAC system in order to test the configuration of the building control system in the at least one rack.
