According to certain embodiments, a thermostat is configured for use in a climate control system. The thermostat is operable to use two-way communication for communicating operational information between the thermostat and at least one rooftop unit (RTU) within the climate control system. For example, the two-way communication comprises sending first operational information to the RTU and receiving second operational information from the RTU. The operational information comprising one or more climate control commands, setpoints, configuration information, diagnostics, and/or sensor data. The thermostat is further operable to operate the climate control system based on the operational information communicated between the thermostat and the RTU.

Communications between thermostat and rooftop unit of climate control system

According to certain embodiments, a device is configured for use in a climate control system. The device is operable to determine, based on configuration information, whether thermostat functionality of the device is enabled or disabled and whether sensor functionality of the device is enabled or disabled. The device is further operable to operate according to the configuration information. Thus, according to certain embodiments, the device can be configured as a thermostat, a sensor, or both.

Sensor features for climate control system

According to certain embodiments, a controller is operable to instruct a climate control system to operate according to an occupied mode or an unoccupied mode based on a pre-defined schedule. The occupied mode uses pre-defined settings associated with an occupied status, and the unoccupied mode uses pre-defined settings associated with an unoccupied status. The controller is operable to receive an indication that an occupancy sensor detects a space as being occupied. In response to receiving the indication when the pre-defined schedule requires the climate control system to operate in the unoccupied mode, the controller is operable to instruct the climate control system to use the pre-defined settings associated with the occupied status during an override time period.

Operating a climate control system based on occupancy status

A method of controlling operations of an HVAC system includes measuring temperature within an enclosed space, receiving a setpoint temperature within the enclosed space, calculating a temperature difference between the measured temperature and the received setpoint temperature, and determining whether the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to a first predetermined temperature differential value. If the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to the first predetermined temperature differential value, determining whether the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to a second predetermined temperature differential value. If the temperature difference between the measured temperature and the received setpoint temperature is less than the second predetermined temperature differential value, selecting a first operating mode of a plurality of operating modes of the HVAC system.

Systems and methods for variable control and operation of HVAC components

An equipment management system including a controller and a server. The controller communicatively couples to one or more remote systems. At least one of the remote systems includes a heating, ventilation, and air conditioning (HVAC) system, a refrigeration system, or a building automation system. The controller receives telemetry data associated with the operation of the one or more remote systems and with individual components of the one or more remote systems. The controller communicates at least a portion of the received telemetry data to the server. The server determines one or more operational commands for the one or more remote systems. The one or more operational commands are determined based on the telemetry data communicated from the controller to the server. The server communicates the one or more operational commands to the controller. The controller communicates the one or more operational commands to the one or more remote systems.

HVAC, refrigeration, and automation equipment management

A controller configured to communicatively couple to at least two sets of equipment. At least one set of equipment includes heating, ventilation, and air conditioning (HVAC) equipment, refrigeration equipment, or building automation equipment. For each set of equipment, the controller determines an operation schedule for the respective set of equipment. The controller also communicates the operation schedule to the respective set of equipment, for each set of equipment. The controller may receive a request to perform mass scheduling. The request indicates which sets of equipment and which settings of the operation schedule are to be configured using the mass scheduling. The controller may also communicate the same values for the settings that the request indicates to configure using the mass scheduling to each set of equipment that the request indicates to configure using the mass scheduling.
