| 摘要 |
An electronic controller device for automatic control of a heating, ventilating, air conditioning or refrigeration (HVAC&R) system, which has at least a delayed start controller that is capable of delaying sending of a signal to power on a load unit and achieve a selected conditioned space temperature variation, and a demand regulator controller that is capable of calculating on times and off times to obtain a selected electrical demand. The electronic controller device can include a computer-readable storage medium that comprises programs to implement the delayed start and demand regulator controllers, and optionally other controller modules, can delay OEM ON signals and/or adjust the “on” and “off” states, and/or provide other load unit control, to manage and reduce energy consumption and/or demand. |
