virtual relays

Used through physical relays in a Direct-to-Grid load control switch (LCS)to physically control and connect one or more assets, which can be, for example, HVACs, water heaters, and pool pumps. Each physical relay allows control signals to turn the asset behind the switch on or off.

An HVAC, for example, could include multiple components (such as a first stage compressor, second stage compressor, fan, and heat strip), each of which is connected to and controlled by a separate physical relay.

When sending a DRLC event, you might want to control only certain components. For example, the utility might want to turn off the compressors but keep the fan on. The switches accomplish this through the virtual relays, each of which is associated with multiple physical relays.
