Demand Limiting

The Unit Vent accepts 3 levels of demand limit from the network. In response to a demand limit, the unit
decreases its heating setpoint and increases its cooling setpoint to widen the range in order to immediately lower
the electrical demand. You can change the responding temperature adjustment for both heating and cooling and
each demand level. The response to a particular demand level may also be set to 0.
