Demand settings
When a demand response is received from the utility company, the heating and
cooling set points will be adjusted according to the absolute temperature or offset
shown here. If the set point at the time of the event is more favorable (uses less
energy) than what you have programmed, the Infinity Touch Control Thermostat
will use the more favorable set point for the duration of the event.

Response Limits
Response limits are minimum heating and maximum cooling temperatures allowed
during a utility event. These limits are not exceeded and are intended to protect the
occupant premises from extreme temperatures that might otherwise be imposed by
a utility event.
