Appendix A: VVT Zone II Points/Properties

Setpoints

Navigation: i-Vu® / Field Assistant:
Select a color band on the setpoint graph to see the current setpoints in the Heating and Cooling fields. The values in this
graphic are Fahrenheit. See setpoint descriptions below.
NOTE This graphic is an example only. Your setpoints may differ.
Occupied Setpoints
The occupied setpoints described below are the setpoints under normal operating conditions. The Demand Level 1–3
setpoints apply if demand limiting is used.
Demand limiting is a cost-saving strategy to reduce energy consumption. The strategy expands the occupied heating and
cooling setpoints when the system reaches one of 3 levels of consumption. With the expanded setpoints, the equipment
works less, thereby saving energy. By default, Demand Level 1 expands the occupied heating and cooling setpoints by
1 °F ( .5°C), Demand Level 2 by 2 °F (1.1 °C), and Demand Level 3 by 4 °F (2.2 °C). If the occupied heating or
cooling setpoints change, the (effective) demand level setpoints automatically change by the same amount. See
Sequence of Operation (page 46) for more information.
Point Name/Description
Occupied Heating – Green
