Revision history [back]

The cooling and heating set point temperatures are controlled using the Control Type Schedule Name input field. This example shows a heating set point in winter and a cooling set point in summer. In the control type schedule, 1 = heating, 2 = cooling, 3 = the same cooling and heating set point temperature, and 4 = dual set point control (2 temperatures). When the single cooling and/or heating thermostats are used only a single set point temperature is active at any point during the simulation, for example in winter there is only a heating set point temperature and cooling will not occur. Same for cooling.

In this next example, there are 2 set point temperatures, one for heating and one for cooling. Remember that control type = 4 means dual set point temperatures. Heating and cooling can occur any time during the year depending on the zone loads and zone temperature with respect to the 2 temperature set points.
