The thermostat driftpoints are the temperatures that a room is allowed to drift up to or down to during periods of low or no occupancy. If the room temperature starts to go outside the driftpoint temperatures, the cooling or heating equipment will be activated, assuming the equipment is available to operate. TRACE will allow the room to drift up to or down to the driftpoint temperatures during the hours in which the people schedule for the room reads 5% or less; if the people schedule reads greater than 5%, the cooling thermostat will try to control the room to the design setpoints.

The thermostat schedules allow the user to enter heating and cooling setpoints based on time instead of occupancy. Thermostat schedules are created using the Library/Template Editors.

Note: If a cooling thermostat schedule is selected (other than the default “None”), then the program will ignore the entered cooling setpoints and driftpoints for the energy simulation. However, the setpoints will still be used during the design calculations. The heating thermostat schedules and driftpoints work identically.
