The Home Energy Saver is capable of modeling both standard and programmable thermostats. The default thermostat assigned to a new session is a standard thermostat with the default schedule and temperature settings outlined in Table 6. Users can adjust the temperature and time schedules for the two periods (day and night), and can specify a separate schedule for weekdays and weekends/holidays.
Table 6. Default Thermostat Schedule for Standard Thermostats
Alternatively, users can choose a programmable thermostat, which defaults to the schedule outlined in Table 7. As with a standard thermostat, users can specify alternate times and temperatures for the four periods, to differentiate between weekday and weekend/holiday schedules.
Table 7. Default Thermostat Schedule for Programmable Thermostats
The thermostat schedule is sent as an input to the DOE-2 calculation engine where it is used in calculating energy consumption by the heating and cooling equipment.
