    5 sec to save and exit. Programmable Thermostats Programmable thermostats contain all of the functionality of the non-programmable thermostats, but they also keep track of the date, day of week, and time of day for scheduling purposes. Programming This section describes how to program the thermostat after it has been installed and configured.
  • Page 36: Scheduling

    Operation Scheduling The thermostat can be configured for two periods (day and night) or four periods (morning, day, evening, and night).The chosen number of periods are applied to each day of the week when you program the thermostat. Each period can have a unique start time, heat setpoint, cool setpoint, and fan setting.
