• Optimum Start: This is an energy-efficient feature that adjusts the start time of your heating system. For
example, on cold days your heating system will start earlier to ensure that your home is warm when you
wake in the morning. On warmer days, heating will begin later to save energy costs. (See page 29 to turn
on this feature.)
• Summer/winter time change: The thermostat automatically changes the clock time to correspond with
changes to and from daylight savings time. (See page 28 to turn off this feature.)
• Temperature offset: In some cases, the thermostat must be installed in a location that does not
accurately control temperature for optimum comfort in other rooms. You can set the thermostat to
compensate for this by adjusting the offset (see page 29).
• Proportional band width: If your heating system is oversized for your home, you can compensate by
increasing the width of the control proportional band up to 3°C (see page 29).
• Cycle rate and minimum boiler on/off time: Adjusting these features can help your climate control
system work more efficiently for increased comfort and economy. See page 31 to find recommended
settings for your system.
