1)Select Reversing Valve Output (SS/HP switch must be set at HP, omitted if SS/HP switch is SS Position) – The O/B option is factory set at "O" position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermo- stat you are replacing or the heat pump being installed with this thermostat requires a "B" terminal, to energize the changeover relay in HEAT, the O/B option should be set at "B" position.

2)Program Options 1F80 only –This control can be conﬁgured for 5/2 day or 5/1/1 day programming or non-programming mode. The default setting is P2, indicating 5/2 day program- ming. The programs per week can be toggled to P3 or P0

by pressing the or keys. A selection of 0 Days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.

3)Select Cool Savings™ and value – Selects the Cool Savings feature On or OFF. If selected On, press MENU to select the amount of adjustment for the feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. Default value is 3 (3°). In normal operation "Saving" will appear under "Fan".

Cool Savings is an optional energy saving feature that can reduce your cooling costs. It is based on the principal that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when the cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower the indoor humidity. Cool Savings very slowly adjusts the setpoint temperature to make the setpoint closer to the displayed temperature, to a maximum number of degrees selected. Adjusting the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will actually be higher than the thermostat displays, but the reduction in humidity will allow comfort at the slightly higher temperature. When Cool Savings is making adjustments, "Save" will show next to the setpoint temperature and the room temperature may vary within the adjustment range selected.

If this feature is selected OFF, no change will occur when the cooling system is continually running during periods of high demand.
