Indicators and Adjustments, cont. Your thermostat is preset to cycle your system off and on at 1oF above and below the Set Temperature. For maximum system efficiency and a sustained comfortable temperature your system should cycle 3 - 5 times per hour. If your system is cycling either too often or not often enough, then use a small Phillips-head screwdriver to turn the Span Adjust left or right to change the cycle time. 1. Remove the thermostat from the wall plate. 2. To make your system run LONGER, turn the Span Adjust clockwise. 3. To make your system run SHORTER, turn the Span Adjust counter clockwise. 4. Reattach the thermostat to the wall plate. Note: The Span range is 0.6oF - 3oF. The Span setting remains the same in both the Heat and Cool modes and can be changed regardless of what position the System Switch is in. 24
