A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies a certain number of degrees from the set-point. This variation is the “swing”.
Your system should cycle on about 3 to 6 times per hour.
- A smaller swing setting increases the number of cycles, so room temperature is more constant relative to your set temperature. For example setting # 1 provides maximum comfort.
- A larger swing number (#9 for example) decreases the number of cycles per hour. You may feel a slight increase in the amount of temperature variation but this setting saves more energy.
We recommend setting # 4 which provides a balance of comfort and energy savings. This is also the default value that the thermostat already has in it when it is shipped.
To change the swing setting:
- Place the System Mode switch in the “Off” position.
- Hold down the Save button for approximately 4 seconds (until the display changes to a single number).
- You will see a number between 1 and 9 in the display.
- Use the up and down buttons to adjust this to the desired level.
Actual temperature variation will vary depending on the conditions. As an approximation:
1 +\- 0.25 F
2 +\- 0.50 F
3 +\- 0.75 F
4 +\- 1.00 F
5 +\- 1.25 F
6 +\- 1.50 F
7 +\- 1.75 F
8 +\- 2.00 F
9 +\- 2.25 F
Example: For tightest control, set swing setting on # 1 which is plus or minus 0.25F degrees. If you use a setpoint at 70F, the highest it will get to is 70.25 F, the lowest it will get to is 69.75F
